Spondylolisthesis
Your lower back is called your lumbar spine. It is made up of five bones called lumbar vertebrae. The vertebrae have two major parts, a solid part called the body and a bony ring through which the lower part of the spinal cord and nerves travel. Between the bodies of the vertebrae is shock absorbing material called disks. Part of the ring of each vertebra, called the pars, touches the vertebra above it and the vertebra below it.
Spondylolysis is a condition where there is a break in one or both sides of the ring of a vertebra. Spondylolisthesis is a condition in which a break in both sides of the ring allows the body of the vertebra to slip forward. Spondylolysis and spondylolisthesis most commonly occur at the fourth or fifth lumbar vertebrae. These conditions are also called pars defects, pars stress fractures, or stress fractures.
