【摘要】：目的探讨电磁导航交锁髓内钉远端锁钉技术治疗股骨干骨折的早期临床效果。方法 2012年7月-2013年10月,收治53例股骨干骨折。其中男40例,女13例;年龄16~52岁,平均38.3岁。致伤原因:交通事故伤28例,高处坠落伤11例,摔伤7例,挤压伤4例,其他伤3例。开放骨折3例,均为GustiloⅠ度损伤;闭合骨折50例。骨折位于股骨上段17例,中段29例,下段7例。骨折按Winquist分型:Ⅰ型7例,Ⅱ型8例,Ⅲ型22例,Ⅳ型16例;按AO分型:32-A型18例,32-B型28例,32-C型7例。受伤至手术时间3~11 d,平均5 d。均采用电磁导航下远端交锁髓内钉植入治疗。结果 53例交锁髓内钉的远端锁钉均在电磁导航下完成,远端锁钉一次成功率达100%;锁钉时间5.0~9.5 min,平均7.0 min。术后患者切口均Ⅰ期愈合,无皮肤坏死、感染、窦道形成等术后早期并发症发生。53例均获随访,随访时间5~12个月,平均9个月。1例出现臀部疼痛、臀中肌肌力减弱,取出髓内钉后症状消失。随访期间无断钉、退钉、感染、再骨折、外展肌无力、异位骨化等并发症发生。骨折均获临床愈合,愈合时间8~22周,平均14.5周。术后8个月随访49例患者,Lys holm评分获优44例,良4例,可1例,优良率98%。结论电磁导航系统定位精度高、锁钉时间短、无辐射、安全可靠,应用该系统行远端交锁髓内钉植入可取得较好的早期临床效果。
[Abstract]:Objective to investigate the early clinical effect of electromagnetic navigation interlocking intramedullary nail in the treatment of femoral shaft fracture. Methods from July 2012 to October 2013, 53 cases of femoral shaft fractures were treated. There were 40 males and 13 females, aged 16 to 52, with an average of 38.3 years old. The causes of injury were as follows: traffic accident injury in 28 cases, fall injury in 11 cases, fall injury in 7 cases, crush injury in 4 cases, and other injuries in 3 cases. There were 3 cases of open fractures, all of which were Gustilo 鈪，
