CERVICAL SPONDYLOLISTHESIS

Thursday, 28th Jun 2018

spondylolisthesis is the term used for the slipping of a vertebtal body from the one below it.
The direction of slip is usually forwardc but can sometimes be backwards also. Cervical spondylolisthesis is usually less common as compared
to lumbar spondylolisthesis.
The stability of cervical spine depends on the pedicle, par-interarticularis and the inferior articular facet locking over the superior facet of the
vertebra below. Usually, the vertebra slips forwards when the pars- interarticularis gives way or separates.
CAUSES:
1. Congenital non fusion of the dens ( odontoid process) with the body of axis.
2. Inflammatory lesion of upper part of neck which causes softening of the transverse ligaments of atlas.
3. Any previous trauma
4. Conditions like rheumatoid arthritis.
5. Pathological bone weaking ( either due to any malignancy or osteoporosis).
6. Spondylosis causing separation of pars-interarticularis.
7. Degenerative which may lead to subluxation of facet joints.

CLINICAL FEATURES:

1. Painful flexion deformity of neck.
2. Neck stiffnes
3.Nerve root compression symptoms depending on the level of subluxation.
4. Spinal cord compression may also occur causing radiating pain to the extremities.
