Spondylosis(redirected from rhizomelic spondylosis)
Also found in: Dictionary, Medical.
a chronic degenerative disease of man affecting the intervertebral joints. With spondylosis, primary changes develop in an intervertebral disk, causing the disk to lose elasticity and flexibility and to become less capable of absorbing shocks. The resulting deformity of the vertebral bodies (with spinous processes on their edges) produces pain, usually because the root of a spinal nerve is compressed by part of an intervertebral disk and the mobility of the affected segment of the spine is limited. The causes of spondylosis are the same as those of spondylarthrosis, and diagnostic and treatment methods are identical.
