However, it had been also found many shortcomings such as broken nails, delayed healing and was modified in order to achieve better efficacy and reduce complications. The aim of the present study is to compare the efficacy of rotary self-locking intramedullary nails （RSIN） with that of interlocking intramedullary nails （IIN） in the treatment of long-bone fractures.展开更多
目的研制自锁式防旋自动滑动加压钉板(self-locking type pro-rotary auto-sliding&compression nail plate,LPSC-NP)用于股骨颈骨折内固定,对其进行生物力学性能测试,为临床应用提供依据。方法采集18具新鲜成年股骨近端标本,制成...目的研制自锁式防旋自动滑动加压钉板(self-locking type pro-rotary auto-sliding&compression nail plate,LPSC-NP)用于股骨颈骨折内固定,对其进行生物力学性能测试,为临床应用提供依据。方法采集18具新鲜成年股骨近端标本,制成股骨颈骨折,分别用LPSC-NP、3枚空心钉、双头中空加压螺纹钉、动力髋螺钉内固定,并进行生物力学测试,用SPSS统计软件对实验数据进行分析。结果LPSC-NP的承载能力和抗扭转强度、刚度均明显大于后三者。结论LPSC-NP固定股骨颈骨折牢固可靠,符合生物力学要求。该器械结构合理,简单适用,有一定的临床价值。展开更多
目的:比较人工髋关节置换(total hip arthroplasty THA)与防旋型股骨近端髓内钉(proximal femoral nail anti-rotation PFNA)两种方法治疗高龄股骨转子间骨折患者的效果。方法:利用THA及PFNA方法共治疗年龄大于80岁的股骨转子间骨折患者...目的:比较人工髋关节置换(total hip arthroplasty THA)与防旋型股骨近端髓内钉(proximal femoral nail anti-rotation PFNA)两种方法治疗高龄股骨转子间骨折患者的效果。方法:利用THA及PFNA方法共治疗年龄大于80岁的股骨转子间骨折患者126例,THA治疗80例,PFNA治疗46例,比较两组患者的手术时间,术中出血量,术后下床时间,住院天数,Harris评分,术后1年死亡率、并发症发生率。结果:THA组在手术时间、术中出血量、术后下床时间、住院天数、Harris评分优良率,术后1年死亡率、并发症发生率上均明显优于PFNA组,经统计学分析有显著差异。结论:THA治疗高龄股骨转子间骨折的疗效优于PFNA。展开更多
