Deformities of the hip in cerebral palsy are caused by imbalance of muscle power. The flexion-internal rotation combined adduction deformity is common and causes the crouched position, scissors gait and furthermore hip subluxation.
To correct this deformity we tried modified Barr's operation combined with muscle release or osteotomy of the femoral neck.
We have found this procedure has the effect of reenforcing the power of abduction and it is beneficial to treat the hip disorder in cerebral palsy.
