trapeziectomy
Surgical removal of the trapezium bone, typically performed for thumb carpometacarpal arthritis treatment.
Full Definition
Trapeziectomy is a surgical procedure involving complete removal of the trapezium bone, most commonly performed as treatment for advanced thumb carpometacarpal (CMC) arthritis. The procedure eliminates the arthritic joint surface and can be performed alone or in combination with various reconstruction techniques including ligament reconstruction with tendon interposition (LRTI), joint fusion, or prosthetic replacement. Simple trapeziectomy removes only the bone, while trapeziectomy with LRTI involves using tendon grafts to maintain thumb length and stability. The procedure typically provides good pain relief but may result in some loss of thumb strength and pinch power. Recovery involves immobilization followed by progressive therapy to restore function.
Usage
Usage note: Specify whether simple trapeziectomy or combined with reconstruction; avoid confusion with trapezoidectomy.
