Spondylolisthesis is a condition in which a vertebra in the spine slips out of its normal position, often causing back pain and nerve compression. It can result from aging, trauma, or genetic factors. This displacement can lead to symptoms such as lower back pain, muscle tightness, and numbness or weakness in the legs. Treatment options include physical therapy, pain management, spinal bracing, and in severe cases, surgery to stabilize the spine. Proper body mechanics and strengthening exercises can help manage spondylolisthesis and prevent further slippage.
