Carpometacarpal Arthrodesis: Indications and Techniques.

Trapeziometacarpal arthrodesis is a beneficial surgery for young and higher-demand patients who have trapeziometacarpal arthritis. Surgical techniques can vary, but certain aspects of the surgery are critical, including bony preparation and positioning of the thumb in space. Reported outcomes are generally favorable, although the quality of evidence is poor. There are no comparison studies assessing different arthrodesis techniques, and only a few comparing arthrodesis to the trapeziometacarpal arthroplasty procedures. Most published results are case series with retrospectively collected data.
