How is a CMC arthroplasty performed?

Thumb CMC arthroplasty involves removing the small wrist bone that is part of the CMC joint and replacing it with a wrist flexor tendon. During the procedure, a small incision (approximately 1.5 inches) is made over the CMC joint, and the trapezium wrist bone is removed.

How long does it take to recovery from CMC arthroplasty?

The first 6 weeks are tough with pain, weakness, and stiffness in the thumb. Most patients have minimal pain by 3 months after surgery. Your symptoms will continue to improve with improvements in ability to do more activities every 3 months.

Which tendon is used for CMC arthroplasty?

Description of Technique The thumb CMC joint arthroplasty is performed using an FCR tendon for ligament reconstruction combined with removal of the distal half of the trapezium, which is replaced with a life preserver-shaped spacer that is carved out of allograft cartilage.

Is CMC Arthroplasty the same as Lrti?

Ligament Reconstruction Tendon Interposition, or better known as LRTI, has been the traditional surgical treatment of Basal Joint Arthritis since the 1970s. The diseased trapezium bone is removed, and then typically the flexor carpi radialis tendon is cut.

Is LRTI the same as CMC arthroplasty?

What is LRTI? 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.

What tendon is used in Lrti surgery?

Trapeziectomy with ligament reconstruction and tendon interposition (LRTI) with the flexor carpi radialis (FCR) tendon is one of the most common procedures for the treatment of trapeziometacarpal osteoarthritis. We modified the LRTI, using the palmaris longus (PL) tendon instead of the FCR tendon.

What is arthrosis of the first CMC joint?

Arthrodesis of the CMC1 joint is a surgical procedure in which the trapezium bone and the metacarpal bone of the thumb are secured together. Because the joint is fixed, and therefore can not be moved, the complaints of the patient are mainly gone. During the surgery the two bones will be fixated using K-wires. The use of plates and screws has also been described.

What is CMC arthritis?

Carpometacarpal (CMC) arthritis is a form of osteoarthritis (OA). It is a slowlyprogressive degenerative disease at the base of the thumb joint as it attaches tothe wrist.

What is a CMC arthroplasty?

Carpometacarpal (CMC) arthroplasty reconstructs the thumb joint to address pain and inflammation, usually in a patient with arthritis. Older adults typically need this surgery as the wear and tear on the joint over the course of their lives eventually limits mobility and causes pain.

What is LRTI surgery and can it help treat arthritis?

LRTI stands for ligament reconstruction and tendon interposition . It’s a type of surgery for treating arthritis of the thumb, a common type of arthritis in the hand. Joints are formed where two bones meet. Your joints are lined with smooth tissue known as cartilage. Cartilage permits free movement of one bone against another.
