Touch® Trapeziometacarpal Joint Arthroplasty
Touch® Trapeziometacarpal Joint Arthroplasty: The intervention involves primary trapeziometacarpal joint (TMJ) arthroplasty using the Touch® prosthesis, a dual-mobility implant designed for the treatment of osteoarthritis in the thumb.
Study summary
This study aims to develop a predictive model to help doctors better understand expected outcomes one year after thumb joint surgery for osteoarthritis. By analyzing clinical and patient-reported data from individuals who underwent surgery with the Touch® implant, the study seeks to predict pain levels and hand function 1-year after surgery. This information can support shared decision-making, set realistic expectations, and improve personalized treatment planning.

Primary outcome measure(s)
Pain During Activities at 1-Year Post-Surgery — 1 year after surgery Pain during activities will be measured using a Numeric Rating Scale (NRS) ranging from 0 (no pain) to 10 (maximum pain). Participants rate the level of pain experienced during typical daily activities.
Hand Function at 1-Year Post-Surgery — 1 year after surgery Hand function will be assessed using the brief Michigan Hand Outcomes Questionnaire (bMHQ), which evaluates hand performance in various activities. Scores range from 0 to 100, with higher scores indicating better function.
