What does CMC stand for in hand braces?

• A. Carpometacarpal
• B. Carpo-metacarpal
• C. Carpometacarpal joint capsule
• D. Carpo-metacondylar

Answer: (A)

CMC stands for carpometacarpal—the joints where the carpal bones of the wrist meet the bases of the metacarpal bones in the hand. This is the standard way the abbreviation is used in anatomy and in braces or clinical notes. A hyphenated form like carpo-metacarpal is a variant spelling, but carpometacarpal is the common, widely accepted term. Adding “joint capsule” turns the phrase into a description of a structure around the joint rather than the name of the joint itself, and carpo-metacondylar points to a nonstandard articulation in the hand. So the best choice is carpometacarpal.
