Adduction contracture of the hip is the most common hip deformity in the spastic type of cerebral palsy. A high incidence of severe coxa valga, subluxation, and dislocation of the hip is associated with this contracture. In severe scissoring with adduction contractures of the hips, an adductor myotomy combined with anterior obturator neurectomy uniformly gives good results, provided that the patient's mental and motor status meet certain requirements. Adequate postoperative management and attention to certain minimum rules of care are major factors in the result. These patients must be followed over a long period of time for a maximum result to be obtained.
