Abstract

INTRODUCTION

Anatomical study of 11 radii heads was done.

METHOD

A screw which is 2 mm longer than radial head diameter was used. Five views (AP with the forearm in supination, neutral rotation, pronation and LAT view the arm in supination and neutral rotation) were taken. In all cases the screw penetration was detected in one or two of the anteroposterior views. The lateral views were not sensitive to detect the screw penetration. For intraoperative assessment of screw length, the anteroposterior views in different position of rotation is sensitive method to detect penetration of the open reduction of head radius. Anteroposterior and lateral view with the arm in same position can miss some case of screw penetration. The diameter of the radial head was assessed.

RESULT

A difference in the radial head diameter between males and females was noticed. This can be reflected on the screw diameter.

摘要

介绍

对 11 个桡骨小头进行了解剖研究。

方法

使用比桡骨小头直径长 2 毫米的螺钉。拍摄五个视图（前臂旋前的前后位、中立位、旋前位和 LAT 位，手臂旋前和中立位）。在所有情况下，螺钉穿透都在一个或两个前后视图中检测到。侧位视图对检测螺钉穿透不敏感。对于术中评估螺钉长度，在不同旋转位置的前后视图是检测桡骨小头切开复位螺钉穿透的敏感方法。在同一位置的前后位和侧位片可能会漏诊一些螺钉穿透的病例。评估了桡骨小头的直径。
