Radiographical Analysis of the Normal Wrist

Abstract

Proper interpretion of wrist radiography requires a standardized radiographic technique. We obtained posteroanterior and lateral radiographs in 100 normal volunteers in standardized position (forearm in zero rotation) to analyze the normal wrist. We measured the carpal alignment and carpal height ratio, and the structural indeces of the distal end of the radius such as variancy, radial inclination and volar tilt. The average and standard deviation which was obtained in this study is a reliable index for Japanese.
