旋入式自锁髓内钉与交锁髓内钉治疗成人肱骨干骨折疗效分析

Comparative study of clinical outcomes of rotary self-locking intramedullary nail and intramedullary interlocking nail for the treatment of adult humeral shaft fractures

目的:比较旋入式自锁髓内钉与交锁髓内钉固定成人肱骨干骨折的疗效。方法:52例成人肱骨干骨折患者,22例患者采用旋入式自锁髓内钉固定(A组);30例患者采用交锁髓内钉内固定(B组)。分析两种治疗方法的手术时间、术中出血量、骨折愈合时间、肩关节功能及并发症。结果:A组平均手术时间为47min,术中平均出血量50ml,明显低于B组平均手术时间为70min,术中平均出血量125ml,差异有统计学意义(P<0.05)。A组Neer肩关节功能评分平均92分,优良率为93.3%;B组平均分为91分,优良率为90.5%,两组比较差异无统计学意义(P>0.05)。结论:旋入式自锁髓内钉治疗成人肱骨干骨折,操作简单,手术时间短,创伤小,效果好。

Objective： To compare the clinical effect of rotary self-locking intramedullary nail（RSIN） and intramedullary interlocking nail（IIN） in treating adult humeral shaft fractures. Methods： 52 cases of adult humeral shaft fractures, 22 patients were treated with RSIN（group A）; 30 patients were treated with IIN（group B）. The two groups were observed and compared on operation time, blood loss, fracture healing time, functional recovery and surgical complications. Results： the average operation time of group A was 47 min, the average amount of bleeding during the operation was 50 ml, significantly lower than that in B group, the mean operation time was 70 min, the average a mount of bleeding during the operation was 125 ml, the difference was statistically significant（P〈 0.05）. Group A Neer shoulder functional score was 92, the excellent and good rate was 93.3%; in group B, the average score was 91, the excellent and good rate was 90.5%, the difference was not statistically significant（P〉0.05）. Conclusion： Screw in treatment of adult humeral shaft fracture, self-locking intramedullary nail has the advantages of simple operation, short operation time, less trauma, good effect.
