Anatomical Relations

The collateral ligaments of the interphalangeal joints are the strong fibrous bands that attach to each side of the interphalangeal joint, holding the joint firmly in place. They extend obliquely from the dorsal surface of the proximal phalanx to the palmar surface of the distal phalanx (Dorland, 2011).
