LISS系统治疗股骨远端骨折的临床疗效

目的 探讨微创固定系统(less invasive stabilization systems-LISS )治疗股骨远端骨折的临床疗效。方法 2011年8月至2014年9月,LISS组29例采取微创切口复位,放置LISS接骨板；取20例使用股骨远端解剖型钢板内固定治疗的患者为对照组,对手术时间、切口长度、术中出血量、骨折愈合时间、术后并发症进行比较分析。结果 经5~21个月随访(平均13个月),骨折均愈合。据Schatzker-Lambert评分,LISS组优良率达86.2%,高于解剖钢板对照组的65%。结论 微创固定系统(LISS)治疗股骨远端骨折具有切口小,软组织切开及骨膜剥离少,骨折弹性固定,对骨质疏松患者也能坚强固定,可早期进行膝关节功能锻炼,避免膝关节挛缩,钢板对骨膜影响小,血供破坏少,骨折感染率低,愈合率高,并发症少,同时操作简单、方便,治疗效果良好。

Treatment of Distal Femoral Fracture with Less Invasive Stabilization Systems

Objective To explore the clinical effects of Less Invasive Stabilization Systems-LISS in treatment of distal femoral fracture. MethodsIn August 2011 to September 2014, LISS group 29 cases take minimally invasive incision reduction, placed LISS bone plate; Take 20 cases using distal femur anatomic plate internal fixation treatment of patients as control group, the operation time, incision length, intraoperative blood loss, fracture healing time, postoperative complications for comparative analysis. Results After 5~21 months follow-up (mean 13 months), the fractures were healed. According to Schatzker - Lambert score, LISS group was 86.2%, 65% higher than that of anatomic plate in the control group. Conclusion LISS in treating distal femoral fractures with a small incision, less soft tissue slice and the periosteum stripping, elastic fracture fixation, also can strong fixation, in patients with osteoporosis can be knee early functional exercise, avoid the knee joint contracture, steel impact on the periosteum is small, less disruptive to blood supply, infection rate is low, high healing rate, fewer complications, at the same time, the operation is simple, convenient, good treatment effect.
