摘　　要：目的:回顾性研究年龄55岁以下成年患者移位股骨颈骨折内固定治疗失败病例以提高对其治疗的重视。方法:2007年1月至2010年6月治疗55岁以下移位股骨颈骨折内固定术后失败患者18例,男13例,女5例;年龄27～55岁,平均(48.0±6.0)岁;空心钉治疗17例,髓内钉治疗1例。入院时诊断为股骨头坏死16例,骨不连合并股骨头坏死2例。结果:18例患者内固定术后至手术失败时间8～32个月,平均23个月。复位内固定术后Garden指数不佳;入院时髋关节Harris评分33～80分,平均(56.0±12.5)分。8例股骨头坏死病例和2例骨不连合并股骨头坏死病例接受了全髋关节置换术,5例股骨头坏死病例接受了表面髋关节置换术,3例虽然影像学有股骨头坏死征象但临床症状不明显,接受了保守治疗。所有行髋关节表面置换和全髋关节置换的病例术后随访12～53个月,平均34个月,术后Harris评分(94.0±3.0)分(89～96分)。结论:股骨头坏死是55岁以下成年移位股骨颈骨折闭合复位内固定术后常见并发症,必须提高对青壮年股骨颈骨折闭合复位内固定治疗的重视。Objective：To investigate the failure of internal fixation on displaced femoral neck fractures in adults under fifty-five years old retrospectively inorder to pay more attention to the treatment of these fractures. Methods： From Junary 2007 to June 2010,18 failed cases of internal fixation on displaced femoral neck fractures in adults under fifty-five years old were treated ,there were 13 males and 5 females with an average age of （48.0±6.0） years old ranging from 27 to 55. Among them, 17 patients were treated with cannulated screws and 1 patient was treated with intramedullary nail; 16 patients were diagnosed as osteonecrosis and 2 patients as osteonecrosis associated with nonunion. Results： The average time from internal fixation to failure was 23 months （ranged, 8 to 32 months）. The quality of fracture reduction in Garden index was poor. The Harris Hip Score was （56.0±12.5） （ranged, 33 to 80）. Eight cases of osteonecrosis and 2 cases of nonunion combinated osteonecrosis were received total hip arthroplasty. Hip resurfacing arthroplasty were performed for other 5 osteonecrosis. Because of no evident clinical symptoms, the other 3 cases received conservative treatment. The patients with total hip arthroplasty and hip resurfacing arthroplasty were followed-up for 34 months ranging from 12 to 53 months. After operation,the Harris score was （94.0±3.0） ranged 89 to 96. Conclusion：Osteonecrosis is a common complication after internal fixation on displaced femoral neck fracture in adults under fifty-five years old. More attention should be paid to the treatment of displaced femoral neck fracture in those patients.
