Abstract:
Abnormalities of the femur frequently accompany acetabular dysplasia as primary or secondary deformities. Femoral surgery is often a component of surgical treatment of acetabular dysplasia either at the onset or to treat a secondary or residual deformity. Proper analysis of the abnormal geometry of the bony femur, as well as the abnormal lever arms around the hip related to the lesser and greater trochanteric positions, is an essential part of a successful surgical plan. An à la carte approach makes the most sense in the treatment of the wide variety of disorders of the upper femur. Over 100 years of hip surgery has proven that normalizing the anatomy and muscle forces around the hip to as close to normal as possible, extends the future life of the hip while also treating current pain and disability.
