【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(P0.05)。导航组的远端锁钉时间显著少于徒手组(P0.05)。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(P0.05)。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。
[Abstract]:Background: the locking of distal screw of tibial intramedullary nail is still a challenge to orthopedic surgeons because of the high failure rate high radiation dose and time consuming of traditional blind locking. Objective: to evaluate the application of distal locking nail of tibial intramedullary nail under TRIGEN-SURESHOT navigation system and compare it with that of free hand nail. Methods: a retrospective study of 45 cases of tibial shaft fractures treated in the second affiliated Hospital of Anhui Medical University from May 2014 to August 2015 was carried out. A new navigation system, TRIGEN-SURESHOT, was used for the distal locking of intramedullary nail, and the unarmed group was used to lock the distal screw with bare hand. Results and conclusion: all patients were followed up for 17-32 months. The success rate of intramedullary nail in navigation group was 100%, which was significantly higher than that in bare hand group (P 0.05). The distal locking time in the navigation group was significantly less than that in the bare hand group (P 0.05). There was no significant difference in fracture healing time, tibial function and complications between the two groups (P 0.05). It is suggested that the application of TRIGEN-SURESHOT navigation system in distal locking nail of tibial intramedullary nail has satisfactory effect, short locking time, high success rate and no radiation.
