1、临床医学论文•胫骨平台骨折术中下肢力线的,恢复与疗效分析【摘要】〔目的〕探讨胫骨牛台骨折术中下肢力线的恢复与疗效。〔方法〕自2000年5月〜2005年6月,45例胫骨平台骨折病人,其中男25例,女20例,平均45.3岁。骨折分型:SchatzkerI型3例,II型10例,ID型19例,IV型6例,V型5例,VI型2例,均行关节镜辅助下切开复位植骨钢板螺钉内固定,同时注意恢复正常的下肢力线。下肢力线的恢复以健侧为参照标准。测量方法:自骼前上棘至第1、2趾间拉一直线,计算離骨中心至该直线的垂直距离,并与健侧比较。〔结果〕45例患者40例获得随访,随访时间6〜24个月,平均15个月,按
2、Rasmussen膝关节评分标准,结果:优24例,良11例,可3例,差2例,优良率达87.5%,膝关节功能与下肢力线正常与否密切相关。部分病术后发生下肢力线的异常,其主要原因为:(1)半月板切除过多导致膝关节内载荷的重新分布;(2)患肢负重过早,使已复位的关节面再次塌陷;(3)骨折类型复杂,普通支持钢板难以达到骨折块之间的加压固定而造成骨折移位。〔结论〕术中下肢力线的纠正是膝关节功能恢复的重要保证,同时,要充分考虑导致术后下肢力线异常的主要因素并给予相应处理。【关键词】胫骨平台骨折;内固定;下肢力线Abstract:[Objective]Toinvestigatetheresto
