A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to compare the clinical and radiographic outcomes of two surgical treatments for rhizarthrosis: trapezectomy and arthroplasty. Conducted at two centers, it will evaluate functional recovery in patients over 45 years old who have not responded to medical treatment. Patients will be closely monitored for three months post-surgery to assess the short-term benefits of each procedure. The study seeks to determine if arthroplasty offers superior recovery compared to the standard trapezectomy.
