The Joint Preservation, Resurfacing and Replacement department offers comprehensive diagnostic services for hip impingement. Diagnosis begins with a complete medical history and a physical examination.
During the physical exam, the range of motion of the hip joint and presence of impingement will be assessed. Other tests may be required, including:.

By realigning the joint properly, the abnormal contact can be reduced or eliminated. An abnormally shaped femoral head or hip socket can often be reshaped with osteoplasty or debridement. A lateral radiograph of the hip in a year-old male with hip pain is shown 1. The prominence of the femoral head-neck junction is demarcated with arrow A.

This is consistent with cam impingement. This patient also has a fracture of the acetabular rim as demarcated by arrow B. At surgery 2 the femoral head demonstrates the damaged articular cartilage arrow and prominence of the femoral head. The surgical correction of this deformity 3 and the post-operative x-ray 4 are shown.
