The deep transverse metacarpal ligament (also called the deep transverse palmar ligament) is a narrow fibrous band which runs across the palmar surfaces of the heads of the second, third, fourth and fifth metacarpal bones, connecting them together.

Structure

The deep transverse metacarpal ligament connects the palmar surfaces of the heads of the second, third, fourth, and fifth metacarpal bones. It is blended with the

palmar metacarpophalangeal ligament The metacarpophalangeal joints (MCP) are situated between the metacarpal bones and the proximal phalanges of the fingers. These joints are of the condyloid kind, formed by the reception of the rounded heads of the metacarpal bones into shallow cav ...

Clinical significance

Rarely, the deep transverse metacarpal ligament may rupture.
