Varus derotational osteotomy of the femur in cerebral palsy

Varus derotational osteotomy of the femur is designed to correct coxa valga and femoral anteversion which contribute to progressive hip subluxation and dislocation in certain cases of cerebral palsy. By the application of a careful preoperative evaluation, vigorous postoperative rehabilitation and treatment of complications, satisfactory results were obtained in 17 of 20 patients followed for one to 17 years after osteotomy. No hip subsequently dislocated and dysplastic acetabulae were predictably remodeled in those patients less than 8 years of age.
