摘要：

背景：人工关节大多根据西方人种设计，与国人股骨近段髓腔存在一定差异。
目的：通过CT测量股骨近段横断面的髓腔内径参数，为设计符合国人的髋关节假体提供数据。
方法：通过CT对61例初次行全髋关节置换成年人的健侧股骨近段进行扫描，连续扫描3层，层厚均2 mm，测量股骨颈平面、股骨小转子平面、股骨峡部平面的髓腔内径等参数。
结果与结论：股骨峡部平面的各径线之间、股骨颈平面的宽径与内侧径之间、股骨小转子平面的长径与内侧径之间都存在着显著相关性(P< 0.05)。股骨颈平面的长径、宽径、内侧径及股骨峡部平面的皮质厚度在男女之间差异具有显著性意义 (P < 0.05)。所测3个平面的径线可为该类型股骨假体的设计提供数据支持。

Abstract:

BACKGROUND: Prostheses designed for Western is not very suitable for Chinese proximal femur.
OBJECTIVE: To provide reference for prosthesis design for Chinese based on the dimensions of proximal femur measured from CT films.
METHODS: The dimensions were measured at the neck, lesser trochanter and isthmus of the femur from 61 patients by CT films.
RESULTS AND CONCLUSION: There was a correlation among the three dimensions of the femoral isthmus, between wide-dimension and medial-dimension of the femoral neck, and between long-dimension and medial-dimension of the lesser trochanter of the femur (P < 0.05). There was a difference between men and women in wide-dimension, long-dimension, medial-dimension of the femoral neck and cortical thickness of the femoral isthmus. Measurement data of the proximal femur could provide reference for prosthesis design.
