The atlanto-occipital articulation (also known as the C0-C1 joint / articulation) is comprised of a pair of condyloid synovial joints that connect the occipital bone (C0) to the first cervical vertebra (atlas/C1). The atlanto-occipital (AO) and atlanto-axial (AA) joints are unique joints in the spine, connecting the cervical region to the base of the skull. These strong neck muscles, together with a network of corresponding ligamentous attachments, provide stability to the atlanto-occipital joint (AOJ). In 1987, Kaufman et al 7 measured the atlanto-occipital joint space in 100 normal children, at 5 evenly spaced points on the cross-table lateral radiograph of the skull.

Answer:It is appropriate to report code 64490, Injection (s), diagnostic or therapeutic agent, paravertebral facet (zygapophyseal) joint (or nerves innervating that joint) with image guidance (fluoroscopy or CT), cervical or thoracic; single level, for either atlanto-occipital or atlanto-axial joint injection. Lateral and median joints [ edit] Together they come together to form a joint that has as unique shape. Occipitocervical fusion (screw fixation) Select a chapter. There are no data found in the literature for adults. That is why your head falls forward when you fall asleep in the class. The atlanto-axial joint is a joint between the atlas bone and the axis bone, which are the first and second cervical vertebrae.

The movements allowed in the craniocervical region are shown in Table 7-9. The atlantoaxial joint is the most mobile portion of the spine, predominantly relying on the ligamentous framework for stability at that level. Widening of the joint can be used to detect instability at the C1-C2 level. There are two types of atlanto-occipital injuries: atlanto-occipital dislocation (Figure 1) and OC fractures. Each joint consists of two reciprocally curved articular surfaces. Atlanto Axial Joint Hypertrophy will sometimes glitch and take you a long time to try different solutions. It yields about 30 degrees of total flexion-extension in the sagittal plane, but only about 15 degrees of lateral flexion and 5 degrees of rotation. The journal publishes majorly in the area(s): Magnetic resonance imaging & Sarcoma. magnetic resonance images of the left atlantooccipital joint: t2w transverse (a) and sagittal (b) images show the presence of moderate synovial effusion (arrows), while t1 fat-saturation axial sequence (c) after intravenous contrast administration shows the presence of the dilated vein associated with synovitis, without erosions of joint facets Hence the Atlanto-occipital joint (AO) is the union of the C1 and C0 bones. Traumatic instability is treated with occipitocervical fusion. The atlanto-occipital and atlanto-axial joints are common causes of neck pain and stiffness due to occurrences like acceleration/deceleration injuries (e.g. Type & Articular surfaceThese are synovial joints of the ellipsoid variety.Above: The occipital condyles, which are convexBelow: The superior articular facet.
