Surgical Treatment of Peri-trapezial Osteoarthritis Using Isolated Trapeziometacarpal Arthroplasty in Adults

What this Trial Is About

Researchers are evaluating the functional outcomes of isolated trapeziometacarpal joint arthroplasty in adults who need surgery for trapeziometacarpal osteoarthritis. This study is a follow-up of a multicenter group of patients and focuses on changes in the Quick DASH functional score from before surgery to one year after. The goal is to better understand how this surgery affects arm, shoulder, and hand function over time. The treatment involves isolated trapeziometacarpal arthroplasty with double mobility using either a MAIA or TOUCH prosthesis, depending on the surgeons preference. All surgeons follow the same operating steps to keep the procedures consistent. This approach is being studied in 300 patients with peri-trapezial osteoarthritis. Participants will be assessed before surgery and then at 3, 6, and 12 months after the operation. Researchers will measure patient satisfaction, complications, pain levels, grip and pinch strength, thumb and wrist movement, and joint hyperextension. X-rays will also be reviewed one year after surgery. The main focus is the change in arm and hand function measured by the Quick DASH score one year post-surgery.
