简要总结

The goal of this clinical trial is to learn if the surgical method with total joint arthroplasty, (TOUCH joint prosthesis), is as good as or better than the traditional surgical method, trapezectomy, to treat thumb base joint osteoarthritis.

The main questions it aims to answer are:

Does surgery with total joint arthroplasty provide better power grip and pinch grip strength compared to traditional surgery?

What is the long-term risk of complications for both methods?

Which method is more cost-effective for the healthcare system?

Researchers will compare total joint arthroplasty (TOUCH) to trapezectomy (a procedure where a bone in the thumb base is removed) to see which method provides the best results for the patient.

Participants will:

Be randomized to undergo either an operation with total joint arthroplasty or a trapezectomy.

Undergo an initial evaluation and a health economic cost analysis after one year.

Attend follow-up checkups at 2, 5, and 10 years post-surgery to evaluate long-term function and the durability of the prosthesis.

详细描述

Background and Rationale:

Basal joint arthritis of the thumb (trapeziometacarpal osteoarthritis) is a common condition causing pain and reduced hand function. While trapeziectomy with ligament reconstruction/capsuloplasty has long been a gold standard, total joint arthroplasty, such as the TOUCH prosthesis, has gained popularity. However, there is a lack of high-quality prospective randomized controlled trials (RCTs) comparing these methods regarding long-term functional outcomes, complication rates, and cost-effectiveness. This study aims to compare the clinical and health-economic outcomes of total joint arthroplasty with TOUCH prosthesis versus trapeziectomy with capsuloplasty.

Study Design and Randomization:

This is a prospective, randomized controlled trial. Following informed consent obtained by the attending surgeon, participants are randomized to either:

  1. Total joint arthroplasty using the TOUCH prosthesis.
  2. Trapeziectomy with capsuloplasty. Randomization is performed in close proximity to the day of surgery. Due to the nature of the interventions, participants are informed of the surgical method postoperatively.
