The authors reported the case of a 27-year-old man who sustained an irreducible postero-lateral traumatic dislocation of the hip with capsular and labral entrapment. Initial X-rays showed only a small acetabular fragment. After two attempts to reduce the hip with muscle paralysis under general anaesthesia failed, the patient was treated by immediate open reduction through a postero-lateral approach. Surgical exploration of the hip revealed a small osteochondral fragment attached to a large piece of labrum and capsule, clogging the acetabulum. The femoral head crossed over the torn capsule with a buttonhole effect. These elements were relieved, the bone fragment was fixed with a 2 mm screw and the capsule was repaired. At the 10-year follow-up, the functional outcome was excellent with a Harris score of 100 points and no signs of necrosis or osteoarthritis. The authors propose a literature review of this uncommon lesion.
作者报告了一例27岁男性病例，该患者发生了不可复位的创伤性髋关节后外侧脱位，并伴有关节囊和盂唇嵌顿。最初的X线片仅显示一个小的髋臼碎片。在全身麻醉下尝试两次肌肉松弛复位髋关节均失败后，患者通过后外侧入路立即进行切开复位治疗。对髋关节进行手术探查发现，一个小的骨软骨碎片附着在一大块盂唇和关节囊上，堵塞了髋臼。股骨头以纽扣孔效应穿过撕裂的关节囊。这些情况得到缓解，骨碎片用一枚2毫米螺钉固定，关节囊进行了修复。在10年随访时，功能结果极佳，Harris评分为100分，无坏死或骨关节炎迹象。作者建议对这种罕见病变进行文献综述。
