About Thumb Replacements

This website has been designed to be a resource for patients considering a thumb replacement. You may have had conservative treatment or an injection, and are considering your next step. You will have probably been offered a trapeziectomy, but there is an alternative: Carpometacarpal joint (CMCJ) arthroplasty, also known as a thumb replacement.

Which Thumb Replacement Prosthesis?

Thumb replacements are not a new invention. They have been available in the UK and Europe for over 25 years. However, new materials, improved instrumentation and a better understanding of implant design have led to the introduction of a modern generation of thumb replacement prosthesis.

Why Request the Touch® CMCJ?

The Touch® thumb replacement builds upon the successful heritage of ball-and-socket thumb prostheses, with the added advantages of improved range of movement, increased stability (lower risk of dislocation) and superior surgical instrumentation, significantly enhancing the accuracy of the procedure.
