This study examined early perioperative complications and subsidence following total hip arthroplasty (THA) with a short femoral stem. A retrospective review of 207 consecutive patients (247 hips) having undergone THA via the direct anterior approach produced only six perioperative complications: two intraoperative fractures, three perioperative femur fractures and one dislocation. Subsidence greater than 5 mm was observed in four hips but subsidence did not progress greater than 3 mm at the latest follow-up. Based on these results, cementless THA though the direct anterior approach with a short femoral stem provides a clinical and radiographic advantage while maintaining low complication rates.
本研究探讨了采用短柄股骨假体的全髋关节置换术(THA)围手术期早期并发症及假体下沉情况。对207例(247髋)经直接前路行THA的连续患者进行回顾性分析,结果显示仅出现6例围手术期并发症:2例术中骨折、3例围手术期股骨骨折和1例脱位。4髋出现假体下沉超过5 mm,但在最近一次随访时假体下沉未超过3 mm。基于这些结果,采用短柄股骨假体经直接前路行非骨水泥型THA在保持低并发症发生率的同时,具有临床和影像学优势。
