目的：分析对比微创内固定系统（ LISS ）与单切口双钢板支撑内固定治疗复杂胫骨平台骨折的临床疗效。方法选择雅安市雨城区人民医院2012年1月至2014年1月收治的46例复杂胫骨平台骨折患者作为研究对象，分为试验组和对照组各23例，试验组接受LISS内固定治疗，对照组接受单切口双钢板支撑内固定治疗。通过对比两组患者的骨折愈合时间、膝关节功能、住院时间和不良反应发生率来分析其临床效果。结果试验组骨折愈合时间、膝关节功能、住院时间均明显优于对照组，差异有统计学意义（ P<0.05）；试验组不良反应发生率为8.70%，对照组不良反应发生率为21.74%，差异有统计学意义（ P<0.05）。结论在治疗复杂胫骨平台骨折时，ISS内固定治疗法的疗效显著，不良反应发生率低，患者满意率高，推荐在临床治疗中使用。“,”Objective To analyze and compare the clinical effects of less invasive stabilization system( LISS)and single in-cision bilateral buttress plate on complex tibial plateau fracture. Methods Selected 72 patients with complex tibial plateau frac-ture who received the treatment from January 2012 to January 2014,and divided them into the experimental group and observation group,with 23 cases in each group based on different treatment methods. The experimental group received the treatment of LISS, and the observation group was implemented single incision bilateral buttress plate. The healing time of fracture,knee score,hos-pital stay and adverse effects rate was analyzed. Results The healing time of fracture,knee score and hospital stay of experimen-tal group were better than the control group,and the differences were statistically significant(P<0. 05). The adverse effects rate of experimental group was 8. 70% and the adverse effects rate of control group was 21. 74%;the difference was statistically sig-nificant(P<0. 05). Conclusion Patients with complex tibial plateau fracture should be treated with LISS,as it has significant effect,lower adverse effects rate and higher satisfaction degree. So the use of complex tibial plateau fracture is recommended in the clinical treatment.
