A clinico-pathological study of cervical myelopathy in rheumatoid arthritis: post-mortem analysis of two cases. (1/223)

Two patients who developed cervical myelopathy secondary to rheumatoid arthritis were analyzed post mortem. One patient had anterior atlanto-axial subluxation (AAS) combined with subaxial subluxation (SS), and the other had vertical subluxation (VS) combined with SS. In the patient with AAS, the posterior aspect of the spinal cord demonstrated severe constriction at the C2 segment, which arose from dynamic osseous compression by the C1 posterior arch. A histological cross-section of the spinal cord at the segment was characterized by distinct necrosis in the posterior white columns and the gray matter. In the patient with VS, the upper cervical cord and medulla oblongata showed angulation over the invaginated odontoid process, whereas no significant pathological changes were observed. At the level of SS, the spinal cord was pinched and compressed between the upper corner of the vertebral body and the lower edge of the lamina. Histologically, demyelination and gliosis were observed in the posterior and lateral white columns.  (+info)

Preliminary CT study of C1-C2 rotational mobility in normal subjects. (2/223)

A CT study of normal atlanto-axial (C1-C2) rotary mobility was carried out on ten normal immature subjects. In order to determine the limits of normality, the ten children underwent clinical and radiological examination. The clinical study included checking for objective signs of joint laxity and measurement of rotational neck mobility. The radiological study included standard lateral radiographs in neutral and maximal flexion positions and a CT scan taken in maximal left and right side rotation at the C1-C2 articular processes joint. The superpositioning of the images taken in every rotational direction showed, in all ten children, a wide contact loss between the C1-C2 corresponding facets, ranging from 74 to 85% of the total articular surface. The report on these images, carried out by three independent radiologists, concluded that there was a rotary subluxation in all cases. In the ten children studied, there were no significant differences with regard to neck mobility or laxity signs in clinical or standard X-ray examination. Our results lead us to conclude that, except for complete C1-C2 rotational dislocation with facet interlocking, a CT scan showing a wide - but incomplete - rotational facet displacement is not sufficient to define a status of subluxation. This leads us to perceive that there is a risk of overdiagnosis when evaluating upper cervical spine rotational problems in children. The concept of both rotary C1-C2 fixation and subluxation should be revised.  (+info)

Craniocervical junction synovial cyst associated with atlanto-axial dislocation--case report. (4/223)

A 51-year-old female presented with a rare case of synovial cyst at the cruciate ligament of the odontoid process associated with atlanto-axial dislocation, manifesting as a history of headache and numbness in her left extremities for 5 months, and progressive motor weakness of her left leg. Neuroimaging studies revealed a small cystic lesion behind the dens, which severely compressed the upper cervical cord, and atlanto-axial dislocation. The cyst was successfully removed via the transcondylar approach. C-1 laminectomy and foramen magnum decompression were also performed. Posterior craniocervical fusion was carried out to stabilize the atlanto-axial dislocation. The cyst contained mucinous material. Histological examination detected synovial cells lining the fibrocartilaginous capsule. Synovial cysts of this region do not have typical symptoms or characteristic radiographic features. Careful preoperative evaluation of the symptoms and a less invasive strategy for removal of the cyst are recommended.  (+info)

Transoral decompression for craniovertebral osseous anomalies: perioperative management dilemmas. (5/223)

The surgical outcome of 74 patients, who underwent transoral decompression (TOD) for ventral irreducible craniovertebral junction anomalies between January 1989 to September 1997, was studied to evaluate the perioperative complications and problems encountered. The indications for TOD included irreducible atlantoaxial dislocation (n=24), basilar invagination (n=16), and a combination of both (n=35). Following TOD, occipitocervical stabilization using Jain's technique was carried out in 50 (67.5%) and atlantoaxial fusion using Brooks' construct in 18 (24.3%) patients. The pre- and postoperative radiology was compared to assess the adequacy of decompression and stability. The major morbidity included pharyngeal wound sepsis leading to dehiscence (20.3%) and haemorrhage (4%), valopharyngeal insufficiency (8.1%), CSF leak (6.7%) and inadequate decompression (6.7%). Neurological deterioration occurred transiently in 17 (22.9%) and was sustained in 7 (9.4%) patients. The mortality in six cases was due to operative trauma, exanguination from pharyngeal wound (one each), postoperative instability and inability to be weaned off from the ventilator (two each). Of the 47 (63.5%) patients available at follow up ranging from 3 months to 2 years, 26 (55.3%) showed improvement from their preoperative status while 14 (29.8%) demonstrated stabilization of their neurological deficits. Seven (14.9%) of them deteriorated. Though TOD is logical and effective in relieving ventral compression due to craniovertebral junction anomalies, it carries the formidable risks of instability, incomplete decompression, neurological deterioration, CSF leak, infection and palatopharyngeal dysfunction.  (+info)

Stage-related surgery for cervical spine instability in rheumatoid arthritis. (6/223)

Thirty-six consecutive patients with cervical spine instability due to rheumatoid arthritis (RA) were treated surgically according to a stage-related therapeutic concept. The aim of this study was to investigate the clinical results of these procedures. The initial change in RA of the cervical spine is atlanto-axial instability (AAI) due to incompetence of the cranio-cervical junction ligaments, followed by development of a peridontoid mass of granulation tissue. This results in inflammatory involvement of, and excessive dynamic forces on, the lateral masses of C1 and C2, leading to irreducible atlanto-axial kyphosis (AAK). Finally, cranial settling (CS) accompanied by subaxial subluxation (SAS) occurs. According to these three separate pathological and radiological lesions, the patients were divided into three therapeutic groups. Group I comprised 14 patients with isolated anterior AAI, who were treated by posterior wire fusion. Group II comprised 15 patients with irreducible AAK, who were treated by transoral odontoid resection. The fixation was done using anterior plating according to Harms in combination with posterior wire fusion according to Brooks. Group III comprised seven patients with CS and additional SAS, who were treated with occipito-cervical fusion. Pre- and postoperatively, evaluation was performed using the parameters pain (visual analog scale), range of motion (ROM), subjective improvement and Health Assessment Questionnaire (HAQ). The neurologic deficit was defined according to the classification proposed by Ranawat. Radiographs including lateral flexion and extension views, and MRI scans were obtained. The average clinical and radiographic follow-up of all patients was 50.7 +/- 19.3 months (range 21-96 months). No perioperative fatality occurred. Postoperative pain was significantly relieved in all groups (P < 0.001). In group II a slight improvement in the HAQ was obtained. In groups I and II the ROM of all patients increased significantly (average gain of motion in group I: 11.3 degrees +/- 7. 8 degrees for rotation; 7.8 degrees +/- 5.6 degrees for bending; average gain of motion in group II: 21.5 degrees +/- 14.0 degrees for rotation; 17.2 degrees +/- 5.5 degrees for bending), while it decreased significantly in group III (10.7 degrees +/- 18.1 degrees for rotation; 6.7 degrees +/- 18.5 degrees for bending). Preoperatively 27 patients had a manifest neurologic deficit. At follow-up four patients remained unchanged, all others improved by at least one Ranawat class. All patients, except one, showed solid bony fusion. According to the significantly improved postoperative subjective self-assessment and the clinical and radiological parameters, transoral plate fixation combined with posterior wire fixation after transoral odontoid resection represents an effective reliable and safe procedure for the treatment of irreducible AAK in rheumatoid arthritis.  (+info)

Bow hunter's stroke associated with an aberrant course of the vertebral artery--case report. (7/223)

A 53-year-old male presented with repeated vertebrobasilar insufficiency on turning the head to the left. Angiography revealed severe stenosis of the dominant right vertebral artery at the atlantoaxial level in this position. Decompression surgery for the affected vertebral artery at the transverse foramen of the atlas was planned. However, surgery revealed an aberrant course of the artery, turning at the orifice of the transverse foramen of the atlas and perforating the dura at the occipitoatlantal level after passing through the bony canal of the atlas. Therefore, decompression was performed at the bony canal, which was the contributing site, and the symptoms improved. Bow hunter's stroke may be caused by atlantoaxial arterial anomalies, so accurate preoperative evaluation of the region is necessary to avoid anatomical confusion at surgery.  (+info)

Atlantoaxial dislocation associated with stenosis of canal at atlas. (8/223)

The median atlanto-axial joint is the articulation between the anterior surface of the odontoid process and the posterior surface of the arch of the atlas. The axis of rotation of the joint is vertical and corresponds to the long axis of the odontoid process. The articulation between the odontoid process and the anterior arch of the atlas is a pivot joint with incomplete articular surfaces, since the odontoid process is frequently covered with cartilage upon its anterior surface only, its posterior surface articulating with the transverse ligament of the atlas by a separate joint. Both joints have separate capsules; the posterior one is also regarded as a synovial bursa. The capsule of the median atlanto-axial joint is roomy and relaxed. The articulation is provided with a series of accessory ligaments, which create an extremely firm connection between the head and the first two vertebrae ...
Excessive movement between atlas and axis characterizes anterior atlantoaxial instability. At present, dynamic plain radiographs are the criterion standard in diagnosing AAA subluxation. The atlas slips abnormally forward during flexion because of laxity or rupture of the transverse and alar ligaments. The atlas slips backward when the cervical spine is in the neutral or extension positions. A few studies have reported MR imaging findings of AAA subluxation,8,9 but none has focused on the diagnostic implications of abnormalities in the associated structures or suggested a method to improve the false-negative diagnostic rate in nAAA subluxation patients. To our knowledge, this study is the first attempt to do so.. Routinely cervical spine MR imaging is performed with supine and neutral positioning. With this positioning, gravity pulls the subluxated atlas backward and downgrades the severity of disease on MR images. In our study, x-ray radiographs with neutral positioning yielded a 28% (11 of 40) ...
Instrumented fixation techniques: A number of techniques for atlantoaxial fixation are described including transarticular screw fixation and the C1 lateral mass screws and C2 pedicle screws (Harms technique) fixation techniques. ...
There are several techniques to be found in literature for reducing odontoid fractures and atlanto-axial dislocations. In odontoid fractures, Uchiyami uses an assisted but active extension movement without anesthesia for reduction [14]. Advantages in this approach are direct feedback on neurologic symptoms and no risk of anaesthesia. Griffith describes reduction by constant traction which needs immobilization [11]. We here used the passive reduction under anesthesia in the operating room with fluoroscopy control as previously described by Mandabach [15]. As we opted for implantation of dorsal tension wires according to Brooks procedure, reduction under anesthesia with fluoroscopy control in the same session seemed most appropriate. Odontoid fractures in children can be treated with or without surgery depending on the stability of the fragment. For successful fracture healing, 50% contact of the fragments is reported to be sufficient in children [16]. Dislocation of the odontoid fragment into ...

DUNN, RN and STANDER, H. Atlanto-axial fusion: Magerl transarticular versus Harms instrumentation techniques. SA orthop. j. [online]. 2014, vol.13, n.2, pp.31-34. ISSN 2309-8309.. Transarticular screw fixation offers acceptably high fusion rates but is not possible in 18% of patients due to a high riding vertebral artery. It also requires pre-operative anatomical reduction which is not always possible. The Harms technique utilises a posterior C1 lateral mass and C2 pedicle screw. This allows easier access due to the angle of drilling and has become an increasingly popular surgical technique. AIM: The aim of this study is to review and compare the above techniques with regard to surgery, complications and outcome. METHODS: A retrospective case note and radiographic review of 42 patients undergoing posterior C1-2 fusion in a single institution during the period 2003 to 2011, identified on a prospectively maintained database, was performed. The indication for surgery was atlanto-axial instability ...
Although posterior segmental fixation technique is becoming increasingly popular, surgical treatment of craniovertebral junctional disorders is still challenging because of its complex anatomy and surrounding critical neurovascular structures. Basilar invagination is major pathology of craniovertebral junction that has been a subject of clinical interest because of its various clinical presentations and difficulty of treatment. Most authors recommend a posterior occipitocervical fixation following transoral decompression or posterior decompression and occipitocervical fixation. However, both surgical modalities inadvertently sacrifice C0-1 and C1-2 joint motion. We report two cases of basilar invagination reduced by the vertical distraction between C1-2 facet joint. We reduced the C1-2 joint in an anatomical position and fused the joint with iliac bone graft and C1-2 segmental fixation using the polyaxial screws and rods C-1 lateral mass and the C-2 pedicle. ...

Atlantoaxial instability implies excessive movement between the first cervical vertebra or atlas, and second cervical vertebra or axis.
There were four intra-operative unintentional durotomies with CSF leaks. Three were in the transar-ticular group. These were successfully dealt with at the time of surgery with surgical, muscle and/ or Duroseal.. There was one case of instrumentation failure with bilateral screw fracture in the transarticular group. Despite this the patient went onto successful fusion.. There were no cases of neurological deterioration or sepsis.. Median time to union was similar in both groups at around 5 months (Table IV). All Harms patients were fused by 9 months, with 18% of the transarticular group taking longer than this and one requiring revision for an established non-union.. Discussion. Atlanto-axial instability is a concern due to the risk of myelopathy and sudden death from proximal spinal cord compression.4 The decision to arthrodese the joint is based on the appreciation of this risk and the expectation that stabilisation will not occur spontaneously with conservative means.. In the case of trauma, ...
orthosis, 2 with a Minerva brace, and 1 with a halo. Two patients required cervical surgery; an occipital cervical fusion for a type 2 odontoid fracture and one atlantoaxial fusion for atlantoaxial instability was performed. At the follow up appointments, none of the patients were found to have delayed instability based on clinical examination, upright x-rays or flexion-extension x-rays. Conclusion: All isolated OCF are likely stable injuries. Our data suggests all isolated OCF may be treated conservatively with any type of cervical orthosis and minimal follow up. ...
The authors describe a novel posterior approach to atlantoaxial stabilization combining C1-2 transarticular and C1 lateral mass screws with vertical connecting rods to create a strong construct with four-point fixation. They present here a case of atlanto-axial instability secondary to infection, Grisels syndrome, necessitating instrumented stabilization after a period of close clinical and radiological observation following the initial cervical decompression and evacuation of retropharyngeal and epidural abscesses.
Twenty-three healthy adult participants (14 men and 9 women; mean [SD] age, 40 [12.6] years [range, 27-69 years]) were randomly assigned to an intervention group (n=11), in which HVT was applied to the atlantoaxial segment, or a control group (n=12), in which participants were held in the premanipulative hold position. Doppler ultrasonography was used to measure VA3 hemodynamics. Exclusion criteria included a history of known vertebral artery anomalies, hypoplasia, various spinal conditions, and more. Participants were also excluded if the investigators were unable to visualize VA3 on ultrasonography. The primary outcome measures were peak systolic and end diastolic velocities, which were measured at neutral, pre-HVT, post-HVT, and post-HVT-neutral positions. ...

If signs are mild, conservative therapy may be attempted. Your dog will be placed in a rigid neck splint and confined to a kennel for 6-8 weeks. Immobilization of the neck will, in theory, allow scar tissue to form that will help stabilize the joint. During this time, your dog will also be treated with pain medication to keep them comfortable and/or steroids to decrease spinal swelling. While some dogs will experience complete resolution of clinical signs with conservative treatment, many dogs will not, especially if their signs have been present for an extended period of time. The risks of conservative therapy can include progression of disease (including a risk of paralysis or death), as well as pressure sores from the splint/bandage rubbing against the skin.. In the case of long-standing neurologic signs, or a dog that has not responded to conservative treatment, surgery is often required. The goal of surgery is to permanently stabilize the atlantoaxial joint, in order to prohibit excessive ...
Objective To reveal the factors that determine the natural course of subluxation of occipital-cervical lesions in rheumatoid arthritis (RA). The atlanto-axial region is one of the most common locations for lesions in RA. Some cases progress from reducible atlanto-axial subluxation (AAS) to irreducible vertical migration, while others continue to exhibit reducible AAS. No study has revealed the factors that determine the natural course of subluxation. We focus on the odontoid as a key structure of the progression of occipito-cervical lesions and investigated this region in patients with RA using reconstructive computed tomography (CT) images, and analyzed factors in association with CT findings. ...
If the spinal vertebrae are misaligned in such a way as to bring pressure and irritation to the nerves which travel through their openings . . . a condition exists, which is referred to as subluxation.. Since these nerves serve all parts of the body, providing a vital pathway to and from the brain, any subluxation that hinders or disrupts their function endangers the well-being of the entire body. These subluxations may be of an acute nature, causing sudden painful symptoms or the chronic type, which may result in long-term, painful degeneration and resulting impairment. Actually though, subluxations dont cause symptoms - they cause decreased function of the nervous system, which by itself will ultimately lead to symptoms.. Subluxations are often deceiving since the symptoms may appear at a point in the body far from the cause. Simple treatment of the symptom alone is generally fruitless. The longer the cause of the problem is allowed to exist, the longer and more difficult it is to correct. ...

Vertebral subluxations have a great number of different causes all of which the average individual is exposed to daily. These causes can be described in terms of physical, chemical, and emotional causes. Physical causes include acute trauma to the body, repetitive motions affecting the spine, bad postural habits, improper workstation habits and design, and weak or imbalanced spinal musculature. Chemical causes include poor dietary and nutritional practices, drug and alcohol use and abuse, and the ingestion of chemical toxins in the foods we eat, air we breath, and water we drink. Chemicals which are harmful to the body decrease the bodys ability to function optimally and reduce the ability to successfully adapt to and withstand internal and external stresses - making us more susceptible to spinal subluxations and the consequences of these subluxations. Emotional causes refer to stress. Excessive stress or inadequate stress management skills can deplete the body of the ability to sustain normal ...

BACKGROUND AND OBJECTIVES: Accidental breach of the vertebral artery (VA) during the performance of cervical pain blocks can result in significant morbidity. Whereas anatomical variations have been described for the foraminal (V2) segment of the VA, those involving its V3 portion (between the C2 transverse process and dura) have not been investigated and may be of importance for procedures targeting the third occipital nerve or the lateral atlantoaxial joint.

Causes of subluxations fall into three broad categories: physical, chemical, and emotional.. Any bodily trauma like car accidents, falls, sports injuries, heavy lifting, surgery, or genetic weaknesses can cause physical subluxations. A repeated posture like leaning uncomfortably forward at a desk can factor into subluxation patterns. A difficult birthing process, for mother and child, is also a common cause.. When looking at root causes for chemical subluxations, we look to environmental factors and substances taken into the body, either through the lungs, skin, or digestive system. Habitual smoking, illegal and legal drug use, excessive use of alcohol, chronic dehydration, and poor nutrition, are some of the factors too.. Emotional subluxations originate from stress on the mind and body. This can range from something small, like the stresses from the daily grind to major emotional stressors, such losing a job or loved one.

You have more than 200 bones in your body. Whenever two bones come together at a joint, there can be movement. Since joints in your spine are so close to your spinal cord and nerve roots, too much or too little joint motion can have serious effects.. If spinal bones get stuck and don t move right, they can irritate or chafe delicate nerves. If a joint moves too much, spinal bones can press against adjacent nerve tissue. This can interfere with the vital life force transmitted over your nervous system that helps keep your brain in touch with your body.. The result is the vertebral subluxation complex, or more simply, a subluxation.. Distorted Communications Between Your Brain and Your Body Can Cause All Kinds of Health Problems. More than bones and nerves are involved. Muscles can become too tight or too weak. Discs, ligaments and other connective tissues can become inflamed. Bone spurs and arthritic degeneration can set in.. Subluxations are serious!. However, the most important aspect of a ...

Complications of uncorrected subluxations may be serious, resulting in respiratory depression, and in some cases SIDS. Infants who survive and are properly diagnosed for subluxations have a better chance of having the neurological defects ultimately eliminated.6 A wide range of subluxations may occur, primarily due to the stretch injury and/or compression of the spinal cord and brain stem. As the vertebrae are forced out of their natural alignment, spinal and cranial nerve roots, as well as the dura and surrounding structures, may be torn.. Most authorities believe that brain stem and spinal injuries at birth are essentially attributable to excessive longitudinal traction, especially when force is combined with flexion and torsion of the spinal axis during delivery.. Although birth subluxations may cause immediate symptoms, there may be far-reaching effects that are manifested for years. The childs ability to fight against disease, for example may be lowered. Cold, ear infections, colic, and ...

Eat them in moderation, and choose other foods to provide the balance and variety that are vital to good health.. Your Nervous System & Digestion - Your brain communicates with every cell in your body through the miles of nerve fibers that make up your nervous system. When this communication is interrupted, problems can occur. All of your bodys functions are regulated by your nervous system. It causes the heart to beat, lungs to breathe, muscles to contract, stomach to digest, and glands to secrete.. Your Spinal Column - The brain is protected by the skull. The spinal cord, which connects the brain to the body, has a unique protection. It is protected by a combination of twenty-four bony segments, called vertebra, and soft tissue. The soft tissues give the spine the ability to bend while maintaining its protective alignment.. Vertebral Subluxations - Spinal distortions interfere with nerve function and are called subluxations. When the spine becomes distorted or misaligned, the contents of the ...

Taking x-rays is a great way to get a look inside your body and see what is really happening in the spine and joints. It can not only help us detect subluxations, but it can also give us clues to other things that may be happening within your body that you dont know about. Sometimes we will find what is called a congenital anomaly, which is often a minor abnormality that has no medical or cosmetic impact on a person. Other times, x-rays will reveal old fractures or injuries that you didnt even know happened. In rare cases, x-rays can show us that there is a pathology present, such as bone disease or cancer. In this instance, you will be given a referral to a specialist that can assist you with your condition. ...

This is the first case report of a traumatic odontoid process synchondrosis fracture in a calf. Neurological examination was useful for early and correct neuroanatomical localisation. Radiography was easy to perform and allowed an initial diagnosis. MRI and CT examination (although performed post-mortem for scientific interest) were helpful for sub-classifying the fracture type, excluding additional (traumatic or congenital) cervical lesions and, potentially, allowing better planning of potential surgical interventions. However, as evident in our case, transportation to the advanced diagnostic imaging site incurred the risk of further displacement and neurological deterioration, suggesting that the benefits versus risks of any procedure and transport should be carefully considered.. So far, detailed classification systems of atlantoaxial fractures are lacking in veterinary medicine. In humans, several classification systems for odontoid process fractures have been established but are still a ...
Between 1989 and 1994, 50 patients suffering from congenital atlantoaxial dislocation with either an assimilated atlas or a thin or deficient posterior arch of the atlas were treated with occipitocervical fusion using the technique described by Jain and colleagues in 1993 with a few modifications. An artificial bridge created from the occipital bone along the margin of the foramen magnum was fused to the axis using sublaminar wiring and interposed strut and lateral onlay bone grafts. Ten patients (20%) also underwent atlantoaxial lateral joint fusion by intraarticular instillation of bone chips. In 22 patients (44%) with irreducible dislocation, posterior fusion was preceded by transoral odontoidectomy. In seven patients (14%) with ventral compression, who showed marked clinical improvement on traction despite radiological evidence of persisting atlantoaxial dislocation, occipitocervical fusion was performed without ventral decompression. Seven patients (14%) underwent a single-stage transoral ...
Objective: Nowadays anterior resection of the odontoid process is rarely indicated.. Removal of the odontoid is for instance conducted for decompression in patients with rheumatoid arthritis and basilar invagination. The transoral approach to the odontoid process is well established for many years despite its associated complications. An endoscopic transnasal approach to the odontoid process was introduced recently. Experience with the endonasal novel approach is limited and range of indication for this approach is still inexplicit.. Methods: With a case of a 77-year-old woman with retrodental tumor and cervical myelopathy who underwent dorsal fusion a week prior to odontoid resection and a case of a 64-year-old woman with rheumatoid arthritis and severe symptomatic basilar impression who already underwent dorsal atlantoaxial fusion more than 20 years ago the technique of endoscopic transnasal odontoid resection is demonstrated. A pure endoscopic transnasal approach was used; neuronavigation on ...

Vertebral subluxations have a great number of different causes all of which the average individual is exposed to daily. These causes can be described in terms of physical, chemical, and emotional causes. Physical causes include acute trauma to the body, repetitive motions affecting the spine, bad postural habits, improper workstation habits and design, and weak or imbalanced spinal musculature. Chemical causes include poor dietary and nutritional practices, drug and alcohol use and abuse, and the ingestion of chemical toxins in the foods we eat, air we breath, and water we drink. Chemicals which are harmful to the body decrease the bodys ability to function optimally and reduce the ability to successfully adapt to and withstand internal and external stresses - making us more susceptible to spinal subluxations and the consequences of these subluxations. Emotional causes refer to stress. Excessive stress or inadequate stress management skills can deplete the body of the ability to sustain normal ...

A wonderful and much-needed review of studies to date and some common-sense recommendations. Theres a lot here, so I want to hit on the more important points by the author. First, the background. The craniovertebral joint is made up of the skull and the first two cervical (neck) vertebrae. The first cervical vertebra, C1, is called the atlas and has the shape of a ring. It sits on top of the second vertebra, C2, which is also called the axis. The axis has a protrusion called the odontoid process. In Down syndrome, a combination of bony abnormalities and lax ligaments contribute to the instability called atlantoaxial instability (AAI). For more background on the controversy on the diagnosis and treatment of this condition, see my essay on AAI. On the topic of radiologic screening, Dr. Brockmeyer reviews the studies to date and contends that on lateral (side view) neck X-rays, the measurement called the neural canal width is much better than the commonly used atlanto-dens interval, as it ...
The CT examination (Fig. 2a-e) shows erosion of the odontoid peg (arrowed on Fig. 2a) and atlanto-axial subluxation with antero-lateral translation of C1 of C2. Superior migration (cranial settling) of the odontoid peg is seen (Fig. 2b) with the odontoid tip at 6mm above the McGregor line (drawn from hard palate to occiput: normal ,4.5mm). CT images are also able to better demonstrate facet joint arthropathy dominating at the upper to mid cervical levels and multilevel uncovertebral degenerative changes. A left C2/3 facet joint fusion is also shown (Fig. 2d-e ...

Indications for surgical treatment include neck pain, neurologic dysfunction, or abnormal imaging parameters (instability). Often patients present with a combination of these factors:. 1. Pain: Neck pain or occipital pain has multiple etiologies. If pain is secondary to spinal instability or neurologic compression (e.g. radiculopathy, myelopathy), surgery is recommended. 2. Neurologic dysfunction: Cervical myelopathy is an indication for surgery to prevent neurologic deterioration and facilitate recovery. 3. Abnormal imaging parameters:. A. ATLANTOAXIAL SUBLUXATION (AAS). • AADI greater than 10 mm. • Spinal cord diameter less than 6 mm in neutral or flexed position (MRI). • Spinal canal diameter less than 10 mm in flexed position (MRI). • Inflammatory tissue behind the dens greater than 10 mm. B. ATLANTOAXIAL IMPACTION (AAI). • Cervicomedullary angle less than 135 degrees on sagittal MRI. • Cranial migration distance less than 31 mm (Redlund-Johnell measurement). • Migration of ...
Subluxation Syndromes. A subluxation syndrome has been defined as an aggregate of signs and symptoms that relate to pathophysiology or dysfunction of spinal and pelvic motion segments or to peripheral joints.3 While the signs and symptoms characteristic of subluxation syndromes are not always due to a subluxation, when they are, the condition commonly is responsive to adjustive and manipulative procedures. It is important the examination of patients be inclusive of the clinical indicators that identify subluxations. The components of the PARTS exam, developed by Bergmann4 and included in the Medicare Benefit Policy Manual that covers medical and other health services,5 commonly is used to identify subluxations. Subluxation of the Upper Cervical Vertebrae Headaches from subluxations in the upper cervical vertebrae are responsive to adjustive and manipulative procedures.6 Cervicogenic headache is the term most frequently used to describe the syndrome characterized by neck and suboccipital pain ...

Individuals with mechanical neck pain often have pain and a loss of mobility in the upper cervical spine, specifically at the atlanto-axial (C1-C2) joint. This joint is primarily responsible for cervical rotation, but also contributes to small amounts of flexion and extension. Arthrokinematically, during left rotation, the left facet of the atlas(C1) glides posterior on the axis (C2) & the right facet of the atlas glides anterior. During flexion, the facet of the atlas glides anterior and rolls posterior in relation to the axis. The opposite happens with extension ...
OBJECTIVE Spondylolisthesis is a prevalent spine disease that recent studies estimate could be detected in 9% of the population. High-grade spondylolisthesis (HGS), however, is much less frequent, which makes it difficult to develop a general recommendation for its treatment. Posterior transdiscal fixation was proposed in 1994 for HGS, and the use of spine navigation could make this technique more accessible and reduce the morbidity associated with the procedure. The purpose of this study was to present a case series involving adult patients with HGS and correct spinal alignment who were treated with transdiscal pedicle screw placement guided with neuronavigation and compare the results to those achieved previously without image guidance ...
