MIPO技术以LISS/LCP联合同种异体骨治疗复杂胫骨平台骨折的疗效及其对HSS膝关节功能的影响

Curative effect of MIPO with LISS/LCP and allogeneic bone in the treatment of complex tibial plateau fracture and the influence on HSS knee function

目的:探究微创钢板内固定(MIPO)技术以微创内固定系统(LISS钢板)或锁定加压钢板(LCP)联合同种异体骨治疗复杂胫骨平台骨折的临床疗效,分析其对膝关节功能评分(HSS)的影响。方法:105例复杂胫骨平台骨折患者根据不同治疗方式分为观察组(n=56)和对照组(n=49),对照组接受MIPO技术以LISS/LCP治疗,观察组接受MIPO技术以LISS/LCP联合同种异体骨治疗。比较两组围术期指标、术后恢复情况、HSS评分和并发症发生情况。结果:观察组手术时间、骨折愈合时间、负重时间短于对照组,术中出血量少于对照组(P<0.05)。术后6个月、末次随访时,观察组的HSS评分高于对照组(P<0.05)。两组的并发症总发生率比较,差异无统计学意义(P>0.05)。结论:MIPO技术以LISS/LCP联合同种异体骨治疗复杂胫骨平台骨折具有良好疗效,不仅可加快术后恢复和骨折愈合,还能促进患者膝关节功能恢复。

Objective:To investigate the clinical effect of minimally invasive plate osteosynthesis(MIPO)with less invasive stabilization system(LIS plate)or locked compression plate(LCP)and allogeneic bone in the treatment of complex tibial plateau fracture,and analyze the influence on the hospital for special surgery(HSS)knee function.Methods:105 patients with complex tibial plateau fracture were divided into observation group(n=56)and control group(n=49)according to the different treatment methods.Patients in control group were treated with MIPO using LISS/LCP,and those in observation group were treated with MIPO using LISS/LCP and allogeneic bone.Perioperative indicators,postoperative recovery,HSS score and the incidence of complications were compared between the two groups.Results:The operation time,fracture healing time and weight-bearing time of observation group were shorter than those of control group,and intraoperative blood loss was less than that of control group(P<0.05).The HSS scores of observation group at 6 months after operation and at the last follow-up were significantly higher than those of control group(P<0.05).There was no significant difference in the total incidence of complications between the two groups(P>0.05).Conclusion:MIPO with LISS/LCP and allogeneic bone is effective in the treatment of complex tibial plateau fracture,which can not only promote postoperative recovery and fracture healing but also promote the recovery of knee function.
