Spondylolisthesis

Spondylolisthesis – Condition caused by a deformity or weakening in part of the spine, in which one bone, or vertabra, slips forward over another resulting in a misalignment. This may lead to spinal cord or nerve root compression, meaning that pressure is placed on the nerves and bones in the spine. Symptoms may include back pain, and numbness or weakness in the legs.
