Role of innominate osteotomy in the treatment of children with Legg-Perthes disease.

Innominate osteotomy is based on the supposition that coverage of the femoral capital epiphysis is necessary. The morbidity is minimal, early postoperative weight-bearing is permissible, even encouraged. No further evidence of deterioration of the contour of the hip joint appears following surgery. Prompt consolidation of the fragments may occur. In selected cases innominate osteotomy can provide a better prognosis than non-operative treatment.
