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及其与普通交锁髓内钉疗效比较。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 A组远端2枚锁钉锁定成功时间平均6.7±2.0min，B组12.5±2.2min，两组差异有统计学意义（P＜0.05)；A组一次性锁定成功率96%，B组77%，两组差异有统计学意义（P＜0.05)；A组骨折愈合时间平均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。相比普通交锁髓内钉有定位准确，手术时间短，创伤小的优势。马鞍山市人民医院骨科谢洋

Abstract： Objective  To evaluate the effect of magnetic navigation interlocking intramedullary nail 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 in group A is 6.7±2.0 minutes and 12.5±2.2 minutes in group B. There is a statistical difference between two groups（P＜0.05). The average one-time locking ratio in group A is 96% and 77% in group B. There is a statistical difference（P＜0.05). The average fracture healing time in group A is 16.7±1.8 weeks and 16.9±1.6 weeks in group B. There is no statistical difference（P＞0.05). The excellent/good rate was 91% in group A with Kakar score system and 87% in group B. There is no statistical difference（P＞0.05). Conclusions  Good effect was achieved in magnetic navigation interlocking intramedullary nail in the treatment of tibial shaft fracture, which has advantage of more accurate position, less operation time and less trauma compared with common interlocking intramedullary nail.
