Abstract: Objective To assess the image findings of femoroacetabular impingement (FAI).Methods Image findings of 9 patients with surgically proved femoroacetabular impingement were retrospectively reviewed for characteristic image findings of FAL All 9 patients underwent X-ray examinations and MRI of affected hip, and 1 patient underwent MR arthrography (MRA) additionally. Results X-ray examinations of all 9 patients showed bump at femoral head-neck junction or overcoverage of the acetabula.MRI showed various degrees of injury of anterosuperior labrum in all 9 patients. The injuries were stage Ⅰ A in2 cases, stage Ⅰ B in3, stage ⅡA in2, and stage ⅡB in 2. MRA of the case showed tears of anterosuperior labrum, with contrast media entering into the teared labrum. There were sclerosis and cystic degeneration of subchondral bone of femoral head in 2 cases, and these findings were confirmed as cartilage delamination by surgery. Conclusions MRI can display the injures of labrum and articular cartilage, which is helpful to the early diagnosis of FAI.
