Uncovertebral joint (enlarged), anterior view of coronal section.
Uncovertebral joints form during childhood between the uncinate processes of C3-C6 and the vertebral bodies immediately superior. The joints may result from fissures in the cartilage of the disks that assume an articular character. If the fissures become complete tears, the risk of pulposus herniation is increased.
