TY - JOUR. T1 - Induction of phosphatidylinositol 3-kinase and serine-threonine kinase-like immunoreactivity in rabbit spinal cord after transient ischemia. AU - Sakurai, Masahiro. AU - Hayashi, Takeshi. AU - Abe, Koji. AU - Itoyuama, Yasuto. AU - Tabayashi, Koichi. PY - 2001/4/13. Y1 - 2001/4/13. N2 - The mechanism of spinal cord injury has been thought to be related with tissue ischemia, and spinal motor neuron cells are suggested to be vulnerable to ischemia. To evaluate the mechanism of such vulnerability of motor neurons, we attempted to make a reproducible model of rabbit spinal cord ischemia. Using this model, the inductions of phosphatidylinositol 3-kinase (PI3-k) and serine-threonine kinase (Akt) were investigated with immunohistochemical analyses for up to 7 days of the reperfusion following 15 min of ischemia in rabbit spinal cord. It has been demonstrated that both PI3-k and its downstream effector, Akt mediate growth factor-induced neuronal survival. Spinal cord sections from ...

The phospholipid and phospholipid fatty acid compositions of mixed murine spinal cord neuronal cultures are reported. The phospholipid composition was primarily comprised of ethanolamine glycerophospholipids (44.8%) and choline glycerophospholipids (43.5%). Plasmalogens made up 29.1% of the ethanola...
The spinal cord is surrounded by cerebrospinal fluid (spinal fluid) throughout its course in the spinal canal. The spinal fluid serves as a buffer of fluid that surrounds the spinal cord providing protection and insulation from movements and trauma to the body. The spinal fluid is kept in place by two thin membranes- the arachnoid and dura. The arachnoid is a very thin see through membrane that is suspended in the spinal fluid while the dura is a slightly thicker and stronger membrane that surrounds the spinal fluid space.. A ventral spinal cord herniation may occur if a breach or weakness of the dura occurs. Spinal fluid can leak through this opening causing headaches as part of a condition called spontaneous intracranial hypotension. In rare circumstances, the spinal cord may be pushed forward and protrude through the breach in the dura to produce a ventral spinal cord herniation. This condition usually occurs in the thoracic spine and can cause numbness and weakness in the legs with walking ...

N2 - Generation of the appropriate types, numbers and distribution of neurons during the development of the nervous system requires the careful coordination of proliferation, differentiation, and patterning. In this work, we analyzed the roles of a repulsive axon guidance protein, draxin, on the development of chick spinal cord dI3 interneuron. draxin mRNA and/or protein were detected in the roof plate at first and then the boundary region between the ventricular and the mantle zones in chick spinal cord and dorsal basement membrane of the chick spinal cord. Overexpression of draxin caused the decreased and delayed migration of the dI3 interneuron, the reduction of progenitor cell proliferation, and abnormal ...
Author(s): Papinutto, Nico; Schlaeger, Regina; Panara, Valentina; Zhu, Alyssa H; Caverzasi, Eduardo; Stern, William A; Hauser, Stephen L; Henry, Roland G | Abstract: The source of inter-subject variability and the influence of age and gender on morphometric characteristics of the spinal cord, such as the total cross-sectional area (TCA), the gray matter (GM) and white matter (WM) areas, currently remain under investigation. Understanding the effect of covariates such as age, gender, brain volumes, and skull- and vertebra-derived metrics on cervical and thoracic spinal cord TCA and GM areas in healthy subjects would be fundamental for exploring compartment specific changes in neurological diseases affecting the spinal cord. Using Magnetic Resonance Imaging at 3T we investigated 32 healthy subjects using a 2D phase sensitive inversion recovery sequence and we measured TCA, GM and WM areas at 4 cervical and thoracic levels of the spinal cord. We assessed age and gender relationships of cord measures and
Neural stem/progenitor cell (NSPC) transplantation is a promising therapy for spinal cord injury (SCI). However, little is known about NSPC from the adult human spinal cord as a donor source. We demonstrate for the first time that multipotent and self-renewing NSPC can be cultured, passaged and transplanted from the adult human spinal cord of organ transplant donors. Adult human spinal cord NSPC require an adherent substrate for selection and expansion in EGF (epidermal growth factor) and FGF2 (fibroblast growth factor) enriched medium. NSPC as an adherent monolayer can be passaged for at least 9 months and form neurospheres when plated in suspension culture. In EGF/FGF2 culture, NSPC proliferate and primarily express nestin and Sox2, and low levels of markers for differentiating cells. Leukemia inhibitory factor (LIF) promotes NSPC proliferation and significantly enhances GFAP expression in hypoxia. In differentiating conditions in the presence of serum, these NSPC show multipotentiality, expressing

The ability of regenerating fiber tracts to maintain or regain their normal pathways following a spinal cord transection was investigated. Utilizing the Holmes silver technique, examination of ran- domly chosen transected spinal cords of goldfish verified that the transections were complete. Normal goldfish spinal cords were studied using two micra plastic cross sections and horseradish peroxidase (HRP) labeled longitudinal sections. Descending and ascending tracts were identified by transecting the spinal cord and examining sections for degeneration. Following regeneration, two micra plastic cross sections stained with toluidine blue, and longitudinal and cross sections of HRP labeled regenerate goldfish spinal cords (labeling of either the entire spinal cord or a limited number of fibers) were examined. Regeneration of the fibers was found to be limited to 5 or 6 millimeters. With HRP labeling of the regenerated spinal cord either rostral or caudal to the original transection, labeled fibers ...
In contrast to cyclin D1 and D2, the expression level of cyclin D3 was high in the hindbrain at the E15.5 stage (Figure 3I, arrowhead). Moreover, in the midbrain cyclin D3 was expressed in cells closer to the ventricle than those expressing cyclin D2 (Figure 3H, I, arrows).. Discussion. At the E10.5 stage, all three D-type cyclins were expressed in most of the spinal cord cells but cyclin D1 and D3 showed higher expression levels in the dorsal half of the spinal cord. Wianny et al. (1998) found that the dorso-ventral gradient of the cyclin D1 transcript also occurs in the spinal cord of 7-9 somite-stage embryos. However, in our study we found that at the E10.5 stage cyclin D2 was not missing from the floor plate and also that cyclin D3 was not expressed only ventrally, as was reported for the transcripts of the genes in 7-9 somite stage embryos by Wianny et al. (1998). This may have been due to altered expression patterns of these genes during the time course of spinal cord development and ...
Bcl11a is expressed in both presynaptic sensory neurons and postsynaptic spinal target neurons (Fig. 1). We next asked whether Bcl11a is required for correct wiring, and if so, on which site. Central axons of sensory neurons were labeled at E16.5 with DiI. In the superficial dorsal horns of Brn4-Cre;Bcl11a mutants, the density of DiI-positive fibers was greatly reduced and the remaining fibers appeared disorganized. Only a few axons crossing the midline or located in a dorsolateral region of the dorsal horn were detectable by DiI labeling in mutants (Fig. 5A,B). TrkA (Ntrk1 - Mouse Genome Informatics) -positive nociceptive fibers preferentially terminate in the superficial dorsal horn. Immunohistological analysis with antibodies against TrkA or aquaporin 1, a water channel protein that is expressed by small-diameter nociceptive fibers (Oshio et al., 2006), invariably revealed almost complete loss of such fibers in the dorsal horn of Brn4-Cre;Bcl11a mutants (Fig. 5C-F). Similar results were ...

Spinal nerves carry nerve impulses to and from the spinal cord through two nerve roots: Motor (anterior) root: Located toward the front, this root carries impulses from the spinal cord to muscles to stimulate muscle movement. Sensory (posterior) root: Located toward the back, this root carries sensory information about touch, position, pain, and temperature from the body to the spinal cord. In the center of the spinal cord, a butterfly-shaped area of gray matter helps relay impulses to and from spinal nerves. Its wings are called horns. Motor (anterior) horns: These horns contain nerve cells that carry signals from the brain or spinal cord through the motor root to muscles. Posterior (sensory) horns: These horns contain nerve cells that receive signals about pain, temperature, and other sensory information through the sensory root from nerve cells outside the spinal cord. Impulses travel up (to the brain) or down (from the brain) the spinal cord through distinct pathways (tracts). Each tract ...
When spinal stenosis is present in the cervical spine (cervical stenosis), the spinal cord may be compressed. This may not only lead to pain, but it may lead to paralysis, due to compression of the spinal cord. Pressure on the spinal cord may also create a condition known as myelopathy, in which there is a partial injury to the spinal cord, leading to progressive loss of control of the lower extremities, and possibly a loss of control of bowel and bladder function. The patient may also experience shocks traveling from the neck down the spine, which is known as a LHermitte sign. When myelopathy is present, due to cervical spinal stenosis and spinal cord compression in the cervical spine, the MRI scan of the cervical spinal cord will frequently show a high intensity signal, or a bright spot, in the cervical spinal cord. This represents a spinal injury, and may be incomplete, in which case the patient will have function of the lower extremities, or may be a complete spinal cord injury, in where ...

DESCRIPTION (provided by applicant): Nervous system development encompasses generation of neural cells, followed by their positioning and differentiation to culminate with establishment of specific connections that enable the execution of innumerable functions. Although both the developing and mature nervous system exhibit tremendous plasticity, comparatively, the former has a greater capacity for remodeling. When the neural tissue is injured or its function is imbalanced, as for patients suffering from spinal cord injury or epilepsy, recreating the remarkable plasticity of the developing nervous system towards repairing and regenerating damaged cells and connections is the ultimate goal. Understanding developmental processes becomes crucial to devising therapies targeting nervous system regeneration and repair. Two major developmental cues are key for nervous system development, the morphogentic protein, Sonic hedgehog (Shh), and early electrical activity. Although many aspects of their action ...
The nitric oxide synthase 1 adaptor protein (NOS1AP) is an adaptor protein implicated in a number of human conditions including schizophrenia, anxiety and cardiac QT syndrome. Previous studies have shown that NOS1AP and some of its isoforms associate with the tumor suppressor protein scribble. Since scribble has been linked to the Hippo pathway, I set out to determine if NOS1AP associates with the Hippo pathway and whether it controls aspects of neuronal development. Here I show that NOS1AP and NOS1APc interact with the transcriptional co-activator yes-associated protein (YAP), a component of the Hippo cascade. Further both NOS1APa and NOS1APc show partial co-distribute with YAP in HEK293Tcells, with NOS1APc having better co-distribution. In situ hybridization and immunocytochemistry studies reveal that NOS1APc is expressed in the developing spinal cord. NOS1APc is expressed in the floor plate and roof plate and shows a similar profile to radial glial cells. In ovo electroporation of cDNA ...
Spinal cord disorders like spina bifida arise during early development when future spinal cord cells growing in a flat layer fail to roll up into a tube. In the Dec. 6 issue of Nature Cell Biology, researchers from the Johns Hopkins University School of Medicine team with colleagues at the University of California, Berkeley to report a never-before known link between protein transport and mouse spinal cord development, a discovery that opens new doors for research on all spinal defects.
Face & Neck Pain: Your C2 cervical space (upper neck) sends and receives nerve signals from the spinal cord to the face and neck. Chronic pain in the lower face region (below the upper jaw) may indicate damage or injury to the top of the spinal cord in this area. To relieve pain stemming from the cervical spinal area, the electrode leads would be placed in the C2 and/or C3 epidural space (empty space between the bones).. Neck, Shoulder, & Hand Pain: The C2 to C4 areas of the spinal cord are responsible for pain felt in the neck as well as pain that radiates into the shoulder and down into the hand. When an injury or damage occurs in this upper-to-mid cervical area, chronic pain can occur.. Forearm & Hand Pain: When the spinal cord suffers damage in the C4 to C7 portion of the spinal cord, pain can radiate into the forearm and/or hand. An SCS device can stop these pain signals at the source and provide relief.. Front of the Shoulder Pain: Chronic pain in the front of the shoulder may be an ...
Afferent input has been shown to play a major role in our capacity to reactivate spinal circuits that generate coordinated rhythmic flexion and extension of the limb muscles in spinal cord injury patients. Our studies revealed that stimulation of sacrocaudal afferents (SCA) is a potent means for activating the locomotor central pattern generators (CPGs) in rodents spinal cords that lack the descending control from the brain. These studies showed that capacity of SCA to induce the locomotor rhythm depends on activation of sacrocaudal neurons the crossed and uncrossed projections of which, ascend through the ventral and lateral white matter funiculi (VF,VLF, LF, and DLF) to the limb innervating segments of the cord. The project examines the axonal projections, spatial distribution, organization and physiological properties of these sacrocaudal neurons and evaluates their role in the generation of afferent induced rhythmicity in the spinal cord. The studies are performed in collaboration with Dr. ...

STUDY DESIGN: Experimental study of corticospinal axonal sprouting in an organotypic slice culture model. OBJECTIVE: To develop an in vitro model that simplifies the study of various factors regulating neuronal regeneration. SUMMARY OF BACKGROUND DATA: Spinal cord injury leads to permanent neurologic damage, mainly due to the inability of the adult central nervous system to regenerate. Much attention has been focused on promoting axonal regeneration and sprouting, either by exogenous administration of various neurotrophic factors or by the antagonization of factors inhibiting regeneration. METHODS: An in vitro system that allows coculture of slices from rat sensorimotor cortex and spinal cord (p4) was established. Two groups of cultures were investigated: In the first group, intact spinal cord slices were cultured adjacent to sensorimotor cortex slices, while in the second group the spinal cord slices were sagittally cut into halves, with the sectioned interface placed directly adjacent to the ...

AU - Hackney, D. B.. AU - Glasser, S. A.. AU - Wehrli, F. W.. AU - Grossman, R. I.. PY - 1990/1/1. Y1 - 1990/1/1. N2 - Routine evaluation of axial MR images of the cervical spine with high-intensity CSF (long TR/TE spin-echo or gradient-echo images) revealed apparent narrowing of the cords anteroposterior diameter when these images were compared with corresponding postmyelography CT scans. This discrepancy was believed to be due to the truncation artifact at the CSF-cord boundary. To examine the truncation effect, we compared cord diameters in 12 patients on postmyelography CT scans and MR images and then compared these with MR scans of normal volunteers and of an agar-saline spine phantom. There was an artifactual diminution of the cord diameter in the 128-step phase-encoding axis of the 128 x ...

N2 - In the spinal dorsal horn (DH), transmission and modulation of peripheral nociceptive (pain-inducing) messages involve classical neurotransmitters and neuropeptides. We show that approximately half of DH neurons use ATP as a fast excitatory neurotransmitter acting at ionotropic P2X postsynaptic receptors. ATP was not codetected with glutamate but was coreleased with the inhibitory neurotransmitter GABA. Moreover, adenosine, probably generated by extracellular metabolism of ATP, finely tuned GABAergic inhibitory postsynaptic currents. Differential modulation of excitatory versus inhibitory components of this mixed cotransmission may help to explain changes in sensory message processing in the DH during mechanical hyperalgesia and neuropathic pain..

A first-ever spinal cord imaging meeting was sponsored by the International Spinal Research Trust and the Wings for Life Foundation with the aim of identifying the current state-of-the-art of spinal cord imaging, the current greatest challenges, and greatest needs for future development. This meeting was attended by a small group of invited experts spanning all aspects of spinal cord imaging from basic research to clinical practice. The greatest current challenges for spinal cord imaging were identified as arising from the imaging environment itself; difficult imaging environment created by the bone surrounding the spinal canal, physiological motion of the cord and adjacent tissues, and small cross-sectional dimensions of the spinal cord, exacerbated by metallic implants often present in injured patients. Challenges were also identified as a result of a lack of critical mass of researchers taking on the development of spinal cord imaging, affecting both the rate of progress in the field, and the
We reviewed the MR images of 32 patients with cervical myelopathy, showing lesions of high signal intensity in the spinal cord on the sagittal T2 weighted images (T2WI) after surgery: 16 with OPLL; 9 with spondylosis; 4 with disc herniation and 3 with trauma. All images were obtained on a superconducting 1.5 Tesla system. The lesions were classified into five groups, according to the shape and grade of signal intensity on the sagittal T2WI: (I) oval-shaped lesion of signal intensity less brighter than CSF with blurred margin, (II) longitudinal linear-shaped lesion of signal intensity similar to CSF, (III) spindle-shaped lesion of signal intensity similar to CSF, (IV) round-shaped lesion of signal intensity similar to CSF and (V) mixed-types lesions which consisted of group I and II. The present study was summarized as follows: 1) Oval-shaped lesions were seen in the cases of disc herniation and spondylosis with relatively short duration of the symptom, presumptively with relatively short duration of the

During spinal cord development the proliferation, migration and survival of neural progenitors and precursors is tightly controlled, generating the fine spatial organisation of the cord. In order to understand better the control of these processes, we have examined the function of an orphan receptor protein tyrosine phosphatase (RPTP) PTPγ, in the developing chick spinal cord. Widespread expression of PTPγ occurs post-embryonic day 3 in the early cord and is consistent with a potential role in either neurogenesis or neuronal maturation. Using gain-of-function and loss-of-function approaches in ovo, we show that PTPγ perturbation significantly reduces progenitor proliferation rates and neuronal precursor numbers, resulting in hypoplasia of the neuroepithelium. PTPγ gain-of-function causes widespread suppression of Wnt/β-catenin-driven TCF signalling. One potential target of PTPγ may therefore be β-catenin itself, since PTPγ can dephosphorylate it in vitro, but alternative targets are also ...

Single-shock stimulation of a dorsal root at intensities sufficient to activate high-threshold C-primary afferent fibres elicited VRPs lasting for 15-20 sec in the corresponding ventral root. The VRP consisted of 3 distinct parts: the early, slow and prolonged components, as previously described (Thompson et al. 1992), where the early represents Aβfibre-evoked mono- and polysynaptic responses lasting for tens of milliseconds, the slow is a largely ...
This dissertation describes research to elucidate the early steps in the process of synapse formation in the zebrafish spinal cord. One question is how presynaptic proteins are trafficked and recruited to nascent synapses. Previous work has suggested two possible models of presynaptic transport, either (1) most presynaptic proteins are transported together or (2) two types of transport packets, synaptic vesicle (SV) protein transport vesicles (STVs) and Piccolo-containing active zone precursor transport vesicles (PTVs), transport the necessary components separately. We tested these models using in vivo imaging in zebrafish spinal cord and found that the recruitment of at least three distinct transport packets during presynaptic assembly of a glutamatergic synapse occurs in an ordered sequence. First, STVs are stabilized at future synaptic sites, then PTVs, followed by a third transport packet type carrying Synapsin, a cytosolic protein that can tether SVs to actin. These results identify an ...
Researchers at University of California, San Diego School of Medicine report a previously unappreciated phenomenon in which the location of injury to a neurons communication wire in the spinal cord - the axon - determines whether the neuron simply stabilizes or attempts to regenerate. The study, published April 30 by Neuron, demonstrates how advances in live-imaging techniques are revealing new insights into the bodys ability to respond to spinal cord injuries.. While the body of a neuron is small, its axon can extend far up or down the spinal cord, which is about one and half feet long in humans. Along that distance, the axon branches out to make hundreds of connections with other cells, sending out signals that allow us to sense and respond to the world around us. Unless something happens to disrupt the axons reach, that is. Adult human axons in the brain and spinal cord are very limited in their ability to regenerate after injury - a hurdle that many researchers are trying to overcome in ...
Ischemic tolerance is an endogenous neuroprotective phenomenon induced by sublethal ischemia. Ischemic preconditioning (IPC), the first discovered form of ischemic tolerance, is widely seen in many species and in various organs including the brain and the spinal cord. Ischemic tolerance of the spinal cord is less familiar among neurosurgeons, although it has been reported from the viewpoint of preventing ischemic spinal cord injury during aortic surgery. It is important for neurosurgeons to have opportunities to see patients with spinal cord ischemia, and to understand ischemic tolerance of the spinal cord as well as the brain. IPC has a strong neuroprotective effect in animal models of ischemia; however, clinical application of IPC for ischemic brain and spinal diseases is difficult because they cannot be predicted. In addition, one drawback of preconditioning stimuli is that they are also capable of producing injury with only minor changes to their intensity or duration. Numerous methods to ...
A joint study by Professor Jonas Friséns research group at Karolinska Institute and their colleagues from France and Japan, and published in Cell Stem Cell, shows how stem cells and several other cell types contribute to the formation of new spinal cord cells in mice and how this changes dramatically after trauma. The research group has identified a type of stem cell, called an ependymal cell, in the spinal cord. They show that these cells are inactive in the healthy spinal cord, and that the cell formation that takes place does so mainly through the division of more mature cells. When the spinal cord is injured, however, these stem cells are activated to become the dominant source of new cells ...
Embryonic stem (ES) cells are a unique system to model mammalian embryonic development in an accessible in vitro setting. The ability of ES cells to generate any cell type found in our organism can be harnessed to study how cellular diversity is established during development. We demonstrate this by recapitulating key aspects of neural tube patterning and spinal cord development in differentiating ES cells, leading to efficient production of spinal motor neurons in vitro. Access to a virtually unlimited supply of spinal motor neurons creates a unique opportunity to decipher molecular processes governing the conversion of a pluripotent stem cell to a committed and differentiated cell type at global and comprehensive level. Currently we examine how differentiating cells integrate patterning signals and translate them into lasting changes in chromatin architecture and in patterns of gene expression. We believe that the studies will not only elucidate the complex, yet highly reproducible processes ...
The axons of motoneurons, neurons that make synaptic contacts with muscle cells, and the axons of the neurons that send sensory information to the central nervous system, leave or enter the spinal cord, respectively, as bundles known as nerve roots. There are two types of nerve roots: ventral roots, which leave the spinal cord ventrally and carry motor information to muscle cells, and dorsal roots, which enter the spinal cord dorsally, and carry sensory information from most parts of the body. Furthermore, some axons from sympathetic preganglionar neurons (thoracic and lumbar levels: T1 to L3) or from parasympathetic neurons (sacral level: S2-S4), belonging to the autonomous nervous system, also travel through the ventral nerve roots. Both ventral and dorsal roots are distributed at more or less regular intervals along the spinal cord. They are sorted in couples, that is, two ventral roots and two dorsal roots are located at the same level of the spinal cord (one ventral root and one dorsal ...
Background: Secretagogin (Scgn), a member of the EF-hand calcium-binding protein (CaBP) superfamily, has recently been found in subsets of developing and adult neurons. Here, we have analyzed the expression of Scgn in dorsal root ganglia (DRGs) and trigeminal ganglia (TGs), and in spinal cord of mouse at the mRNA and protein levels, and in comparison to the well-known CaBPs, calbindin D-28k, parvalbumin and calretinin. Rat DRGs, TGs and spinal cord, as well as human DRGs and spinal cord were used to reveal phylogenetic variations. Results: We found Scgn mRNA expressed in mouse and human DRGs and in mouse ventral spinal cord. Our immunohistochemical data showed a complementary distribution of Scgn and the three CaBPs in mouse DRG neurons and spinal cord. Scgn was expressed in similar to 7% of all mouse DRG neuron profiles, mainly small ones and almost exclusively co-localized with calcitonin gene-related peptide (CGRP). This co-localization was also seen in human, but not in rat DRGs. Scgn could ...

On average, there are 55,000 myelinated and 110,000 unmyelinated axons in the lateral funiculus and 26,000 myelinated and 9,000 unmyelinated axons in the ventral funiculus at these levels. These figures combined with data from earlier studies of the posterior funiculus and the tract of Lissauer give approximate figures of 88,500 myelinated and 131,500 unmyelinated axons for the entire white matter of one side of the rat sacral spinal cord. Thus unmyelinated axons predominate in the white matter of the rat sacral spinal cord. The majority of axons, particularly the unmyelinated axons, are located in the lateral funiculus. The axons are concentrated in the dorsolateral part of the lateral funiculus, and ...
TY - JOUR. T1 - Effect of aminophylline and isoproterenol on spinal cord blood flow after impact injury. AU - Dow-Edwards, D.. AU - DeCrescito, V.. AU - Tomasula, J. J.. AU - Flamm, Eugene S.. PY - 1980. Y1 - 1980. N2 - A study of the effects of spinal cord injury upon spinal cord blood flow was carried out in cats. A 400 g-cm impact produced an overall reduction in spinal cord blood flow of 24% in the white matter and 30% in the gray matter, as determined by 14C-antipyrine autoradiography. At the level of the injury, white-matter flow was 8.1 ml/100 g/min, g/min, a reduction of 49%, and in the gray matter, 12.5 ml/100 g/min, a reduction of 76%. Treatment with aminophylline and isoproterenol improved the overall blood flow in the spinal cord. At the level of the injury, white-matter flow after this treatment was no longer significantly different from control values. The gray-matter flow remained decreased to 26.2 ml/100 g/min, a reduction of only 47%. It is proposed that aminophylline and ...
Introduction: The rate of spinal cord infarction associated with repair of an aortic aneurysm or dissection is uncertain.. Methods: We identified all adult patients discharged from nonfederal acute care hospitals in California, New York, and Florida who underwent surgical or endovascular repair of a thoracic or abdominal aortic aneurysm or dissection between 2005 and 2013. Our outcome was a spinal cord infarction (ICD9-CM codes: 336.1 or 344.1-5) occurring during the index hospitalization for aortic repair. Patients with a spinal cord infarction prior to the hospitalization for aortic repair were excluded. Descriptive statistics with exact confidence intervals (CIs) were used to report crude rates of spinal cord infarction in patients with repair of ruptured aortic aneurysm or dissection and in patients with repair of unruptured aneurysm. In a secondary analysis, we evaluated the rate of spinal cord infarction in these groups by treatment approach - surgical versus endovascular.. Results: We ...

Spinal cord injuries can be life altering and devastating. Spinal cord injuries can occur as the result of a motor vehicle accident or other compensable accident, and may not always be apparent immediately following injury.. Traumatic spinal cord damage (damage caused by injury), can occur instantly or it can develop over time. A spinal cord injury typically results in full or partial loss of sensation and bodily function below the site of the injury. Some spinal cord injuries are obvious, as in paraplegia (loss of function involving the upper limbs) and quadriplegia (loss of function involving all four limbs), and some might be less obvious, at least initially, and may progress over time. A traumatic spinal cord injury might even be diagnosed as whiplash or other soft tissue injury early on. Damage to the spinal cord can be caused by compression, bruising, tearing or severing of the spinal cord, all of which can result from the forces involved in a motor vehicle accident, including whiplash ...
Traumatic spinal cord injury (SCI) causes serious disruption of neuronal circuits that leads to motor functional deficits. Regeneration of disrupted circuits back to their original target is necessary for the restoration of function after SCI, but the pathophysiological condition of the caudal spinal cord has not been sufficiently studied. Here we investigated the histological and biological changes in the distal part of the injured spinal cord, using a mice model of complete thoracic SCI in the chronic stage (3 months after injury). Atrophic changes were widely observed in the injured spinal cord both rostral and caudal to the lesion, but the decrease in area was mainly in the white matter in the rostral spinal cord while both the white and gray matter decreased in the caudal spinal cord. The number of the motor neurons was maintained in the chronic phase of injury, but the number of presynaptic boutons decreased in the lumbar motor neurons caudal to the lesion. Using laser microdissection, to
BACKGROUND. Spinal cord tumors are rare in cats and dogs. The most common spinal cord tumors are lymphoma in cats and meningioma in dogs. The majority of cats with spinal lymphoma are FeLV positive. Other spinal cord tumors include intradural-extramedullary spinal cord tumor of young dogs (also known as nephroblastoma and ependymoma) and glial tumors such as astrocytomas, oligodendroglioma, and choroid plexus tumors. The spinal cord can also be affected by extension of peripheral nerve tumors into the spinal canal. Spinal cord tumors cause neurologic dysfunction with clinical signs being dependent on their location along the spinal cord. Metastasis is rare.. DIAGNOSIS. Survey and contrast radiographs (myelogram) are important to rule out other causes of neurologic disease, such as intervertebral disk disease and vertebral tumors. The contrast pattern on the myelogram is used to classify spinal cord tumors as extradural, intradural-extramedullary, or intramedullary. Meningiomas and peripheral ...
Spinal cord injury is damage to the spinal cord, which is the bundle of nerves housed within the spinal column (commonly known as the backbone). The spinal cord carries messages between the brain and body, and injury to the spinal cord may result in full or partial loss of motor control and sensation.. Spinal cord injuries may leave victims paralyzed in the lower parts of the body (paraplegic) or in all four limbs (quadriplegic). Because the spinal cord is responsible for a range of bodily functions (breathing, body temperature, bladder, and sexual function), accident victims can suffer a broad range of permanent and serious health problems. And with these physical challenges often come emotional and psychological problems because many men and women with some degree of paralysis dont feel whole, and they feel as though their lives will never be the same.. Spinal cord injuries, much like traumatic brain injuries, often change people lives forever in ways they never dreamed of, and many spinal ...

We tested whether MCI-186, which is useful for treating ischemic damage in the brain, can protect against ischemic spinal cord damage. Methods: After induction of ischemia, MCI-186 or vehicle was injected intravenously. Cell damage was analyzed by observing the function of the lower limbs and by counting the number of motor neurons. To investigate the mechanism by which MCI-186 prevents ischemic spinal cord damage, we observed the immunoreactivity of Cu/Zn superoxide dismutase, neuronal nitric oxide synthase, and endothelial nitric oxide synthase. ...
Spinal Cord Injury (SCI) is damage to the spinal cord that results in a loss of function such as mobility or feeling. Frequent causes of damage are trauma (car accident, gunshot, sports accidents, falls, etc.) or disease (polio, spina bifida, spinal tumours, etc.). The spinal cord does not have to be severed in order for a loss of functioning to occur. In fact, in most people with SCI, the spinal cord is intact, but the damage to it results in loss of functioning. SCI is very different from other back injuries such as ruptured disks, or pinched nerves.. A person can break their back or neck yet not sustain a spinal cord injury if only the bones around the spinal cord (the vertebrae) are damaged, but the spinal cord is not affected. In these situations, the individual may not experience paralysis after the bones are stabilized.. What is the spinal cord and the vertebra? The spinal cord is about 18 inches long and extends from the base of the brain, down the middle of the back, to about the ...

The protein kinase inhibitor K-252a increased choline acetyltransferase (ChAT) activity in rat embryonic spinal cord cultures in a dose-dependent manner (EC50 of approximately 100 nM) with maximal stimulatory activity at 300 nM resulting in as much as a fourfold increase. A single application of K-252a completely prevented the marked decline in ChAT activity occurring over a 5-day period following culture initiation. Of 11 kinase inhibitors, only the structurally related inhibitor staurosporine also increased ChAT activity (EC50 of approximately 0.5 nM). Effective concentrations of K-252a were not cytotoxic or mitogenic and did not alter the total protein content of treated cultures. Insulin-like growth factor I, basic fibroblast growth factor, ciliary neurotrophic factor, and leukemia inhibitory factor yielded dose-dependent increases in ChAT activity in spinal cord cultures. The combination of K-252a with insulin-like growth factor-I or basic fibroblast growth factor increased ChAT activity up ...
Clonus is a reflex typically caused by sudden, passive stretch of a muscle. For example, when you lift your leg and place your foot back on the ground, the slight upwards stretch of the ankle can trigger clonus. Clonus is most common in the ankles and feet. However, depending on your level of injury, it can also occur in the knees, calves, wrists, triceps, and biceps.. After a spinal cord injury, you might have spinal shock, which causes temporary loss of all reflexes below your level of injury. Once spinal cord inflammation starts to stabilize and swelling dies down, some reflexes may slowly start to return. The spinal cord can act independently from the brain. When messages from the brain cant reach the muscles due to spinal cord damage, your spinal cord may become hypersensitive and send nerve impulses to the muscles on its own. As a result, you experience two different extremes. Previously limp muscles can become hyperreactive to stimulation, which can cause clonus. ...
Spinal cord stimulation is a procedure that delivers low-level electrical signals to the spinal cord to block pain signals from reaching the brain.. Spinal cord stimulators consist of thin wires and a small, pacemaker-like battery pack. The electrodes are placed in between the spinal cord and the vertebrae, and the generator is placed under the skin, typically near the buttocks or abdomen. Spinal cord stimulators enable patients to send the electrical impulses with a remote control when they feel pain. Both the remote control and its antenna are outside the body.. Common biological complications include infection and pain over the implant. However, Spinal cord neurostimulation techniques are safe and reversible therapies.. The surgery for the implant typically takes up to 2 hours to complete.. SCS is deemed successful if the pain is reduced by at least half. Studies show good to excellent long-term relief in 50 to 80 per cent of patients suffering from chronic pain.. The implants cost about USD ...
We have shown previously that mats made from the glycoprotein fibronectin are permissive for axonal growth when implanted into the injured spinal cord. Recent evidence has indicated that fibronectin and its peptides also have neuroprotective effects in the CNS. We have therefore examined the neuroprotective effects of fibronectin applied to a spinal cord injury site. Adult rats with fibronectin mats implanted into a spinal cord lesion cavity had decreased apoptosis in the intact adjoining spinal cord tissue at 1 and 3 days post-injury compared to rats that had gelfoam implanted into the lesion cavity. Rats with fibronectin mat implants also showed enhanced hindlimb locomotor performance for the first 3 weeks post-surgery compared to control animals. To further examine the neuroprotective potential of fibronectin following spinal cord injury, we examined the effects of placing fibronectin mats over the site of a spinal cord hemisection or of delivering a solution derived from a dissolved ...

Director, Spinal Cord Injury Rehabilitation Program. People often ask me when or if there will ever be a cure for spinal cord injury. Although there are many differing opinions about this, I am confident there will be a cure in my lifetime. In the meantime, anyone with a spinal cord injury should have a long-term plan for their treatment and care.. The number of spinal cord injuries per year has remained fairly stable over the last two decades, with nearly 12,000 occurring each year mostly from sports injuries, car accidents and other forms of traumatic injury. Currently in the United States there are approximately 200,000 people are living with spinal cord injuries or spinal dysfunction. With todays advanced medical treatments, more spinal cord injury patients survive the trauma compared to just a few decades ago. This positive shift in mortality rate underlines the great importance of initial acute treatment and follow up rehabilitation.. Treatment for spinal cord injuries can be divided into ...
The present study investigated the projections of the gigantocellular reticular nucleus (Gi) and its neighbors-the dorsal paragigantocellular reticular nucleus (DPGi), the alpha/ventral part of the gigantocellular reticular nucleus (GiA/V), and the lateral paragigantocellular reticular nucleus (LPGi)-to the mouse spinal cord by injecting the anterograde tracer biotinylated dextran amine (BDA) into the Gi, DPGi, GiA/GiV, and LPGi. The Gi projected to the entire spinal cord bilaterally with an ipsilateral predominance. Its fibers traveled in both the ventral and lateral funiculi with a greater presence in the ventral funiculus. As the fibers descended in the spinal cord, their density in the lateral funiculus increased. The terminals were present mainly in laminae 7-10 with a dorsolateral expansion caudally. In the lumbar and sacral cord, a considerable number of terminals were also present in laminae 5 and 6. Contralateral fibers shared a similar pattern to their ipsilateral counterparts and some ...
The results of spinal cord stimulation depend on the severity of your condition, your level of health, physical activity, among other factors. SCS does not intend to cure the condition leading to pain, rather it leads to successful pain management and successful outcomes are generally considered to be a reduction of pain by at least half. As this is a non-invasive procedure, there are no risks or general complications. SCS may be used in conjunction with medications as prescribed by Dr. Ali.. Common conditions that have been treated with spinal cord stimulation include, Sciatica or chronic leg or arm pain, spinal cord injuries, inflammation of the spinal nerves, pain from failed back surgeries, and others.. If you would like to schedule a consultation or find out more about spinal cord stimulation, please feel free to reach out to us and we will be more than happy to assist you.. ...
If the tumor is malignant and has spread into the spine from other parts of the body, treatment depends on the type of cancer it is. Surgery is usually the first step in treating cancerous and noncancerous tumors outside the spinalcord. Tumors inside the spinal cord may not be able to be completely removedwith surgery. If they cant be removed, radiation and chemotherapy treatments may ease symptoms. Treatment also may include pain relievers and drugs to lessen swelling around the tumor, and relieve pressure on the spinal cord.. Early diagnosis and treatment can produce a higher success rate. Long-term survival depends on the tumors type, location, and size. Surgery to remove thebone around the spinal cord can ease pressure on the spinal nerves and nervepathways, which will usually ease pain and other symptoms; however, it may make walking more difficult. Physical therapy and rehabilitation may help.. Since spinal cord tumors usually are caused by spread of cancer that has first appeared ...
After suffering with chronic back pain that cannot be alleviated with any other treatment, patients can be offered spinal cord stimulators. How does spinal cord stimulation work? Spinal cord stimulation is a procedure in which a device is implanted into the patients body to deliver electrical signals to the spinal cord (or to nerves) to block pain signals from getting to the brain - this effectively eliminates chronic pain that otherwise could not be addressed.. Spinal cord stimulation is typically a last resort for those suffering with chronic back pain. Although the procedure could work for some patients, other patients are likely to suffer irreversible harm associated with the procedure - paralysis being among the most severe. Although there are a number of risks associated with surgical procedures (like infection and bleeding), paralysis is not among the risks that are typically associated with the procedure; rather, paralysis typically occurs as a direct result of medical ...

OVERVIEW. Spinal cord stimulation (SCS) is a pain-relief technique that delivers a low-voltage electrical current continuously to the spinal cord to block the sensation of pain. SCS is the most commonly used implantable neurostimulator treatment for the management of chronic pain of the trunk and limbs (back, legs and arms).. WHAT IS CHRONIC PAIN?. Chronic pain is long standing pain that persists beyond the usual recovery period or that accompanies a chronic health condition. Because this pain is not protective and is not a result of an ongoing injury, it is referred to as "pathological" and is therefore treated as a condition, not as a symptom. Chronic pain may prevent people from working, eating properly, participating in physical activity or enjoying Life.. WHAT IS A SPINAL CORD STIMULATOR?. A Spinal Cord Stimulator (SCS) is a device surgically placed under the skin that sends mild electric current to the spinal cord. A small wire carries the current from a pulse generator to the ...
The purpose of this study was to study the acute phase effects of adenosine triphosphate (ATP)MgCl2 on experimental spinal cord clip compression injury. Spinal cord clip compression injury was performed on 36 albino Wistar rats. The rats were divided into five groups. T4-T8 total laminectomy was performed on all rats. Group 1: sham-operated group. Group 2: clip compression group. In group 3, ATP-MgCl2 (100 mumol/kg) was given 2 min before the clip compression injury. In group 4, ATP-MgCl2 (100 mumol/kg) was given 5 min after the clip compression injury. In group 5, ATP MgCl2 (100 mumol/kg) was administered 8 h after the injury. The spinal cords were excised for a length of 2 cm and deep frozen at -76degreesC. Tissue malondialdehyde (NIDA) levels were used to determine the effects of ATP-MgCl2 on spinal cord lipid peroxidation.. In the groups in which ATP MgCl2 was administered after the clip compression injury (groups 4 and 5), the decrease in spinal cord MDA levels was statistically ...
Any type of spinal cord injury is one that can alter your life in many ways. For this reason, its important to do two things:. - Pay close attention to the health of your spinal cord.. - Receive immediate medical treatment if your spinal cord is injured in any way.. With an incomplete spinal cord injury, its difficult to know what the future will bring. However, there are several things you should know about this:. - Spinal cord injuries that do not cause complete paralysis are those with which there is a greater chance of additional recovery in the future.. - When a person still has sensation in the lower part of his or her body, there is a chance that he or she could experience some muscle recovery.. - The sooner muscles begin to work after an incomplete spinal cord injury, the better chance there is that the person will experience additional recovery, especially as it pertains to walking.. While these are some of the most important facts associated with an incomplete spinal cord injury, ...
Graphic by Frank Jackson III/MEDILL based on data from The Chris and Dana Reeve Foundation, courtesy of the Medill School of Northwestern University. Click on image for larger version.. Direct injury, such as cuts, can occur to the spinal cord from broken vertebrae or foreign fragments entering the spinal cord or surrounding area. Direct damage can also occur if the spinal cord is pulled, pressed sideways or compressed. This may occur if the head, neck or back are pushed back or twisted abnormally during an accident. Bleeding, fluid buildup and swelling can also occur inside or outside the spinal cord. The swelling and buildup of blood or fluid can press on the spinal cord and also damage it.. Spinal cord injury happens to all age groups. Data from the 1970s showed young men from 16 to 30 years old had the highest incidence of traumatic spinal cord injury. The latest data from 2005 shows that the average age at injury is 41 years old. An increase in trauma to middle-aged as well as to the ...
Quantitative MRI techniques have the potential to characterize spinal cord tissue impairments occurring in various pathologies, from both microstructural and functional perspectives. By enabling very high image resolution and enhanced tissue contrast, ultra-high field imaging may offer further opportunities for such characterization. In this study, a multi-parametric high-resolution quantitative MRI protocol is proposed to characterize in vivo the human cervical spinal cord at 7T. Multi-parametric quantitative MRI acquizitions including T1, T2(*) relaxometry mapping and axial diffusion MRI were performed on ten healthy volunteers with a whole-body 7T system using a commercial prototype coil-array dedicated to cervical spinal cord imaging. Automatic cord segmentation and multi-parametric data registration to spinal cord templates enabled robust regional studies within atlas-based WM tracts and GM horns at the C3 cervical level. T1 value, cross-sectional area and GM/WM ratio evolutions along the cervical
Severe spinal cord injury is a very debilitating injury. This report presents information from the Australian Spinal Cord Injury Register on 381 cases from trauma and disease in 2004-05. During the year, 280 new cases of spinal cord injury from traumatic causes were registered in Australia, an age-adjusted incidence rate of 15.4 cases per million population. The most common clinical outcome of spinal cord injury was incomplete tetraplegia. Falling was the most common type of event leading to traumatic spinal cord injury at older ages. The Australian Spinal Cord Injury Register is a collaborative activity of the AIHW National Injury Surveillance Unit and all of the specialist spinal units in Australia.. ...
Effective therapeutic interventions for injuries of the central nervous system such as spinal cord injury are still unavailable, having a great impact on the quality of life of victims and their families, as well as high costs in medical care. Animal models of spinal cord injury are costly, time-consuming and labor-intensive, making them unsuitable for screening large numbers of experimental conditions. Thus, culture models that recapitulate key aspects of neuronal changes in central nervous system injuries are needed to gain further understanding of the pathological and regenerative mechanisms involved, as well as to accelerate the screening of potential therapeutic agents. In this study we differentiated adherent cultures of dissociated human fetal spinal cord neural precursors into postmitotic neurons which we could then detach from culture plates and successfully freeze down in a viable state. When replated in neuronal medium without neurodifferentiating factors, these ready-to-use human spinal cord
Although the spinal cord contains all the circuitry necessary for locomotion, due to the absence of commands from the brain, people with spinal cord injuries are unable to walk. Motor recovery can be partially achieved by strategies or therapies intended to regenerate axons from the brain to the spinal cord. Some of these approaches have reported such promising results in animal models that clinical trials are currently underway. However, a major obstacle to achieving this goal is the lack of identification and characterization of appropriate targets at the brain and spinal cord levels, as well as the lack of knowledge of the mechanisms of plasticity of these targets. Dr. Bretzners project aims to investigate the pathways between the brain and the spinal cord that are important for initiation and modulation of locomotion. This will allow for the identification and characterization of the nervous circuits that need to be repaired in order to improve functional recovery following spinal cord ...

A spinal cord injury is an injury that causes the accident victims spinal cord to sever - either fully or partially - resulting in a limited or permanent inability to function. One of the primary consequences of a spinal cord injury is full or partial paralysis.. Spinal cord injuries often come about when the accident victim strikes his or her neck or back on the ground in an accident. Motorcycle and bicycle accident victims are especially prone to spinal cord injuries because the neck and back are not covered by a helmet and are at least partially exposed to the impact.. If you or a loved one suffered a spinal cord injury, an Atlanta spinal injury attorney might be able to help you recover damages. ...
TY - CHAP. T1 - Segmentation. T2 - Spinal Cord Segmentation and A-P Somite Patterning. AU - Cook, G. M.W.. AU - Lewis, K. E.. AU - Keynes, R. J.. PY - 2009/1/1. Y1 - 2009/1/1. N2 - Segmentation is conspicuous in the regular periodic spacing of vertebrate spinal nerves. Segmented spinal cord motor neurons and interneurons may have evolved in early vertebrates alongside the segmented somites. Zebra fish spinal motor neurons are organized segmentally, probably in response to somite-derived signals. In birds and mammals, spinal nerve segmentation is generated by an anterior-posterior somite polarity. Somite segmentation and polarization is established via cyclical Notch/Delta, Wnt, and Fgf signaling, and posterior half-somite cells express contact repellents. These force axons and neural crest cells to migrate in the anterior half-somites, ensuring a proper register between spinal nerves and the segmented vertebral column. Diffusible repellents from surrounding tissues also guide spinal axons in the ...
While the recommendations for spinesurgery in specific cases of acute traumatic spinal cord injury (SCI) are well recognized, there is considerable uncertainty regarding the role of the timing of surgical decompression of the spinal cord in the management of patients with SCI. Given this, we sought to critically review the literature regarding the pre-clinical and clinical evidence on the potential impact of timing of surgicaldecompression of the spinal cord on outcomes after traumatic SCI. The primary literature search was performed using MEDLINE, CINAHL, EMBASE, and Cochrane databases. A secondary search strategy incorporated articles referenced in prior meta-analyses and systematic and nonsystematic review articles. Two reviewers independently assessed every study with regard to eligibility, level of evidence, and studyquality. Of 198 abstracts of pre-clinical studies, 19 experimental studies using animal SCI models fulfilled our inclusion and exclusion criteria. Despite some discrepancies ...

A method and apparatus for repairing a severed spinal cord using natural processes and patients own resources, which includes removing cells from the patient, such as embryonic and somatic cells, and a segment of vein from the patient. The vein segment is used to encase the severed portion of the spinal cord. The cultured cells of the patient are injected into the encasement of vein segment surrounding the severed spinal cord. A chip that can generate a magnetic or electric field is then placed on top of the vein to provide a magnetic or electric field on the severed area of the spinal cord that includes the patients cultured cells. The purpose is to repair spinal cord damage through regeneration using a patients own cells and magnetic or electromagnetic energy.
So how can hESCs be used to treat spinal cord injuries? It comes down to the different types of cells in the spinal cord, and their vital roles in making sure that everything works as it should. The two key cell types are neurons and oligodendrocytes. Neurons transmit information in the spinal cord, while oligodendrocytes protect these neurons. Oligodendrocytes do this mostly by making myelin, which is an insulating material that forms a sheath around part of the neuron (similar to how an electrical wire must be insulated to work properly). When the spinal cord is injured, large numbers of oligodendrocytes die and so the neurons no longer have a protective sheath. The oligodendrocytes can be so damaged, and are so important, that a person can become paralyzed even if the neurons themselves survive. To treat a spinal cord injury, its thought the best approach is to introduce new oligodendrocytes into the damaged spinal cord area.. In 2005, researchers found that hESCs could make oligodendrocyte ...
Glutamergic excitotoxicity has been shown to play a deleterious role in the pathophysiology of spinal cord injury (SCI). The aim of this study was to investigate the neuroprotective effect of dizocilpine maleate, MK801 (2 mg/Kg, 30 min and 6 hours after injury) in a mice model of SCI. The spinal cord trauma was induced by the application of vascular clips to the dura via a four-level T5-T8 laminectomy. Spinal cord injury in mice resulted in severe trauma characterized by edema, neutrophil infiltration and apoptosis. In this study we clearly demonstrated that administration of MK801 attenuated all inflammatory parameters. In fact 24 hours after injury, the degree of spinal cord inflammation and tissue injury (evaluated as histological score), infiltration of neutrophils, NF-κB activation, iNOS, cytokines levels (TNF-α and IL-1β), neurotrophin expression were markedly reduced by MK801 treatment. Moreover, in a separate set of experiments, we have demonstrated that MK801 treatment significantly improved
article{9a61eb3f-8c54-482b-b9ab-17e99c703a0d, abstract = {,p,Monoamine neurotransmitters play an important role in the modulation of sensory, motor and autonomic functions in the spinal cord. Although traditionally it is believed that in mammalian spinal cord, monoamine neurotransmitters mainly originate from the brain, accumulating evidence indicates that especially when the spinal cord is injured, they can also be produced in the spinal cord. In this review, I will present evidence for a possible pathway for two-step synthesis of dopamine and serotonin in the spinal cord. Published data from different sources and unpublished data from my own ongoing projects indicate that monoenzymatic cells expressing aromatic L-amino acid decarboxylase (AADC), tyrosine hydroxylase (TH) or tryptophan hydroxylase (TPH) are present in the spinal cord and that these TH and THP cells often lie in close proximity to AADC cells. Prompted by the above evidence, I hypothesize that dopamine and serotonin could be ...
Supplement The spinal nerve is a nerve that occurs in pairs emerging from the spinal cord. Each pair is attached to the cord by two roots, i.e. the anterior (ventral) and posterior (dorsal) roots. Although these two roots unite in the intervertebral foramen they divide again into anterior division (or ventral ramus) and posterior division (or dorsal ramus).1 In humans, there are 31 pairs of spinal nerves emerging from the spinal cord and are grouped based on the corresponding regions of the vertebral column, i.e. cervical spinal nerves, thoracic spinal nerves, lumbar spinal nerves, sacral spinal nerves, and coccygeal spinal nerves. These nerves emerge from the spinal cord through an opening called intervertebral foramen (an opening between adjacent vertebrae of the vertebral column). The cervical spinal nerves are spinal nerves emerging from the cervical region of the spinal cord. They all emerge above their corresponding vertebrae except for the eighth cervical nerve, which emerges below the ...
The spinal cord is covered by three layers of tissue called meninges, the outermost being the dura mater. Although it is a rare complication, the dura may get injured or tear during spinal surgery resulting in the leakage of cerebrospinal fluid (CSF), which normally surrounds the brain and spinal cord. This can cause severe headaches and nausea. Spinal cord injury can occur as a result of trauma, or from arthritis, bleeding, cancer, infection and inflammation. The effects of a spinal cord injury can range from transient deficits to more serious complications such as paralysis or bladder and bowel dysfunction.. During spine surgery, injury may occur due to instruments used to decompress nerves, misplaced implants or grafts, manipulation and ischemia (compromised blood supply). The risk of having a spinal cord injury or a dural tear during spine surgery increases with age as your surgeon needs to cut through toughened spinal ligaments, and in the process, damage the dura. It may also occur in ...
