Radiology of Ligamentous Instability of the Wrist

Owing to the fact that the wrist connects the distal forearm to the hand, it is the final linkage involved in positioning the hand in space. Daily activities place great demand on the wrist, and wrist injuries can create tremendous disability. Understanding the mechanics of the wrist is important. The recent surge of interest in the wrist and in wrist instability has led to the development of many new operative procedures. Our ability to recognize and diagnose ligamentous instability of the wrist must keep pace with the skills of our orthopedic colleagues. As with most joint injuries, a more thorough understanding of the relevant anatomy is useful.
