Collateral Metacarpophalangeal Ligaments
Ligamenta metacarpophalangea collateralia
Read moreAnatomical Relations
The collateral metacarpophalangeal ligaments are the strong fibrous bands that attach to each side of the metacarpophalangeal joint, holding the joint firmly in place. They extend obliquely from the posterior tubercle on the lateral surface of the metacarpal heads to the lateral palmar aspect of the base of the proximal phalanx (Lourie, Gaston and Freeland, 2006).
Function
Each collateral ligament, along with the accessory collateral ligaments, act as primary stabilizers of the metacarpophalangeal joint.
