Twenty @entity1 (twenty hips) with @entity306 underwent femoral varus-derotation osteotomy for which the principal indication was inadequate coverage of the femoral head. Other infrequent indications included @entity158 , valgus angulation of the femoral neck, and @entity572 . The age at surgery ranged from four to fifteen years. Each @entity1 had muscle releases before the osteotomy was done. At follow-up, at least seven years later, the femoral head in twenty hips was well centered. Four hips remained subluxated but were less subluxated than before the osteotomy. One hip remained dislocated. The center-edge angle averaged -8 degrees preoperatively and +17 degrees at follow-up. The neck-shaft angle averaged 155 degrees preoperatively, 114 degrees immediately post-operatively, and 125 degrees at follow-up. @entity2096 , when combined with muscle releases, can allow @entity1 with @entity306 to maintain their ambulatory status and may decrease @entity158 about the hip.
