Quizplus · Accepted Answer

Disruption of the posterior body (George's) line is a radiographic finding associated with spondylolisthesis. This line is normally a smooth line formed by the posterior margin of the vertebral bodies on lateral lumbar radiographs. Disruption of the line is indicative of a shift or displacement of the vertebral body, which is characteristic of spondylolisthesis. The other radiographic findings mentioned (inverted Napoleon hat sign, bowline of Brailsford, collared "Scottie dog") are not specific to spondylolisthesis.
