摘要
目的评价磁力导航交锁髓内钉治疗胫骨干骨折的疗效,并与普通交锁髓内钉疗效进行比较。方法将62例胫骨干骨折患者分为两组:A组23例,使用磁力导航交锁髓内钉治疗;B组39例,使用普通交锁髓内钉治疗。记录两组远端2枚锁钉锁定成功时间,一次性锁定成功率及骨折愈合时间。用Kakar评分标准评价两组疗效。结果远端2枚锁钉锁定成功时间:A组(6.7±2.0)min,B组(12.5±2.2)min,两组差异有统计学意义(P<0.05);一次性锁定成功率:A组96%,B组77%,两组差异有统计学意义(P<0.05);骨折愈合时间:A组(16.7±1.8)周,B组(16.9±1.6)周,两组差异无统计学意义(P>0.05);Kakar评分优良率:A组91%,B组87%,两组差异无统计学意义(P>0.05)。结论磁力导航交锁髓内钉治疗胫骨干骨折疗效满意,与普通交锁髓内钉比较有定位准确、手术时间短、创伤小的优势。
Objective To evaluate the effect of magnetic navigation for interlocking intramedullary nailing in the treatment of tibial shaft fracture and compare it with the effect of common interlocking intramedullary nail.Methods 62 cases were divided into two groups.23 cases in group A were treated with magnetic navigation interlocking intramedullary nail and 39 cases in group B were treated with common interlocking intramedullary nail.Time consumption of successful distal nail locking,one-time locking ratio and fracture healing time in two groups were observed.Kakar score system was used to evaluate the effect of treatment in each group.Results The average time consumption of successful distal nail locking was 6.7±2.0 minutes in group A and 12.5±2.2 minutes in group B.There was statistical difference between two groups（P0.05）.The average one-time locking ratio A was 96% in group and 77% in group B.There was statistical difference（P0.05）.The average fracture healing time in group A was 16.7±1.8 weeks and 16.9±1.6 weeks in group B.There was no statistical difference（P0.05）.The excellent and good rate with Kakar score system was 91% in group A and 87% in group B.There was no statistical difference（P0.05）.Conclusions Good effect can be achieved in magnetic navigation interlocking intramedullary nail in the treatment of tibial shaft fracture,which has advantages of more accurate position,less operation time and less trauma compared with common interlocking intramedullary nail.
