[目的]评价Tri-Lock骨保留型股骨柄(Tri-Lock BPS)应用于初次全髋关节置换术的短期疗效.[方法]回顾性分析2013年3月～2014年1月四川大学华西医院骨科关节外科使用Tri-Lock BPS假体进行初次全髋关节置换术治疗髋关节疾患210例(228髋),对比手术前后Harris髋关节评分、生命质量SF-12量表评分,分析影像学结果,记录与股骨内置物相关的并发症.[结果]至末次随访时,188例203髋(89.04％)获得随访,平均随访时间(29.50±5.98)个月(24～36个月),Harris评分由术前平均(38.60±6.12)分提高至末次随访时的(98.07±2.88)分,差异具有统计学意义(P＜0.001);其中197髋(97.04％)优,6髋(2.96％)良,优良率100％;患者术前生命质量SF-12量表PCS:(28.44±4.38)分,MCS:(53.25±5.11)分,末次随访时PCS:(52.93±2.42)分,MCS:(60.47±1.72)分,差异具有统计学意义,(P＜0.001);203髋股骨假体影像学资料均评定为稳定骨长入,未发现股骨柄周围透亮线、假体周围骨溶解或假体松动及假体柄下沉超过3 mm病例,无死亡及翻修病例,1例1髋(0.50％)术中安放股骨假体时发生股骨距劈裂,5例5髋(2.46％)出现小腿肌间静脉血栓,4例4髋(2.00％)出现偶发性股区痛.[结论] Tri-Lock BPS假体初始稳定性佳,早期骨长入良好,短期应用疗效满意,长期效果有待于进一步随访观察.“,”[Objective] To investigate the short term results of Tri-Lock bone preservation stem (Tri-Lock BPS,DePuy,Warsaw,IN) in primary total hip arthroplasty.[Methods] A total of 210 patients (228 hips) received total hip arthroplasty with Tri-Lock BPS.The Harris score,SF-12 scoring system and radiological images were recorded and compared pre-and postoperatively.Complications related to the implantation were observed.[Results] After surgery,203 hips (89.04％) were available for the minimum of 24 months follow-up with a mean of (29.5±5.98) months (range,24-36months).The mean Harris hip score significantly improved from (38.60±6.12) preoperatively to (98.07±2.88) at the latest follow-up (P＜0.001).Additionally,the mean SF-12 score physical component summary (PCS) and mental component summary (MCS) scores noteworthily improved from (28.44±4.38) and (53.25±5.11) to (52.93±2.42) and (60.47±1.72) respectively (P＜0.001).All of the femoral components were clinically stable with radiographic evidence of bone ingrowth.In term of complications,femoral calcar fracture occurred in 1 hip (0.50％) as the prosthesis was been implanting,moreover,intramuscular veins thrombosis in 5hips (2.46％) and transitory thigh pain in 4 (2.00％)were found.No subsidence of the prosthesis more than 3 mm was noted in any patient and no femoral revisions was needed for any reason.[Conclusion] Total hip arthroplasty with the Tri-Lock BPS has good clinical and radiographic results at short-term follow-up.
