Trapeziometacarpal Dual Mobility Prostheses in Patients with Rheumatoid Disease: A Multicenter Retrospective Cohort Study

Background/Objectives: Trapeziometacarpal (TM) joint involvement is common in inflammatory rheumatic disease and may result in pain, instability, and functional impairment. Although TM arthroplasty is widely performed for primary osteoarthritis, evidence in patients with inflammatory arthropathy remains limited. This multicenter study evaluated clinical outcomes, complications, and revision rates of TM arthroplasty in patients with inflammatory rheumatic disease. Methods: We conducted a retrospective multicenter cohort study including patients with inflammatory rheumatic disease who underwent primary TM arthroplasty at tertiary referral centers. Demographic, clinical, radiographic, and surgical data were collected. Standard radiographs obtained at 1, 6, and 12 months postoperatively were reviewed to assess implant stability, radiolucent lines, and implant-related complications. Primary outcomes included revision rate and complications; secondary outcomes included functional recovery. Results: Fourteen patients undergoing 15 TM arthroplasties were included; one patient underwent bilateral surgery. The cohort was predominantly female (64%), with a mean age of 63 years. Mean clinical follow-up was 12.8 months (range, 12–18). Functional outcomes improved significantly following surgery, with substantial reductions in QuickDASH disability scores. One complication (1/15 procedures; 6.7%) occurred, consisting of a postoperative hematoma managed nonoperatively. No revision surgeries were required among 15 procedures during the available follow-up, corresponding to a revision rate of 0%. Conclusions: TM arthroplasty in inflammatory rheumatic disease was associated with satisfactory functional outcomes, a low complication rate, and no revision procedures during short-term follow-up, suggesting that TM arthroplasty may represent a potential option in carefully selected patients.
