Forward displacement of a vertebra is described by which term?

• A. Backward displacement of a vertebra
• B. Forward displacement of a vertebra
• C. Inflammation of vertebrae
• D. Degeneration of intervertebral discs

Answer: (B)

In spine terminology, forward displacement of a vertebra is described as anterolisthesis, the anterior slip of one vertebra relative to the one below. The term that matches this directional concept is the one that literally describes forward displacement, making it the best pick. In common usage, spondylolisthesis is the general term for forward slippage, while anterolisthesis specifies the forward direction. The other options describe backward displacement (retrolisthesis), inflammation of vertebrae (spondylitis), and degeneration of intervertebral discs (spondylosis), which are different conditions.
