Comparing Recovery After Surgery for Rhizarthrosis in Adults 45 to 85 Years Arthroplasty Using HORUS Prosthesis Versus Trapezectomy

What this Trial Is About

Rhizarthrosis is a type of osteoarthritis that affects the joint at the base of the thumb and is more common in women over 50. Genetic and hormonal factors, along with certain repetitive movements, may contribute to this condition. When medical treatments do not work, surgery is recommended, with trapezectomy being the standard method, though newer prostheses are also available. This study compares the clinical and X-ray results after surgery using either a prosthesis or trapezectomy to see which offers better recovery and function. The study is a randomized and prospective comparison conducted at two centers. Participants will be assigned to one of two groups one receiving trapezectomy surgery and the other undergoing trapeziometacarpal arthroplasty with a device called HORUS, a bipolar prosthesis consisting of implants for the metacarpal and trapezium bones. The study includes close evaluations during the first three months and further follow-up to assess early, medium, and long-term outcomes. Participants will have their wrist function and pain assessed, including a primary outcome measure at 4 weeks. Evaluations include clinical and radiographic assessments over time to monitor recovery and function. The study is designed to observe differences in functional recovery and pain relief after the different surgical treatments, with participant involvement spanning the early post-surgery period and beyond to capture comprehensive results.
