| Summary: | Purpose: Many prosthetic designs have been developed for treated trapeziometacarpal joint (TMJ) osteoarthritis (OA). The aim of the study was to analyze the clinical, functional, and radiological outcomes and complications of a specific dual-mobility prosthesis for TMJ OA to support the correct hand surgeon decision. Methods: Between January 2019 and January 2022, a retrospective study was conducted on a consecutive series of 14 patients affected by TMJ OA and treated with the implantation of TOUCH® dual mobility TMJ prosthesis (KeriMedical Switzerland-HQ, Geneve, Switzerland). The follow-up period was 12–36 months. Evaluation criteria included the trapeziometacarpal axis, the Visual Analogue Scale (VAS), the pulp-to-pulp modified pinch test, the Kapandji score, and the Michigan Hand Outcomes Questionnaire (MHQ). Results: Clinical, functional, and radiological improvements were found in all outcomes analyzed. The postoperative values of VAS and pulp-to-pulp modified pinch test were statistically significant (p < 0.05). A non-statistically significant postoperative improvement was found in the Kapandji score (p < 0.05). Regarding complications, only one EPL injury was found, but no infection or prosthetic dislocation. Conclusions: The use of a TOUCH® dual-mobility prosthesis for treating TMJ OA improved postoperative clinical, functional, and radiological outcomes with a lower rate of complications in a short-term follow-up. Level of evidence: IV. |
