Collateral Ligament Injuries Information

Collateral Ligament Injuries


Collateral ligaments strengthen the sides of the fibrous capsule that surrounds the joints in the fingers and thumb – the metacarpophalangeal (MCP) joints, at the base of the fingers and thumb, the proximal interphalangeal (PIP) joints, nearest to the palm in the fingers, and the distalinterphalangeal (DIP) joints, the second joint in the fingers. The collateral ligaments provide medial-lateral stability.
