Diversity in the bodies of thoracic vertebrae. First, the bodies of the thoracic vertebrae vary in size to the degree one is closer to the neck than the other (the first of the figures showing all the bones and the fig. for ch. 14 show this variation of articulation and bulk). The body of the first thoracic vertebra is thus quite smaller than the twelfth. Next, the body of the first, on its superior surface where it is joined to the seventh cervical vertebra, is not entirely flat but swells slightly at each side and subtly imitates the bodies of the cervical vertebrae (h, k, q in fig. 9, ch. 15); but the lower part of this body has a flat surface like the upper and lower surfaces of the bodies of all thoracic vertebrae (A in figs. 1, 2, 3). No lower portion of the body in the thoracic vertebrae is in fact extended even the least bit in a long downward slope or ends in a depression of the body of the next vertebra, as do the cervical vertebrae (r in fig. 8 and z in fig. 9, ch. 15). Yet Galen ...
The choice of treatment for thoracolumbar burst fractures remains controversial. The ideal operative approaches are also disputed1, 2; however, a common surgical goal is to obtain the most stable fixation with fusion of the fewest segments possible.
Three cases are presented of thoracic radiculopathy related to collapsed thoracic vertebral bodies. In all cases proximal weakness of the legs was present, leading to the diagnosis of myopathy in two cases. Sensory symptoms were present in two cases. In one, anterior thigh paresthesias lead to a diagnosis of meralgia paresthetica. This diagnostic entity must be remembered if appropriate corroborative tests are to be performed. In cases of trauma this diagnosis should be considered if thoracic vertebral collapse is present. Conversely, an evaluation of proximal weakness should include a review of thoracic radiographs for vertebral collapse, especially in the presence of sensory findings in the lower abdominal or proximal thigh region.. ...
The spine consists of three vertebral columns, including the cervical vertebrae, lumbar vertebrae, and thoracic vertebrae. The cervical vertebrae are located in the neck. The lowest portion of the spine consists of the lumbar vertebrae. Between the cervical vertebrae and the lumbar vertebrae are the thoracic vertebrae. The 12 thoracic
Continued From Above... Its structure is similar to the other thoracic vertebrae, with a large column of bone known as the centrum (or vertebral body) forming its anterior structure and a thin ring of bone known as the vertebral arch forming its posterior structure. The vertebral body is larger and wider in T12 than in the other thoracic vertebrae and more closely resembles the vertebral bodies of the lumbar vertebrae. It is flat on top and bottom, convex anteriorly, and slightly concave posteriorly. Most of the osseous tissue of T12 is contained within the centrum, which serves to support the bodys weight. A pair of intervertebral disks made of tough fibrocartilage connects the vertebral body of T12 to those of its neighboring vertebrae. Each rubbery intervertebral disk provides a slightly flexible connection between the vertebral bodies and acts as a shock absorber to prevent collisions between the vertebrae.. The vertebral arch of T12 is thicker and stronger than its counterparts in the ...

Thoracic and lumbar fractures represent nearly 90% of traumatic spine injuries. Thoracolumbar region is susceptible to injury because of its location between the stiff kyphotic thoracic spine and the mobile lordotic lumbar region. To compare between short-segment fixation with screws into index level and long-segment fixation in maintaining angle of correction and pain. A prospective study included 91 patients, who had single-level thoracolumbar fracture with Cobbs angle ≤ 25° and underwent posterior fixation. Forty-four patients underwent short-segment fixation with screws into the index level, and 47 patients underwent long-segment fixation with skipped index level. The angle of correction, pain, and neurological state were regularly assessed. Forty-four patients (48.35%) had short segment and 47 (51.65%) had long-segment fixation. In the short segment group, the pre-operative mean Cobbs angle was 19.34° ± 3.63° and the angle of correction was 8.14° ± 1.9° after 1 year, while in the long

This is a retrospective study of the use of parallel endplate osteotomy (PEO) for correction of severe rigid thoracolumbar spine deformity. From July 2016 to January 2019, 12 patients with severe rigid thoracolumbar spine deformity underwent PEO on T12 or L1 vertebrae were studied. Following PEO at T12 or L1, the mean kyphosis and scoliosis correction rates reached 77.0 ± 8.9% and 75.5 ± 8.0%, respectively and the intraoperative estimated blood loss was 1950 ± 1050 mL, and the mean operative time was 6.98 ± 4.02 h. The SF-36 scores of physical function, role-physical, bodily pain, general health, vitality, social function, role-emotional and mental health changed from 63 ± 28, 50 ± 25, 50 ± 30, 34 ± 19, 53 ± 28, 45 ± 30, 30 ± 36 and 54 ± 18 at baseline to 83 ± 18, 69 ± 19, 72 ± 12, 66 ± 21, 75 ± 15, 72 ± 22, 66 ± 34 and 76 ± 12 at 1 year postoperatively, 83 ± 8, 68 ± 32, 83 ± 17, 73 ± 17, 82 ± 18, 76 ± 26, 70 ± 37 and 88 ± 12 at 18 months postoperatively, 86 ± 6, 83 ± 33,
In the thoracic region the intervertebral discs are relatively thin with respect to the vertebral bodies, and together with the presence of the ribs and sternum, their movement is limited. The orientation of the articular processes of the thoracic vertebrae, which lie on the arc of a circle with its centre close to the anterior part of the vertebral body, permits flexion, extension, lateral flexion and rotation. However, the inferior processes of the 12th thoracic vertebra resemble those of the lumbar region and therefore movements at the thoracolumbar junction are similar to those between lumbar vertebrae.. Flexion and extension The combined range of flexion and extension in the thoracic part of the vertebral column is between 50° and 70°, with extension being much more limited than flexion. Flexion is much freer in the lower half of the region as the lower ribs tend to be longer and more flexible because of their longer costal cartilages.. In flexion the inferior articular processes of the ...

In physical therapy school, the thoracic spine is often glossed over during the musculoskeletal courses. This may be due to the low incidence and prevalence of thoracic spine pain. The incidence of thoracic spine pain is only ~15-19% across the population. This is relatively low ​compared to lumbar spine pain, which has an 80% prevalence in adults. Additionally, physical therapy schools may choose to emphasize the non-musculoskeletal diagnosis that are important in the thoracic spine. Since many organs are housed in the thoracic cavity, hours are spent on non-musculoskeletal diagnosis. For example, if a patient presents with thoracic spine pain, it is more important to rule-out a myocardial infarction than a thoracic facet restriction. Regardless, there is a gap in students knowledge regarding thoracic spine anatomy and biomechanics, mobility assessment, and differential diagnosis ...

The lack of a functional Hoxc10 homeobox causes several homeotic transformations in the axial skeleton (Table 1, Figures 3 and 4). Wild-type C57Bl/6 mice typically have 30 precaudal vertebrae, with the more caudal vertebrae organized in T13L6S4 pattern, with thirteen thoracic vertebrae, six lumbar vertebrae and four sacral vertebrae [refs]. Eighty percent of the wild-type mice examined in this study exhibited this pattern, with the remainder of the animals showing some mild variation in the shape of the L1, L6, or S1 segments; these types of variations are within the range of normal [ref]. Hoxc10 mutant mice also have 30 precaudal vertebrae, but the patterning of the vertebral column is altered. Most Hoxc10 mutant mice (33 of 34 examined) show a partial to complete transformation of the thirteenth thoracic vertebrae, precaudal vertebra 20 (PC20) into a lumbar identity, typified by the reduction or complete loss of the thirteenth rib. By definition, thoracic vertebrae are those vertebrae with ...

By: Dr. David Tiberio, Gray Institute. The thoracic spine is the spinal region that has the most vertebrae, and therefore the most joints. The thoracic spine has a lot of motion in each of the three planes. The motion in three planes can be combined in a variety of ways to contribute to the functional success of purposeful movements of the arms, legs, and head. The motions in the frontal and transverse planes have been described as linked or coupled together, but all combinations including the sagittal plane are needed.. Anatomy separates the thoracic spine from the cervical spine above and the lumbar spine below. However during global functional movements, the spine becomes a single unit linked to all four extremities. The importance of the thoracic spine becomes evident when we recognize even a few of the truths of Chain Reaction movements:. Any appreciable movement of the head (driven by the eyes) in any of the six directions will involve the upper thoracic region. All shoulder motions ...

Its articular facets with the ribs make a transition from the ventral body, as in the T1-9 vertebrae, to the pedicle so that the head of the rib articulates more closely with the vertebral arch than with the ventral body. At the T10 vertebra, the spinous process begins to become increasingly horizontal as the spinal column descends toward the lumbar vertebrae.. ...

Minimally invasive methods and devices for introducing a spinal fixation element into a surgical site in a patients spinal column are provided. In general, the method involves advancing a spinal fixation element in a first, lengthwise orientation along a pathway extending from a minimally invasive percutaneous incision to a spinal anchor site. As the spinal fixation element approaches the spinal anchor site, the fixation element can be manipulated to extend in a second orientation, which is preferably substantially transverse to the first orientation, to position the fixation element in relation to one or more spinal anchors.

Introduction: Posterior surgical stabilization is commonly indicated for unstable thoracolumbar fractures. Short segment stabilization has the advantage of preserving mobile segments and reducing excessive loads on the adjacent discs but is not without complications. Rod migration is an extremely rare complication after thoracolumbar fracture fixation and can lead to catastrophic visceral and vascular injuries. To the best of our knowledge, this is the first case report of a surgically managed distant rod migration into the posterior sacrum and pelvis after a posterior thoracolumbar trauma fixation. Case Report: A 25-year-old male patient presented to our center with complaints of the right buttock and groin pain for 8weeks. He had a history of an unstable thoracolumbar fracture treated by a short segment posterior stabilization 5years back. On examination and investigations, we found that the right-sided rod migrated into the posterior sacrum and partly into the pelvis. The fracture had united well in
Compression studies were conducted on the ligamentous thoracolumbar spines of fresh human male cadavers. For comparison, forces were applied to the posterior upper thoracic region of intact seated cadavers. Since this type of injury routinely involves ligament failure and vertebral body wedge compression fractures, studies were conducted on single vertebral bodies and isolated ligaments. Similar studies were conducted in isolated monkey ligaments. The intact and ligamentous thoracolumbar spines failed predominately in the region of the thoracolumbar junction at forces from 1113-5110 N. For both the human and monkey cadavers, the anterior longitudinal ligament was the strongest. The human ligaments were 2-5 times stronger than those of the monkey ...
This study compares the fatigue failure of a tapered titanium-rod construct against two connected titanium rods (domino construct) across the cervicothoracic junction. All testing was carried out in a simulated flexion-extension plane. The 3.5-mm/6.0-mm tapered titanium rod and the 3.5-mm titanium rod, connected to a 6.0-mm titanium rod with a connector, were compared for their fatigue failures. Six specimens of each construct were tested in a cantilever displacement control method using 6 different amplitudes. Each specimen was cycled to failure or to 2.5 million cycles (run out) at 10 Hz. Failure was defined as rod fracture. The domino construct reached the test limit of 2.5 million cycles at± 0.45 mm (72 N) but failed in all the other tested amplitudes. The tapered rod construct reached the test run out limit of 2.5 million cycles at higher amplitudes than the domino construct at ± 0.9 mm and failed in all the other tested amplitudes. The study showed that the tapered-rod construct across ...

The mean operative duration was 205.4 min (range 115-375 min), with an average blood loss of 488.5 mL (range 215-880 mL). Radiographical and clinical outcomes were assessed after a mean of 61.4 months of follow-up. The VAS back pain and ASQoL scores improved significantly in all patients (7.52 ± 1.31 vs. 1.70 ± 0.70, t = 18.30, P < 0.001; 13.87 ± 1.89 vs. 7.22 ± 1.24, t = 18.53, P < 0.001, respectively). The thoracolumbar kyphosis (TLK) changed from 40.03 ± 17.61° pre-operatively to 13.86 ± 6.65° post-operatively, and 28.45 ± 6.63° at final follow-up (F = 57.54, P < 0.001), the thoracic kyphosis (TK) changed from 52.30 ± 17.62° pre-operatively to 27.76 ± 6.50° post-operatively, and 28.45 ± 6.63° at final follow-up (F = 57.29, P < 0.001), and lumbar lordosis (LL) changed from -29.56 ± 9.73° pre-operatively to -20.58 ± 9.71° post-operatively, and -20.73 ± 10.27° at final follow-up (F = 42.50, P < 0.001).

In this series of adolescent idiopathic scoliosis double curves we found postoperative transverse plane pelvic rotation increase (TPPRI) in 7 of 17, with resolution in 5 of the 7. Two of the variables studied were significantly associated with TPPRI. They were the addition of un-instrumented sequential anterior thoracolumbar/lumbar discectomy and arthrodesis and increased preoperative tilt of the vertebra below the lower instrumented vertebra. The occurrence of TPPRI and whether or not it persisted did not affect clinical outcome.. We interpret postoperative TPPRI to be a decompensation caused by extension of the corrective thoracolumbar/lumbar rotational load into the lumbosacral hemicurve below. This is supported by our finding that postoperatively the rotation of the vertebra below the lower instrumented vertebra in the direction of the thoracolumbar/lumbar curve (counterclockwise) had not changed in the no-TPPRI group, whereas in the TPPRI group it had decreased significantly, from 6° to ...

The importance of sagittal alignment in healthy individuals and in reconstructive spinal surgery has been studied over the last 15 years. The aim of the present study was to assess the long-term effects of abnormal sagittal alignment on hardware after posterior thoracolumbar spinal fusion. Patients who had undergone revision surgery (revision cohort, n = 34) due to breakage of their implants were compared retrospectively with patients who had intact implants at the final follow-up investigation after a long posterior thoracolumbar and/or lumbar spinal fusion (control cohort, n = 22). Clinical data and radiological parameters including the sagittal vertical axis (SVA), pelvic incidence (PI), lordosis gap (LG), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), and the femoral obliquity angle (FOA) were assessed on full-spine lateral radiographs obtained in regular standing position. Data were analysed using descriptive statistics, parametric and non-parametric inferential

Context The Thoracolumbar Injury Classification Program (TLICS) has been described to greatly help doctors in the decision-making procedure for thoracolumbar spinal trauma. and with AO type A accidents are treated. AO type B and C accidents surgically are maintained, in regards to to neurological position. Sufferers with cauda equina or incomplete accidents received an increased intensity rating also. Controversies remain regarding the administration of unpredictable burst fractures without neurological position. The role from the posterior ligamentous complicated position as well as the magnetic resonance imaging in the decision-making procedure require more clinical evidence. stated that the ligamentous structures in AO type A fractures, compression and burst fractures, are intact. However, the literature widely defines burst fractures wherein the posterior ligamentous structures are thought to be injured (i.e. unstable burst fractures).4 For our study, we assume that type A injuries can have ...

AU - Pirris, Stephen. AU - Reyes, Phillip M.. AU - Newcomb, Anna G U S. AU - Mendes, George A C. AU - Kalb, Samuel. AU - Theodore, Nicholas. AU - Crawford, Neil R.. PY - 2016/8/1. Y1 - 2016/8/1. N2 - OBJECTIVE: Transvertebral screws provide stability in thoracic spinal fixation surgeries, with their use mainly limited to patients who require a pedicle screw salvage technique. However, the biomechanical impact of transvertebral screws alone, when they are inserted across 2 vertebral bodies, has not been studied. In this study, the authors assessed the stability offered by a transvertebral screw construct for posterior instrumentation and compared its biomechanical performance to that of standard bilateral pedicle screw and rod (PSR) fixation. METHODS: Fourteen fresh human cadaveric thoracic spine segments ...
Symptomatic thoracic disc herniation is a relatively uncommon clinical entity and surgical intervention on thoracic discs is even more rare.. Given the unique surgical challenges presented by thoracic spine anatomy, despite described innumerable discectomy techniques, none of them has been accepted universally. The incidence of thoracic disc herniations is 1/1,000 to 1/1,000,000. 0.15% to 4% of all surgical disc procedures are in the thoracic region. 70% occur below T7, most common at T9-12.. Minimally invasive techniques brought a paradigm shift in the management of cervical/lumbar spinal conditions and similar techniques have been extrapolated to the thoracic region as well.. Traditional and microsurgical approaches are associated with significant muscle and bony resections. ...

The thoracic spine contains 12 medium sized vertebrae all of which form articulations (joints) with 2 opposing ribs. Like the other spinal vertebrae, the thoracic vertebrae act as attachments for muscles and ligaments in the mid spine and also encase and protect the median aspect of the spinal cord and thoracic nerve roots. Because the thoracic vertebrae form relatively strong articulations with the ribs, the mobility of the thoracic spine is less than that of the cervical and lumbar spines. However, this same characteristic also protects the thoracic spinal discs and facet joints from the wear and tear experienced by these structures in the other areas of the spine. Common vertebral problems in the thoracic spine include vertebral subluxations, a condition where the vertebrae of the thoracic spine become statically misaligned and/or function abnormally resulting in pain, muscle spasm, and sometime nerve malfunction. ...

TY - CHAP. T1 - Thoracic Spine Stabilization. AU - Kalyvas, J.. AU - Theodore, Nicholas. PY - 2014/1/1. Y1 - 2014/1/1. N2 - Thoracic spine instability is unusual because of the anatomical support provided by the rib cage. Nevertheless, it does result from a myriad of causes and may place the spinal cord and nerve roots at risk with potentially devastating neurological consequences. The field of surgical stabilization of the thoracic spine has evolved in terms of its anatomical approaches, instrumentation, techniques for arthrodesis, and intraoperative evaluation, all of which have led to better patient outcomes. Selecting appropriate patients and surgical treatments as well as appropriately managing these patients before and after surgery is paramount to success..

TY - JOUR. T1 - Safety of supplemental endplate screws in thoracic pedicle hook fixation. AU - Cohen-Gadol, Aaron A.. AU - Dekutoski, Mark B.. AU - Kim, Choll W.. AU - Quast, Lynn M.. AU - Krauss, William E.. PY - 2003/1/1. Y1 - 2003/1/1. N2 - Object. The AO Universal Spine System thoracic pedicle hook design includes a fixation screw that passes obliquely through the inferior facet into the pedicle to engage in the posterior portion of the superior vertebral body endplate. This endplate screw provides additional purchase at the hook-bone interface. To determine the safety of this fixation system the authors reviewed the operative notes, radiographs, and outcomes of patients who underwent placement of endplate screws. Methods. Thirty-six patients (16 male and 20 female patients) who required posterior thoracic instrumentation for spinal deformity (11 cases), neoplasm (15 cases), and traumatic injury (10 cases) were included in this study. One hundred sixty-four endplate screws were placed (mean ...
In Europe there is a 3-fold variation, according to geographical center, in risk of vertebral deformity in men and women over the age of 50. We investigated the relationship between bone density, as assessed by dual-energy X-ray absorptiometry (DEXA) of the spine and hip and prevalent vertebral deformities in 13 of the 36 centers participating in the European Vertebral Osteoporosis Study (EVOS). Each center recruited an age-stratified sample of men and women aged 50 years and over, and of those who agreed to densitometry, 288/2088 women and 233/1908 men were found to have one or more deformities of the vertebrae between T4 and L4 as assessed by the McCloskey algorithm. DEXA was in each case performed on L2-L4, the proximal femur, or both. Bone densitometry results were cross-calibrated between centers using the European Spine Phantom prototype and results expressed as bone mineral density (BMD, g/cm2). In both genders, subjects with deformities involving loss of anterior vertebral body height alone
The pedicles are directed backward and slightly upward, and the inferior vertebral notches are of large size, and deeper than in any other region of the vertebral column. The laminae are broad, thick, and imbricated - that is to say, they overlap those of subjacent vertebrae like tiles on a roof and connect with the pedicles to surround and protect the spinal cord. The intervertebral foramen is small, and circular, with two at each intervertebral level, one for the right and one for the left exiting nerve roots. The vertebral foramen is the large opening posterior to the vertebral body also known as the spinal canal. It contains and protects the spinal cord at the thoracic level. The spinous process is long, triangular on coronal section, directed obliquely downward, arising from the lamina and ending in a tuberculated extremity. These processes overlap from the fifth to the eighth, but are less oblique in direction above and below. The superior articular processes are thin plates of bone ...
Focal vertebral bone density changes were assessed in vertebral computed tomography (CT) images obtained from clinically healthy dogs without diseases that affect bone density. The number, location, and density of lesions were determined. A total of 429 vertebral CT images from 20 dogs were reviewed, and 99 focal vertebral changes were identified in 14 dogs. Focal vertebral bone density changes were mainly found in thoracic vertebrae (29.6%) as hyperattenuating (86.9%) lesions. All focal vertebral changes were observed at the vertebral body, except for a single hyperattenuating change in one thoracic transverse process. Among the hyperattenuating changes, multifocal changes (53.5%) were more common than single changes (46.5%). Most of the hypoattenuating changes were single (92.3%). Eight dogs, 40% of the 20 dogs in the study and 61.6% of the 13 dogs showing focal vertebral changes in the thoracic vertebra, had hyperattenuating changes at the 7th or 8th thoracic vertebra. Our results indicate ...

The orientation of superior articular facets from C3 to S1 carries a functional and clinical significance in normal day-to-day activities of human body. Accurate information about the orientation of articular facets at all levels in human spinal column is not available in literature (Stewart, 1952; Comas, 1960; & Montagu, 1960).. According to the information obtained from the textbooks of anatomy & orthopedics, the articular facets in cervical region are oriented in coronal plane. The articular surfaces of superior facets face upwards & backwards & those of corresponding inferior facets face downwards & forwards. At the cervico-thoracic region and thoracic region, the superior articular facets face posterolaterally. In the thoraco-lumbar and lumbar region, superior articular facets face postero-medially. Similarly, superior articular facets of S1 are directed postero medially.. As part of our present study to measure the sagittal angle of superior articular facets; we searched for an appropriate ...
Twenty-six cases underwent surgery with the remainder managed with bed rest and bracing. Posterior pedicle screw constructs and allograft bone graft were used with a median surgical time of 105 (60 - 270 ± 64) minutes and median blood loss of 400 (150 - 2200 ± 514) ml. An additional corpectomy was performed in one incomplete neurologically impaired patient with an A3 fracture and residual compression.. All 26 surgically treated cases showed fusion at 1 year as assessed on X-ray. This was based on the presence of the bone graft and no sign of failure of instrumentation, i.e. peri-screw lucency or instrumentation breakage.. One case required revision for a misplaced pedicle screw. He developed superficial wound infection which was successfully treated with oral antibiotics. Five patients developed decubitus ulcers as a consequence of their spinal cord injury and suboptimal early care before referral. Six developed pneumonia.. Overall there was modest correction of kyphosis from 25º (3º - 55º ...
