Thumb arthritis and CMC joint replacement
Pain at the base of the thumb can make gripping, opening containers or turning a key difficult. Assessment helps establish whether the thumb’s carpometacarpal (CMC) joint is responsible and which treatment fits your needs.
Assessment and non-surgical options
Examination and, when needed, X-rays help assess the joint. An arthritic appearance on an X-ray does not by itself mean surgery is necessary. Activity changes, a thumb support, appropriate pain relief and sometimes an injection can help control symptoms. BSSH: basal thumb arthritis.
When is joint replacement considered?
Persistent pain and functional difficulty despite suitable non-surgical care may lead to a discussion about surgery. Options include trapeziectomy and, for selected patients, joint replacement. Touch is one implant used for thumb CMC replacement; it is not suitable for every thumb. The decision depends on joint anatomy, bone quality and your activity needs. Ask why a particular operation is recommended for you. Frimley Health: CMC joint replacement.
Recovery and limitations
A dressing or splint protects the thumb initially, followed by guided hand therapy and gradual return to use. Strong pinching and lifting need to wait until your team advises they are safe. Recovery takes time; an early movement video does not show final strength or predict another patient’s result. Sherwood Forest Hospitals: rehabilitation.
Risks include infection, stiffness, altered sensation and persistent pain. A replacement may also loosen, dislocate or need revision. Discuss implant-specific risks and alternatives before deciding. Frimley Health: risks and aftercare.
