OBJECTIVE. The purpose of this article is to show the important radiographic criteria that indicate the two types of femoroacetabular impingement: pincer and cam impingement. In addition, potential pitfalls in pelvic imaging concerning femoroacetabular impingement are shown. CONCLUSION. Femoroacetabular impingement is a major cause for early 'primary' osteoarthritis of the hip. It can easily be recognized on conventional radiographs of the pelvis and the proximal femur.
