Clinical Trial Summary

Rhizarthrosis is a form of osteoarthritis that affects the trapeziometacarpal joint at the base of the thumb, which is more common in women over 50. Genetic and hormonal factors as well as the frequency of certain physical movements may contribute to its appearance. Surgical treatment is recommended if medical treatment fails, and trapezectomy is currently considered the standard method, although 3rd generation trapeziometacarpal prostheses are also available.

The aim of this study is to compare the clinical and radiographic results after surgical treatment of rhizarthrosis: prosthesis versus trapezectomy.

Description:

This is a two-center, randomized, prospective, comparative study.

The functional, clinical and radiographic evaluation in the early, medium and long term will make it possible to determine the possible superiority of arthroplasty if it exists.

The close evaluation of the patients during the first 3 months will make it possible to update the superiority of the arthroplasty on the functional recovery in the short term if it exists.
