Non-invasive analysis of wrist kinematics by four-dimensional CT scanning to improve both diagnosis and treatment of wrist injuries

Wrist injuries can lead to an unstable wrist joint, which untreated can lead to joint arthritis. Unfortunately, an unstable wrist joint is often missed on radiographs because the instability is visible on a moving wrist. A new technique is four-dimensional CT imaging (4DCT). In 4DCT, a series of 3D images of both moving wrists are obtained in just a few seconds. With this project, we aim to introduce 4DCT into the clinic to replace wrist arthroscopy, improving diagnosis and treatment and reducing patient collateral damage and healthcare costs.
