Surgical treatment of the hip in cerebral palsy.

Hips are affected generally in CP but in favourable cases we can prevent dislocation by adductor tenotomy performed in time (530 cases). Posterior transposition of the origins of the adductor muscles is performed if the patient walks with inwood rotated inferior extremities (105 cases). In the treatment of real subluxation and valgus deformity the open tenotomy of adductor muscles and femur osteotomy with derotation and varisation were used (180 cases). We accomplish open reduction in frank dislocation (35 cases). In such cases it is often necessary to shorten the femur. Also normal acetabulum is found in elder children.
