Intertrochanteric osteotomy for osteonecrosis.
Intertrochanteric osteotomy is an effective surgical option in certain well-selected cases of osteonecrosis of the femoral head.  The size of the lesion on plain radiographs in the anteroposterior and lateral projections is a critical determinant of success.  The best candidates are patients with less than 50% of head involved in the necrotic sector.  Collapse of the femoral head is not a contraindication to osteotomy.  Location of the necrotic sector determines whether varus, valgus, flexion, or extension are most appropriate alone or in combination.
