Total Thumb Carpometacarpal Joint Arthroplasty: A Retrospective Functional Study of 28 MOOVIS Prostheses:

Background: Trapeziometacarpal prostheses have been used for more than 50 years in the treatment of first carpometacarpal joint arthritis. Even though this technique is more expensive than trapeziectomy, it has many advantages such as faster convalescence with better patient comfort and improved strength and range of motion. The aim of this study was to report the early functional results of a patient cohort treated with a dual mobility thumb carpometacarpal joint prosthesis. Methods: A retrospective study was performed to assess the functional results of 25 patients treated for trapeziometacarpal advanced osteoarthritis (Eaton and Littler stage III) with 28 MOOVIS prostheses. Preoperative and postoperative assessments included pain, range of motion, and pinch and grip strength. The average follow-up time was 27.5 months. Results: The mean pain score measured by a visual analog scale was 8 preoperatively and 1 postoperatively. The mean preoperative Kapandji opposition score was 7 and counter-opposition sc...
