Dorsal carpometacarpal ligaments

Dorsal carpometacarpal ligaments

Anatomy

Strongest and most distinct carpometacarpal ligaments connecting the carpal and metacarpal bones on their dorsal surface of the hand.

The second metacarpal bone receives two fibrous bands from the trapezoid and trapezium bone. The third metacarpal receives two bands, one each from the trapezium and capitate bones. The fourth two, one each from the capitate and hamate. The fifth receives a single band from the hamate, and this is continuous with a similar ligament on the volar surface, forming an incomplete capsule.

Functions

Support and stability to the carpometacarpal joints.
