Fig. 2From: Cam morphology and inguinal pathologies: is there a possible connection?Centre-edge angle (CEA) measurement on an AP pelvis X-ray. The CEA is the angle between the line connecting the centre of the femoral head and the acetabulum and the line perpendicular to the line connecting the sit bones of the ischial tuberosity. A value of ≥40° is consistent with a pincer morphologyBack to article page
