胫骨近端的形态学测量与膝关节置换

Morphological measurements of the proximal tibia and knee replacement

背景:胫骨近端为膝关节假体构成的下半部分,胫骨近端是膝关节假体放置的底部位。目的:评价胫骨近端的形态测量在临床上膝关节置换中的重要性。方法:以"膝关节;假体;置换"为中文关键词,以"Knee;Prosthesis;replacement"为英文关键词。采用计算机检索1995-01/2011-10有关磁共振图像测量在临床上膝关节置换中假体旋转对线中应用的文章。结果与结论:胫骨近端的形态测量即胫骨近端的三维有限元模型、相关参数及角度、生物力学研究与膝关节假体选择及设计有着重要相关性。胫骨近端的形态测量有二维和三维测量,以三维测量法精确,测量胫骨平台宽和倾斜角度、胫骨内外侧平台前后径,所测量的数据在临床上均有应用意义。胫骨近端是膝关节假体放置的底位置,而胫骨近端的三维模型与假体模型底部行模拟对接,提高手术的成功。

BACKGROUND： The proximal tibia is the upper part of knee prosthesis composition and the bottom part of knee prosthesis position. OBJECTIVE： To evaluate the importance of the proximal tibial morphological measurement in clinical knee replacement. METHODS： With ＂knee; prosthesis; replacement＂ in Chinese and English as key words, a computer-based retrieval from January 1995 to October 2011 was performed for papers in terms of magnetic resonance imaging measurements on prosthetic rotational alignment in clinical prosthetic knee replacement. RESULTS AND CONCLUSION： The morphological measurement of proximal tibia includes three-dimensional finite element model, relevant parameters and angle, as well as biomechanics research, which is all closely related with the selection and design of the prosthesis. Morphometry of the proximal tibia can be divided into two-dimensional and three-dimensional measurements, and the later is more accurate to measure tibial plateau width and tilt angle, tibial anteroposterior diameter, these measurement data have great application prospect in the clinical practice. Proximal tibial is the bottom part of knee prosthesis position, while the proximal tibial three-dimensional models can simulate and dock prosthetic model bottom, thus improve the success of the operation.
