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.

Who should consider this trial

Good fit: Ideal candidates are individuals over 45 years old with symptomatic trapeziometacarpal osteoarthritis who have not benefited from prior medical treatments.

Not a fit: Patients with significant anatomical issues, such as trapezium height less than 8 mm, or those with local infections or allergies to the surgical materials may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the most effective surgical treatment for thumb arthritis, potentially improving recovery outcomes for patients.

How similar studies have performed: While trapezectomy is a standard treatment, the comparative effectiveness of arthroplasty is less established, making this study a novel approach.
