Spondylolisthesis

Spondylolisthesis is a spinal condition where one vertebra slips forward over the one beneath it, often in the lumbar spine. This slippage can result from congenital defects, degenerative changes, trauma, or stress fractures, especially in athletes. Symptoms may include lower back pain, stiffness, muscle tightness, and nerve compression leading to leg pain, numbness, or weakness.
