摘要

目的 利用三维数字化重建和逆向工程技术,将LISS钢板与国人股骨远端重建模型匹配,并测量螺钉钉道参数,并探索一种个性化钢板固定手术方法。  方法 选自内蒙古医学院第二附属医院影像科非膝关节疾患成人CT连续扫描数据15例,共30侧(股骨大转子下缘至胫骨上1/3,年龄18~41岁,平均32岁),通过将重建钢板和螺钉导入Mimics10.01系统中与重建股骨远端进行配准,测量钢板钉孔位置上螺钉钉道长并检测钢板与股骨远端骨面贴附状况。  结果 螺钉钉道长度逐渐增大;重建股骨与钢板贴附实验中,左侧5例不能贴附,右侧7例不能贴附。  结论 LISS钢板固定股骨中远端,钉道由上到下逐渐增长,其长度有规律可循,现有产品规格与国人股骨远端解剖参数尚存在一定差异,需进一步改良。

Abstract

Objective To provide a basis on operation of distal femoral fracture by measuring screw canal parameters of distal femoral fixation using digital 3D skill and reverse engineering. Methods 15 adult cases (CT data came from the second affiliated hospital of Inner Mongolia medical college, without knee joint illness, extending from the lower of greater trochanter of femur to the upper 1/3 of tibia, ranging from 18~41 years, averagely 32 years old)were 3D reconstructed, including nail canal digital simulation and fixation. Results For 3D model of distal femur, the canal of screws gradually increased. 5 cases were not fit in left and 7 cases in right. Conclusions The screw canal, which is less invasive stable system for distal femur, is regular, with the gradually increased length. The parameters of LISS are differ from anatomic features of Chinese distal femur, and the improvement of LISS is necessary.
