Spondylolisthesis: Definition, Uses, and Clinical Overview
Spondylolisthesis is a spine condition where one vertebra slips relative to the vertebra below it. It is most commonly discussed in the lower back (lumbar spine), especially at L4–L5 or L5–S1. Clinicians use the term to describe a structural alignment problem that can be seen on imaging. It is often used in conversations about back pain, leg pain, and spinal stability.
