Abstract
Total joint replacement has certain advantages over other surgical treatment methods for osteoarthritis of the thumb carpometacarpal joint, including restoration of thumb length and alignment, good cosmetical result, fast recovery of hand function and prevention of iatrogenic complications at neighbouring joints.Disadvantages include the technical difficulty to perform this surgery and a possible higher complication rate.A meticulous surgical technique is mandatory.Combined with a cementless and modular ball-in-socket implant with a metal-on-polyethylene friction couple, a 10-year survival rate higher than 90% can be expected.Revision surgery is possible with implant exchange or conversion to trapeziectomy.
