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
In human anatomy, the metacarpal bones or metacarpus form the intermediate part of the skeletal hand located between the phalanges of the fingers and the carpal bones of the wrist, which forms the connection to the forearm. The metacarpal bones ar ...

It is blended 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.
