title: Promising one- to six-year results with the Motec wrist arthroplasty in patients with post-traumatic osteoarthritis.
abstract: The Motec cementless modular metal-on-metal ball-and-socket   wrist arthroplasty was implanted in 16 wrists with scaphoid nonunion   advanced collapse (SNAC; grades 3 or 4) and 14 wrists with scapholunate   advanced collapse (SLAC) in 30 patients (20 men) with severe (grades   3 or 4) post-traumatic osteoarthritis of the wrist. The mean age of   the patients was 52 years (31 to 71). All prostheses integrated   well radiologically. At a mean follow-up of 3.2 years (1.1 to 6.1)   no luxation or implant breakage occurred. Two wrists were converted   to an arthrodesis for persistent pain. Loosening occurred in one   further wrist at five years post-operatively. The remainder demonstrated close   bone-implant contact. The clinical results were good, with markedly   decreased Disabilities of the Arm Shoulder and Hand (DASH) and pain   scores, and increased movement and grip strength. No patient used   analgesics and most had returned to work. Good short-term function was achieved using this wrist arthroplasty   in a high-demand group of patients with post-traumatic osteoarthritis.
