国人膝关节单髁表面置换假体的设计及临床应用

The prosthetic Design And Clinical Application of Unicompartmental Knee Prosthesis Suitable for Chinese

作者对40张CT片、20张X线片和在20具尸体上测量了膝关节的一些关键项目,发现胫骨平台宽度可作为决定假体尺寸的首要指标。这项研究吸收了国内外假体设计的经验,设计出适合国人的单髁型假体,已进行50例次单髁表面置换术,临床结果显示这种假体可以成功运用。

It has been proved that the geometric parameters or the knee joints are indispensable for the design of the knee prosthesis, Some key items of the knee were measured in this study from 40 CT photographes and 20 X -ray films as well as 20 cadaver leading index in determining the proschetic dimention of the knees, It was found that the width of the tibial condyle might be taken as the knees. The author of this study tied to design unicompart-mental knee prosthesis suitable for Chinese by absorbing the experience of abroad and domestic studies, 50 unicom-partmental knee replacements have been performed. The clinical results indicated that this kind of prosthesis could be successfully used.
