摘要
背景:胫骨髓内钉远端螺钉的锁定对骨科医生来说,仍有一定的挑战,因为传统的徒手盲锁的失败率较高,辐射量大,且耗时长。目的:评价TRIGEN-SURESHOT导航系统下胫骨髓内钉远端锁钉的应用,并与徒手锁钉比较。方法:回顾性研究2014年5月至2015年8月安徽医科大学第二附属医院收治的胫骨干骨折45例,根据髓内钉远端锁钉运用技术不同分为2组,导航组(n=23)使用新型导航系统TRIGEN-SURESHOT进行髓内钉远端锁钉,徒手组(n=22)徒手锁定远端螺钉。结果与结论:全部患者均获得随访,随访时间为17-32个月。导航组髓内钉远端锁钉一次性成功率100%,显著高于徒手组(P<0.05)。导航组的远端锁钉时间显著少于徒手组(P<0.05)。且2组的骨折愈合时间、胫骨功能和并发症差异无显著性意义(P>0.05)。提示在胫骨髓内钉远端锁钉中应用TRIGEN-SURESHOT导航系统,效果令人满意,且锁钉时间短、成功率高、无辐射。
BACKGROUND：Positioning of the distal locking screws of a tibial intramedulary nail is often chalenging and time consuming. The traditional free-hand technique under fluoroscopic control involves considerable radiation exposure.OBJECTIVE： To evaluate the results of a new electromagnetic navigation system （TRIGEN-SURESHOT navigation system） for distal locking of tibial intramedullary nail in tibial diaphyseal fracture and to compare the effects with the free-hand method.METHODS： Forty-five cases of tibial diaphyseal fracture in the Second Hospital of Anhui Medical University from May 2014 to August 2015 were analyzed retrospectively, and were divided into two groups. Patients in navigation group （n=23） were treated with intramedullary nail using the TRIGEN-SURESHOT navigation system for distal locking, and the remainings in free-hand group （n=22） were given the free-hand method.RESULTS AND CONCLUSION： All cases were followed up for 17-32 months. The one-time success rate of distal locking nail operation was 100％ in the navigation group, which was significantly higher than that in the free-hand group （P 0.05）. To conclude, the effect of the TRIGEN-SURESHOT navigation system for distal locking of tibial intramedullary nail is satisfactory, exhibiting the advantages of short operation time, high success rate, and no radiation.
