Name
- Deep Transverse Metacarpal Ligament (DTML)
- Deep Transverse Palmar Ligament
- Ligamentum metacarpeum transversum profundum
- Deep transverse ligament of the hand
- Transverse metacarpal ligament
- Intermetacarpal transverse ligament
- Deep intermetacarpal ligament
- Transverse palmar ligament
General
- Narrow fibrous band, runs across the volar surfaces of the heads of the 2-5 metacarpals
- Connects the palmar surface of the metacarpophalangeal joints providing stability[5]
- Does not include the thumb
- Blends with the palmer metacarophalangeal ligaments
- Volar surface is concave where the flexor tendons pass over it
- Behind it the tendons of the Interossei pass to their insertions.
