| Anatomical terminology | |
The deep transverse metacarpal ligament (also called the deep transverse palmar ligament) connects the palmar surfaces 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 it, the tendons of the interosseous muscles of the hand pass to their insertions.
Clinical significance
Rarely, the deep transverse metacarpal ligament may rupture.[2]
