Objective To investigate the clinical effects of two minimally invasive surgical treatment(closed reduction and intramedullary nall ifxation and locking compression plate ifxation) of tibial shaft fractures.Methods 84 cases of tibial shaft fractures were selected as research subjects and divided into treatment group (Interlocking intramedullary nall treatment) and control group(Compression plate ifxation) according to treatment method, 42 cases in each group.Results Excellent rate of treatment group(97.62%) was slightly higher than that of control group(92.86%), which had no signiifcant difference and statistically signiifcant(P>0.05). The incidence of postoperative complications of treatment group(4.76%) was signiifcantly lower than that of the control group(23.81%), which had statistically signiifcant(P<0.05).Conclusion In the clinical treatment of tibial shaft fracture, the two treatments have similar clinical effects. However, interlocking intramedullary nall treatment is more in line with mechanics, has fewer postoperative complications and more conducive to healing patients, which is worthy popularizing.%目的：探讨闭合复位交锁髓内钉内固定与锁定加压钢板内固定两种微创手术方法治疗胫骨干骨折的临床效果。方法选取84例胫骨干骨折作为研究对象，根据治疗方法分为治疗组（带锁髓内钉治疗）与对照组（加压钢板治疗）各42例。结果治疗组的治疗优良率为97.62%，略高于对照组的92.86%，差异不明显，无统计学意义（P＞0.05）；治疗组的术后并发症发生率为4.76%，显著低于对照组的23.81%，有统计意义（P＜0.05）。结论在胫骨干骨折的临床治疗过程中，两种治疗方法的临床效果相似，但带锁髓内钉治疗更符合力学原理，术后并发症更少，更有利于患者的骨折愈合，值得推广。
