Osteotomies

There are several types of osteotomies described in the literature (e.g., rotational, angulation). No matter what type they all have the same goal, to preserve the femoral head by altering the pattern of stress transfer. A varus osteotomy attempts to shift the most involved portion of the head medially. A valgus osteotomy attempts to shift the superolateral lesion more lateral. Often varus and valgus osteotomies are performed in conjunction with a flexion osteotomy. Rotational osteotomies by design attempt to shift the diseased head medially, inferiorly and posteriorly.
