Spondylolisthesis. Diagram shows how to grade spondylolisthesis. The 2 arrows, one indicating vertebral body width and the other indicating the amount of slippage that has occurred, represent the measurements needed.
The ratio of amount of slippage to vertebral-body width is obtained as a percentage. Grade 1 is a ratio of 0-25%, grade 2 is 25-50%, grade 3 is 50-75%, and grade 4 is 75-100%.
