What condition is described when one vertebra slides forward below another?

Spondylolisthesis is a condition characterized by the displacement of a vertebra, specifically when one vertebra slides forward over another adjacent vertebra. This slippage can lead to various issues, including nerve compression, back pain, and other symptoms associated with spinal instability. The forward movement alters the alignment of the spine, which can disrupt its normal function and lead to complications if not addressed.

Understanding this condition is crucial, especially in fields related to physical therapy and sports medicine, where spinal integrity is vital for proper movement and preventing injuries. Recognizing spondylolisthesis can aid in diagnosis and inform treatment plans that may involve physical therapy, pain management, or, in some cases, surgical intervention.
