The deep transverse metacarpal ligament (also called the deep transverse palmar ligament) connects the palmar surfaces^{[citation needed]}ofmetacarpophalangeal joints of all the fingers of the hand except the thumb.^[1]

Structure[edit]

The deep transverse metacarpal ligament is a narrow fibrous band. It blends with the palmar metacarpophalangeal ligaments.

Its palmar surface is concave where the flexor tendons pass over it. Behind^{[clarification needed]} it, the tendons of the interosseous muscles of the hand pass to their insertions.^{[citation needed]}

Clinical significance[edit]

Rarely, the deep transverse metacarpal ligament may rupture.^[2]
