Clinique Saint Jean, France
300 participants

INTERVENTIONAL
Conditions
Summary
The aim of this clinical trial is to assess the functional outcomes of isolated trapeziometacarpal joint arthroplasty in adult patients requiring surgical management of trapeziometacarpal osteoarthritis, with or without associated symptoms. The primary endpoint is the evolution of the Quick DASH functional score between inclusion (preoperative) and one year postoperatively. The study design is a follow-up study of a multicenter cohort.
Eligibility
Inclusion Criteria6
- Patient requiring surgical management
- Clinical and radiographic diagnosis of peri-trapezial osteoarthritis in the 1 or 2 joints:
- TM osteoarthritis: glickel sign + grinding test STT osteoarthritis: pain on wrist mobilization in flexion-extension and prono-supination
- TM (Eaton-Littler stages II to III) and STT (Crosby stages II and III) radiographic osteoarthritis
- Persistent pain and functional limitations despite conservative treatment for at least 6 months (combining intermittent immobilization of wrist and thumb + joint infiltration of the 2 joints)
- Ability to understand and sign the informed consent form.
Exclusion Criteria4
- History of surgery on the affected thumb.
- Systemic inflammatory diseases (e.g. rheumatoid arthritis).
- Active infection or history of joint infection of the upper limb.
