Carpo metacarpal arthroplasty or CMC arthroplasty is a type of surgery in which a bone at the base of your thumb is replaced with an implant. The joint where your thumb meets your hand is...
CMC joint arthroplasty is a surgical procedure used to replace the trapezium bone of the thumb joint with a tendon graft, or a silicone or metal implant to treat carpometacarpal joint osteoarthritis after conservative treatments fail to relieve symptoms.
Patients with advanced disease who have failed conservative treatment modalities have multiple surgical options including ligament reconstruction, resection arthroplasty, silicone implantation, tendon interposition, or total joint arthroplasty.
There are several options for the surgical treatment for arthritis of the thumb CMC joint. One type of surgery, called CMC Arthroplasty, involves reconstructing the joint. The surgery may be done as an outpatient procedure or may require an overnight stay at the hospital.
CMC arthroplasty can involve a tendon transfer, a total joint replacement, a suture, or temporary wire.
Most activities that involve grasping or pinching are possible because of the thumb’s remarkable range of motion. But dexterity comes at a price – an increased risk of osteoarthritis (OA) in the first carpometacarpal (CMC) joint, where the thumb meets the trapezium bone in the wrist.
Background Thumb arthritis at the carpometacarpal (CMC) joint is one of the most common sites of arthritis, especially in women. Thumb arthroplasty is an effective method of relieving pain and improving function.
LRTI (ligament reconstruction and tendon interposition) is a surgical procedure that is most commonly conducted to treat thumb CMC (carpometacarpal) arthritis where the damaged joint surfaces are removed and replaced with a cushion of tissue that keeps the bones separated.
When the cartilage shock absorber wears away, surgeons may recommend an arthroplasty to remove and replace the joint with a skin graft or an artificial implant made out of silicone, metal, or pyrocarbon.
Implant arthroplasty is an alternative option to trapeziectomy (with or without ligament reconstruction) for the treatment of thumb carpometacarpal (CMC) osteoarthritis (OA).
