Hand instrumentation for small joint arthroscopy.

This is the second in a series of articles on arthroscopy of small joints. Hand instrumentation for small joint arthroscopy has been adapted from instruments previously developed for large joint arthroscopy. They have been downsized and altered for use in the smaller confines of joints such as the radiocarpal, temperomandibular, and midcarpal articulations. Although smaller, the instruments must remain strong and easy to use. Each instrument should perform a simple function. Their shape must conform to the joint and they should be smooth to minimize the risk of articular cartilage damage. We have found several instruments that have been helpful in arthroscopic surgery of the wrist.
