| Anatomical terminology | |
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[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]
