Anatomical terminology [ edit on Wikidata]

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

Structure

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

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