摘要
The process of constructing a database of average cross-sections in Chinese proximal femurs is described. The main goal of creating the database is for designing hip stems for Chinese patients. Methods for constructing the database are introduced. According to some existing software and programs developed by the authors, a database of average cross-sections in Chinese proximal femurs was built based on CT images of eighty femur-specimens. 3-D shape of a patient's proximal femurs can be reconstructed according to the database and X-ray radiographs. Theoretical analyses and results of clinical application indicate that the database can be used to design hip stems for Chinese patients.
描述了在股骨近端构建一个平均截面数据库的过程 .建立这个数据库主要是为中国人设计髋关节假体 .同时 ,介绍了构建数据库的方法 .根据现有的软件及开发的程序 ,建成了一个中国人股骨近端平均截面数据库 .该数据库是根据 80根股骨样本的CT图像建成的 .根据该数据库及X线片 ,可以重建中国患者股骨近端 3 D形状 .理论分析和临床结果表明 ,利用该数据库可为中国人设计髋关节假体 .
