Between February 1987 and October 2008, we performed 102 total hip arthroplasties (THAs) after failed internal fixation of a prior hip fracture. There were 39 intertrochanteric fractures and 63 femoral neck fractures. Etiology of failure included 35 cases of osteonecrosis, 32 cases of arthritis, 25 cases of early failure of fixation, and 10 cases of nonunion. There were 12 patients who had early surgical complications related to the procedure (11.8%, 12/102). These included 5 patients who had dislocations (4.9%), 4 periprosthetic fractures (3.9%), 2 hematomas (2.0%), and 1 infection (1%). Of these 102 THAs, 50 were available for at least 2 years of follow-up (mean, 3.2 years). At a minimum 2-year follow-up, THA after failed internal fixation of hip fracture in these patients was clinically successful with an elevated risk of periprosthetic fracture and dislocation.
1987 年 2 月至 2008 年 10 月，我们对先前髋部骨折内固定失败后进行了 102 例全髋关节置换术（THA）。其中 39 例为转子间骨折，63 例为股骨颈骨折。失败的病因包括 35 例骨坏死、32 例关节炎、25 例固定早期失败和 10 例骨不连。有 12 例患者与手术相关出现早期手术并发症（11.8%，12/102）。其中包括 5 例脱位（4.9%）、4 例假体周围骨折（3.9%）、2 例血肿（2.0%）和 1 例感染（1%）。这 102 例 THA 中，50 例至少随访 2 年（平均 3.2 年）。在至少 2 年的随访中，这些患者髋部骨折内固定失败后行 THA 临床结果成功，但假体周围骨折和脱位的风险增加。
