摘　　要：目的回顾性评价可视化磁力导航系统在胫骨髓内钉远端锁钉过程中的作用,并与常规瞄准器方法进行比较,探讨应用磁力导航技术进行髓内钉远端锁钉的效果。方法选取2010年2月至2011年4月,我科收治的应用可视化磁力导航系统进行髓内钉远端锁钉操作的67例胫骨干骨折患者作为研究组,同期应用瞄准器进行锁钉操作的60例作为对照组进行回顾性研究。其中研究组,男40例,女27例。左侧30例,右侧37例,平均年龄(37.4±3.8)岁。AO分型:A型33例,B型19例,C型15例。对照组男37例,女23例,左侧28例,右侧32例,平均年龄(39.2±4.1)岁。AO分型:A型29例,B型14例,C型17例。两组分别应用可视化磁力导航系统和常规瞄准器对远端锁钉过程进行导航。记录并比较两组远端锁钉操作时间、锁钉次数、锁定过程透视次数,患者骨折愈合时间。结果研究组锁钉操作时间为(6.1±1.4)min,透视次数为0次、锁钉次数为69次,骨折愈合时间为(15.3±2.1)周;对照组手术操作时间为(8.3±2.4)min,平均透视次数为(4.05±2.2)次,锁钉次数为71次,愈合时间为(15.9±2.8)周。两组间锁钉操作时间、透视次数、锁钉次数差异有统计学意义(P<0.05),骨折愈合时间差异无统计学意义(p>0.05)。结论可视化磁力导航系统应用于髓内钉的远端锁钉过程,可以有效提高锁钉成功率、缩短锁钉操作时间,显著降低医患双方的放射线暴露,与常规的瞄准器方法相比更具优势,是髓内钉导航技术发展的新的方向。Objective To retrospectively evaluate the effects of visual magnetic navigation system in the distal locking process of tibial intramedullary nail, to compare the effects with that of the conventional matched target device, and to investigate the effects of magnetic navigation system in the distal locking process of intramedullary nail. Methods From February 2010 to April 2011, 67 patients with tibial shaft fractures who were adopted by our department andtreated with the visual magnetic navigation systemin the distal locking process of intramedullary nailwere selected as the research group, while in the same period 60 patients was treated with the matched target device in the locking process were taken as the control group. The research results were retrospectively analyzed. There were 40 males and 27 females in the research group, with a mean age of （ 37.4±3.8 ） years old. 30 fractures were on the left side, while 37 on the right side. According to the AO classiifcation, there were 33 cases of type A, 19 cases of type B and 15 cases of type C. In the control group, there were 37 males and 23 females with an average age of （ 39.2±4.1 ） years old. 28 fractures were on the left side, while 32 on the right side. According to the AO classiifcation, the type A, type B and type C fractures in the control group were in 29, 14 and 17 cases respectively. The visual magnetic navigation systemwas applied in the distal locking process in the research group, and the conventional matched target devicewas applied in the control group. The time for the distal locking process, the number of screw placements, the number of lfuoroscopy and the fracture healing timein the 2 groups were recorded and compared. Results Thetime for the locking process inthe research group was （ 6.1±1.4 ） min, the number of lfuoroscopy was 0, the number of screw placements was 69, and the fracturehealing timewas （ 15.3±2.1 ） weeks. The time needed for the locking processin the control group was （ 8.3±2.4 ） min, the average number
