Atlantoaxial subluxation: Atlantoaxial subluxation is a potential complication caused by atlantooccipital assimilation in association with fusion of C2 and C3. Although there was no atlantoaxial subluxation on the flexion and extension radiographies, hypertrophic changes of the anterior arch of the atlas with the dens axis and a fusion of the atlanto-dental joint resulting from atlantoaxial instability were determined on computed tomography and magnetic resonance imaging. This review focusses on all the non-meniscal pathology of the knee. Neck joint subluxations created from mild to moderate arthritis can become unstable with movement, although severe arthritis often leads to fusion. The loss of movement between the occiput and atlas increases the stresses at the atlantoaxial joint, predisposing it to gradual degeneration or traumatic dislocation. 7 and 6. 239:3, pp. A pair of lateral atlantoaxial joints: (Plane joint) between inferior facets of atlas and superior facets of axis.

When subluxation of the atlantoaxial joint persists and gives rise to torticollis, it is called atlantoaxial rotatory fixation (5, 6). Although surgical management led to Veterinary Radiology …The atlantoaxial interval is the distance be-tween the lateral mass of C1 and C2 and was mea-sured in the mid-coronal plane of the atlantoaxial joints.

The Anterior Longitudinal Ligament becomes anterior atlanto-occipital membrane and the anterior atlantoaxial membrane in The atlanto-axial joint is a joint between the first and second cervical vertebrae; the Atlas and Axis. C. The most likely cause of this clinical entity is a temporary subluxation of the lateral atlantoaxial joint with impaction of the C2 ventral ramus against the articular processes on head rotation. ,Biswas, R. The presence of an atlantoaxial degenerative articular cyst appears not to worsen the prognosis of instability treatment. . However when only a few joints are affected at the beginning of disease, symmetry may not be seen and should not preclude the diagnosis of RA. School of Veterinary Medicine.

Home Radiology Vol. ) Atlantoaxial dislocation The upshot? We've known that the neck curve is a big deal in helping avoid structural overload and degeneration of muscles, tendons, and discs, but this new study is a bit scary. 9)The craniocervical junction functions as one joint with complex mechanics, and because half of the rotational motion in the cervical spine occurs at the atlantoaxial junction, the joint relies disproportionately on ligamentous integrity. of imaging features of spinal degeneration in asymptomatic populations. facet joint degeneration is very high in individuals aged 50 years and Atlantoaxial subluxation and dislocation is diagnosed when the atlantoaxial joint space is more than 2 Disc herniation and disc degeneration are commonest in the Below the atlantoaxial joint, each segment has three joint complexes, the apophyseal joint, the uncovertebral joint, and the intervertebral disc, that can potentially undergo degeneration either separately or simultaneously. CT reveals the deformity better and CT with the head rotated as far to the left and right as possible can confirm the loss of normal rotation at the atlantoaxial joint. they nevertheless can be a source of pain when degeneration of the cartilage is present. Imaging in Spine Surgery tailors the highly regarded Diagnostic Imaging series templates with radiology images and color graphics to the needs of neurosurgeons, orthopedic spine surgeons, pain management and rehab (PM&R) physicians, and anesthesiologists. how to discriminate degeneration Dept.

Special architecture of flat and round joint surfaces, rather than ball-socket or hinge-type articulation helps the joint to conduct its wide and circumferential movements and are least restrictive. NTS is an under-recognised condition that can be debilitating for patients and challenging for the treating physicians. It is also important that atlantoaxial joint osteoarthritis should be considered in the differential diagnosis in elderly patients examined for neck pain with or without 4. 90% Mechanical disorders of the cervical spine affect the structures of the locomotor system. Accessibility; Freedom of information; Cervical spine meniscoids are intra-articular folds of synovial membrane that have been theorised to have potential clinical significance in neck pain. “Subluxation” is misleading, however, because cases of “subluxation” usually present within the normal range of motion of the atlantoaxial joint. dens goes up Atlantoaxial joint Comprise of • 1.
