Obturator dislocation of the hip is an extremely rare injury. Urgent closed reduction is critical to prevent complications such as avascular necrosis. We report a rare case of a 52-year-old woman who sustained an obturator dislocation following a motor vehicle collision. Manual reduction was successfully performed under fluoroscopic guidance with the hip positioned in flexion, abduction, and external rotation within 3 h post-injury. The patient followed a staged rehabilitation protocol and recovered well with only mild residual discomfort at 6 months. This case highlights the importance of early diagnosis, prompt reduction, and the utility of alternative reduction strategies when standard techniques fail. Long-term monitoring is advised due to the risk of femoral head collapse and subsequent osteoarthritis.
髋关节闭孔脱位是一种极其罕见的损伤。紧急闭合复位对于预防诸如缺血性坏死等并发症至关重要。我们报告一例罕见病例,一名52岁女性在机动车碰撞后发生髋关节闭孔脱位。在受伤后3小时内,在透视引导下将髋关节置于屈曲、外展和外旋位成功进行了手法复位。患者遵循分阶段康复方案,6个月时恢复良好,仅遗留轻度不适。该病例强调了早期诊断、及时复位的重要性,以及在标准技术失败时替代复位策略的实用性。鉴于存在股骨头塌陷及随后发生骨关节炎的风险,建议进行长期监测。
