Which line of mensuration is used to find a spondylolisthesis?

George's line on a lateral spine radiograph is used to detect spondylolisthesis. Drawn along the posterior margins of the vertebral bodies, it should form a smooth, continuous line. When a vertebra slips forward, the posterior edge no longer aligns with the line above or below, creating a visible step or break. This makes George's line the most reliable reference for identifying and assessing spondylolisthesis and helps gauge how much slip has occurred, often in conjunction with grading the displacement. For context, Cobb's line or angle is used to measure scoliosis, not listhesis; Shenton's line is a check for hip joint integrity on pelvic radiographs; Ferguson line is not the standard measure for spondylolisthesis.
