Base of Thumb Arthritis Surgery
Overview
Base of thumb arthritis affects the joint at the base of the thumb, causing pain with pinching, gripping, opening jars, turning keys and using phones or tools. It is common and often starts with non-operative treatment such as splints, hand therapy, activity modification and injections.
When symptoms remain limiting, surgery can reduce pain and improve practical thumb function. Options include trapeziectomy with ligament reconstruction and tendon interposition, or selected joint replacement such as the Touch prosthesis.
Who may benefit from surgery?
Surgery may be considered for persistent pain, weakness, loss of pinch strength or daily limitations despite non-operative care. The best option depends on arthritis pattern, bone quality, adjacent joint involvement, activity demands and patient preference.
What does the procedure involve?
Trapeziectomy removes the arthritic trapezium bone. LRTI uses tendon tissue to stabilise and support the thumb base. Touch prosthesis replacement resurfaces the joint with an implant in suitable patients, aiming to reduce pain while preserving thumb mechanics.
Recovery after thumb arthritis surgery
Recovery takes time. Splinting protects the reconstruction or implant early. Hand therapy then restores motion, pinch mechanics, grip strength and dexterity.
Rehabilitation protocol
You will receive a trapeziectomy/LRTI or thumb joint replacement protocol matched to your procedure.
FAQs
When is surgery needed for thumb arthritis?
When pain and function remain unacceptable despite splints, therapy, medication or injections.
What is trapeziectomy and LRTI?
It removes the arthritic trapezium and uses tendon tissue to stabilise the thumb base.
What is the Touch prosthesis?
It is a thumb base joint replacement option for selected patients.
How long does recovery take?
Comfort and dexterity improve gradually over months.
Will pinch strength improve?
Pain relief often improves practical use, but strength recovery is gradual and varies.
