Spondylolysis and Spondylolisthesis

Spondylolysis and Spondylolistheses are the most common causes of lower back pain in adolescents. Spondylolysis is a fracture in one or both pedicles of the vertebrae that make up the spinal column. It usually affects either the fourth or the fifth lumbar vertebra in the lower back. The fracture site is called  pars defect.If the bone is unable to maintain its proper position, the top vertebrae can shift forward on top of the bottom vertebrae. This condition is called spondylolisthesis.

For adults, spondylolisthesis is normally caused by degenerative changes. When too much movement or slippage occurs, the bones may begin to press on nerves and surgery may become necessary to correct the condition. Causes such as genetic, overuse or degenerative changes can contribute to development of spondylolisthesis.
