Spontaneous fusion of the hip following infection or surgical procedures can result in deformity that causes degenerative change in the associated joints. Loss of function can cause pain in adjacent joints. Conversion of hips fused in a deformed position to low-friction arthroplasty reduces shearing strain and improves walking function. Conversion of the fused hips constitutes a technically difficult procedure; adequate exposure with trochanteric osteotomy with the patient in the supine position is strongly advocated.
感染或手术后髋关节的自发融合可导致畸形，进而引起相关关节的退行性改变。功能丧失会导致相邻关节疼痛。将处于畸形位置融合的髋关节转换为低摩擦人工关节置换术可减少剪切力并改善行走功能。融合髋关节的转换是一项技术难度较大的手术；强烈建议在患者仰卧位时通过转子截骨术进行充分暴露。
