Cervical Zygapophyseal (Facet) Joint | |
---|---|
Primary Type | Synovial Joint |
Secondary Type | Planar Joint |

Ligaments | |
Muscles | |
Innervation | |
Vasculature | |
ROM | |
Volume | |
Conditions |
C0-1 | C1-2 | C2-7 | |
---|---|---|---|
Anatomy | 1. Superior facets of C0 (Atlas): 28° in sagittal and transverse planes
2. No disc |
1. C1 has convex facet joint surface (allow C1 facet to slide in AP direction over C2)
2. No disc 3. Transverse lig : prevent dense posterior dislocation 4. Alar lig: limiting rotation |
Anatomy structure grossly similar.
1. 2x uncovertebral joints (joints of Luschka) at each segments. They are not true synovial joints (clefts at the lateral edges of IVD between uncinated process inferiorly, and the edge of the vertebral body above) 2. 1 disc between each vertebra body. 3. 2 facet joints: at 45° inclination to horizontal plan (pure rotation, side bending is limited) |
Biomechanics |
|
Rotation: 45° both directions.
(Rotation in full flexion is C1-2 rotation) |
