What is CMC arthroplasty surgery?

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 many Carpometacarpal joints are there?

five CMC joints There are five CMC joints. The first CMC joint is located between the trapezium and the base of the first metacarpal. The second CMC joint is located between the trapezoid and the base of the second metacarpal. The third CMC joint is located between the capitate and the base of the third metacarpal.

Where is the 1st carpometacarpal joint?

The 1st CMC (carpometacarpal) joint is a specialized saddle-shaped joint at the base of the thumb. The trapezium carpal bone of the wrist and the first metacarpal bone of the hand form the 1st CMC or thumb basal joint.

What is the type of the 2nd 5th carpometacarpal joints?

The second and third joints are however essentially immobile and can be considered to have zero degrees of freedom in practice.

What type of joint is found between the first metacarpal and the trapezium?

saddle joint The first carpometacarpal joint of the thumb is particularly important; the articulation between the first metacarpal and the trapezium bone forms a saddle joint and allows a wide range of movement, including flexion, extension, abduction, adduction, circumduction and opposition of the thumb.

How many carpal bones are there?

Your wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm — the radius and the ulna. The most commonly injured carpal bone is the scaphoid bone, located near the base of your thumb.

Where is the trapezium bone?

At the base of the thumb is a small bone called the trapezium which, together with the metacarpal bone above, forms a joint called the carpometacarpal joint (CMCJ). Removal of the trapezium bone can reduce the pain and allow easier use of the thumb.

How many degrees of freedom does the 1st CMC joint have?

These two CMCs provide the other three CMCs with a fixed and stable axis. While the mobility of the fourth CMC joint is perceptible, the first joint is a saddle joint with 2 degrees of freedom, which except for flexion/extension, also enables abduction/adduction and a limited amount of opposition.
