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.
