文题释义:
带锁髓内钉:髓内钉已逐步成为治疗下肢长骨干骨折的金标准,带锁髓内钉属中心固定,相对钢板固定,有其独特的优势,应力分布更加均匀,强度更高,对骨膜血供破坏更少,且远端锁钉具有抗旋转、抗弯曲的特点。
TRIGEN-SURESHOT导航系统:利用电磁定位装置,3个线圈定义3个空间方向,将信号转化成图像,实时显示到屏幕上,方便操作,无需C型臂X光机透视。主要由3部分组成:显示器、探针和瞄准器,将探针插入髓内钉,显示器上会动态显示出瞄准器的方向和角度,待2个正圆重合且位于模拟的髓内钉远端锁孔 ,提示钻孔位置最佳,这时钻头刚好穿过锁孔,测深后可顺利置入螺钉。该系统操作简单,准确度高,无辐射。
 
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。

Abstract:

BACKGROUND: Positioning of the distal locking screws of a tibial intramedullary nail is often challenging and time consuming. The traditional free-hand technique under ?uoroscopic 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). The locking nail time in the navigation group was significantly less than that in the free-hand group (P < 0.05). No significant differences were found in the incidence of adverse events and fracture healing time between two groups (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.
