【摘要】 目的 总结微创稳定系统(LISS)治疗胫骨下段骨折的外科经验和临床效果。方法 从2004年5月～2005年4月，用LISS治疗了7例胫骨下段骨折。5例为闭合性骨折，2例为开放性骨折。观察胫骨下段骨折的固定的稳定性、骨折愈合率和感染率。结果 所有病人平均持续随访1年，包括X线照片和膝关节功能的社会评分、医院专门外科评分。2例已在外院处理，骨折的变形被重新修复。全部病人被随访至骨折愈合。没有固定的丢失和骨折的不愈合，没有钢板和螺钉的变形，有软组织的感染。结论 LISS内固定系统在不需要额外保持骨折中间稳定的情况下，便能成功地治疗胫骨粉碎下段骨折，取得较好的功能结果和较低的并发症。LISS对于胫骨粉碎性下段骨折提供了稳定的固定、较高的愈合率、较低的感染率。这项技术成功运用新的外科原理，达到准确减少骨折对位不良的效果。

    【Abstract】 Objective To summarize the surgical experience and clinical results of the first 7 fractures of the distal of tibia treated with the Less Invasive Stabilization System (LISS).Methods From May 2004 to April 2005,7 patients with distal of tibia were treated with LISS fixation.There were 5 closed fractures and 2 open fractures.Obverse stable fixation,rate of union and infection for distal of tibial fractures.Results All patients were consecutive followed up an average of one year. included radiographs and clinical examinations using Knee Society scores and Hospital for Special Surgery scores for fractures of the distal with extraarticular and intraarticular fractures.Two patients treated by other hospital surgeons.Surgical reduction and fixation of fractures,followed by rehabilitation.Seven patients with fractures were followed until union.No loss of fixation and union. No reduction of plates and screws occurred in patients,no superficial wound infection and seromas.Conclusion The LISS internal fixator system can be used successfully to treat complex distal of tibia fractures without the need for additional medial stabilization.and good functional outcomes with a low complication rate.The LISS provides stable fixation,a high rate of union,and a low rate of infection for distal tibial fractures.The technique requires the successful use of new and unfamiliar surgical principles to effect an accurate reduction and acceptable rate of malalignment. ......
