Spontaneous arthrodesis occurred after bilateral, extraarticular shelf augmentation and femoral varus osteotomies in a child with dislocated hips secondary to muscle imbalance from cerebral palsy. The proposed cause is heterotopic bone formation in the hip abductors in the face of insufficient range of motion exercise.
一名因脑瘫导致肌肉失衡而髋关节脱位的儿童，在接受双侧关节外髋臼造盖术和股骨内翻截骨术后出现了自发性关节融合。推测原因是在髋关节外展肌中，由于活动范围锻炼不足而出现异位骨形成。
