A wide spectrum of morphologic abnormalities of both the acetabulum and the proximal part of the femur can lead to hip pain in the young adult1-3. These developmental, or occasionally acquired, abnormalities may present clinically with symptoms and signs of both hip instability and femoroacetabular impingement1,4,5. Also, it is now recognized that a classically dysplastic or unstable hip may begin to manifest impingement as a result of an iatrogenic cause. For example, periacetabular osteotomy6 performed to improve coverage of the femoral head can lead to relative acetabular overcoverage and resultant femoroacetabular impingement2,7. Alternatively, a hip that is being treated for impingement can become unstable as a result of the performance of an acetabular rim resection and a femoral head osteochondroplasty8,9. Finally, hips that have a combination of impingement and instability may require acetabular reorientation to treat the underlying intra-articular pathology10.
In our experience, many patients . . . [Full Text of this Article]
