To explore the surgical strategy of traumatic osteoarthritis of the hip joint secondary to the failure of open reduction and internal fixation (ORIF) treatment on acetabular fractures.
Eighteen cases of traumatic osteoarthritis of the hip joint received total hip arthroplasties from May 2002 to December 2009, who had undergone the surgery of ORIF after acetabular fractures. There were 12 male and 6 female with an average age of 53 years (45 to 66 years). It was average 11.2 months (6.0 to 24.0 months) from the present of pain and limp to the operation. It was average 35 months (8 to 72 months) from ORIF procedure on acetabular fracture to total hip arthroplasty. Harris score was 50 points in average (26 to 70 points).
All 18 cases were followed up 40 months in average (12 to 86 months). They were allowed to get out of bed on 1 week after the operation. The time of full weight bearing lagged to 2 or 3 months after the operation. All patients had the function of their hips improved with Harris score of 86 points in average (80 to 92 points).
The procedures of ORIF on acetabular fracture make lots of trouble to total hip arthroplasty. It is important to rebuild the normal biological mechanisms of acetabulum and uses uncement fixed prosthesis as possible as it can.
探讨髋臼骨折切开复位内固定（ORIF）治疗失败继发创伤性髋关节骨关节炎的手术策略。
2002年5月至2009年12月，18例髋臼骨折切开复位内固定术后继发创伤性髋关节骨关节炎患者接受全髋关节置换术。其中男性12例，女性6例，平均年龄53岁（45至66岁）。从出现疼痛和跛行至手术平均时间为11.2个月（6.0至24.0个月）。从髋臼骨折切开复位内固定手术至全髋关节置换术平均时间为35个月（8至72个月）。Harris评分平均为50分（26至70分）。
18例患者均获随访，平均随访40个月（12至86个月）。术后1周允许下床活动。完全负重时间延迟至术后2至3个月。所有患者髋关节功能均有改善，Harris评分平均为86分（80至92分）。
髋臼骨折切开复位内固定手术给全髋关节置换术带来诸多困难。重建髋臼正常生物力学机制并尽可能使用非骨水泥固定假体很重要。
