Abstract：
UNASSIGNED: Irreducibility is a rare complication of pure posterior hip dislocation requiring surgical intervention.
UNASSIGNED: We present a case of a 22-year-old female with posterior hip dislocation following a motor vehicle accident. Despite unsuccessful closed reduction attempts, open surgical reduction successfully released the incarcerated muscles and achieved reduction. Follow-up examinations showed excellent functional outcomes without complications.
UNASSIGNED: Irreducibility remains a rare complication of traumatic posterior hip dislocation. Three possible entities can cause soft tissue incarceration: labral buttonholing, intra-articular osteochondral bodies, and entrapment of the piriformis muscle. The posterior-lateral approach provides excellent exposure of the posterior hip structures, but it carries the risk of injury to the medial circumflex artery. After successfully reducing the dislocation, it is essential to perform a computed tomography (CT) scan to detect any osteochondral lesions, including femoral head impaction. Functional outcomes are better with early mobilization and prompt resumption of weight-bearing. However, femoral head osteonecrosis complicates 52.9 % of hip dislocations reduced beyond 6 h, whereas it occurs in only 4.8 % of dislocations reduced within this timeframe.
UNASSIGNED: This case underscores the importance of prompt recognition and appropriate surgical intervention for irreducible hip dislocations to prevent further complications and optimize patient outcomes.

摘要：
■不可复性是需要手术干预的纯髋关节后脱位的罕见并发症。
■我们介绍了一例22岁女性在机动车事故后发生后髋关节脱位的病例。尽管封闭还原尝试不成功，开腹手术复位成功地释放了嵌顿的肌肉并实现了复位。随访检查显示良好的功能结果，无并发症。
■不可复性仍然是创伤性髋关节后脱位的罕见并发症。三种可能的实体可以导致软组织嵌顿:唇扣眼,关节内骨软骨体，梨状肌的压迫.后外侧入路可很好地暴露后髋关节结构，但它有损伤内侧回旋动脉的风险。成功减少位错后，必须进行计算机断层扫描（CT）扫描以检测任何骨软骨损伤，包括股骨头撞击。早期动员和迅速恢复负重，功能结果会更好。然而,股骨头坏死并发症52.9%的髋关节脱位减少超过6小时，而它只发生在4.8%的位错减少在这个时间范围内。
■该病例强调了及时识别和适当的手术干预对于预防更多并发症和优化患者预后的重要性。
