The medial thigh muscles of children with cerebral palsy often spasm or even contract, which makes the hip joint often in the adduction position, gradually causing the femoral neck shaft angle to increase, and the hip joint to valgus and subluxation. If this state continues untreated, it will eventually dislocate completely and lose the ability to walk independently.

Therefore, the muscles of the inner thigh should be completely relaxed now, including: adductor longus, adductor muscle, gracilis and medial hamstring; At the same time, hip abduction training is continued for a long time. Review every 3 months. If the trend of femoral head displacement cannot be controlled, proximal femoral varus osteotomy or even pelvic osteotomy is needed to stabilize the hip joint.
