Three-dimensional morphological measurement of proximal radius and its guiding significance for prosthesis design / 吉林大学学报(医学版)

ABSTRACT

Objective: To measure the morphological parameters of the radial head of the Chinese and compare with those of the Western population, and to provide the references for the design of the radial head prosthesis of the Chinese. Methods: The CT scan data of normal elbow from 130 Chinese cases were selected. All the data were scanned by using a 64-slice spiral CT scanner and reconstructed and measured on AW 4. 5 workstations. The angle between neck and shaft (neck and head (LNH), the maximum diameter of radial head (DlMAX). the minimum diameter of radial head (D2MIN). the maximum diameter of articular surface (D3MAX) and the maximum vertical depression depth (DD3). the angle between D3MAX and horizontal plane (Z'jS). the minimum diameter of articular surface (D4MIN) and the minimum vertical depression depth (DDI), and the angle between DlMIN and horizontal plane (
