Femoroacetabular Impingement QID: 8591 (SAE13SM.34)

QID 8591 (Type "8591" in App Search)

Figures 34a and 34b are the radiographs of a 38-year-old woman who had increasing left hip pain with activity. She noted no lower back or buttock pain and no pain along her lateral thigh. The pain usually only bothers her with running and cycling. Nonsteroidal anti-inflammatory drugs helped initially but are not relieving her pain now. Examination with the patient supine reveals pain with internal and external rotation of her hip with her hip and knee in an extended position. With her hip flexed to 90 degrees, she has internal rotation only to neutral, but full external rotation. What is the most likely diagnosis?

This patient has pincer femoroacetabular impingement. Her examination demonstrates pain with internal and external rotation of the femoral head in the acetabulum, suggesting intra-articular pathology. She also has a noticeable loss of internal rotation. Her examination findings make the other possible diagnoses unlikely. Her radiographs show a crossover sign, which suggests overcoverage by the anterior acetabulum, often the result of acetabular retroversion.
