What is retrolisthesis?

Retrolisthesis refers to the backward displacement of one vertebra relative to the one below it. This condition typically results from degeneration, trauma, or other pathological processes affecting the spine. The displaced vertebra can lead to a narrowing of the spinal canal or intervertebral foramen, which may cause nerve compression and result in pain or neurological symptoms.

Understanding this terminology is essential for orthopedic technologists, as it aids in diagnosing spinal conditions and determining appropriate treatment and management strategies. Recognizing the difference between vertebral displacements, such as retrolisthesis and anterolisthesis (forward displacement), is crucial in the context of spinal health and injury. The other answer choices describe different conditions or issues related to the spine but do not accurately define retrolisthesis as understood in orthopedic terminology.
