IMN与MIPPO对胫骨中下段骨折治疗效果及生物力学性能分析(1)
摘 要：目的 對比交锁髓内钉与微创经皮钢板内固定治疗胫骨中下段骨折的临床疗效及其生物力学性能。方法 选择2016年2月～2017年1月来我院治疗的胫骨中下段骨折患者152例，根据治疗方式分为两组。IMN组76例采用交锁髓内钉治疗，MIPPO组76例采用微创经皮钢板内固定治疗，观察两组患者术后1年踝关节Mazur评分优良率。另选择成人踝关节标本20具，随机分为两组，实验组10例采用IMN固定，对照组10例采用MIPPO固定，实现固定后取正、侧位拍X线片，开展三点弯曲、轴向压缩试验以及扭转强度试验，并比对两组数据。结果 IMN组和MIPPO组术后1年Mazur评分优良率相近，差异无统计学意义(P>0.05)。实验组弯曲偏移量、轴向压缩偏移量以及扭转角度均大于对照组，差异具有统计学意义(P<0.05)。结论 MIPPO与IMN两种术式治愈胫骨中下段骨折方面无明显优劣，MIPPO可减少手术创伤，但力学性能相对较差，临床应用时需明确各自手术适应症，合理运用。

Abstract：Objective To compare the clinical efficacy and biomechanical properties of interlocking intramedullary nail and minimally invasive percutaneous plate fixation in the treatment of middle and distal tibial fractures.Methods From February 2016 to January 2017，152 patients with middle and lower tibial fractures were divided into two groups.76 cases in IMN group were treated with interlocking intramedullary nail and 76 cases in MIPPO group were treated with minimally invasive percutaneous plate fixation.The excellent and good rate of Mazur score of ankle joint was observed one year after operation.Another 20 adult ankle specimens were randomly divided into two groups.10 cases in the experimental group were fixed with IMN and 10 cases in the control group were fixed with MIPPO.After fixation，the X-ray films were taken in both the forward and the lateral positions.Three-point bending test， axial compression test and torsional strength test were carried out，and the data of the two groups were compared.Results The excellent and good rate of Mazur score was similar between IMN group and MIPPO group one year after operation，the difference was not statistically significant(P>0.05).The bending offset，axial compression offset and torsion angle of the experimental group were greater than those of the control group，the difference was statistically significant(P<0.05).Conclusion MIPPO and IMN have no obvious advantages and disadvantages in the treatment of middle and lower tibiofibular fractures.MIPPO can reduce surgical trauma， but the mechanical properties are relatively poor.The clinical indications should be clear and appropriate., http://www.100md.com(付玉帅)
