4DCT Imaging for DRUJ Injuries

Overview

About this study

The purpose of this study is to measure differences in distal radial-ulnar joint movement between injured and uninjured wrists using motion picture CT imaging (4DCT), with the hopes of establishing a less invasive diagnostic tool than arthroscopy. The belief is that the precise location and characteristics of the injury can be determined by measuring joint spacing during wrist rotation.
