The '''deep transverse metacarpal ligament''' (also called the '''deep transverse palmar ligament''') connects the palmar surfaces{{Citation needed|date=August 2023}} of [[Metacarpophalangeal joint|metacarpophalangeal joints]] of all the fingers of the hand except the thumb.'''<ref name=":022">{{Cite book |last=Sinnatamby |first=Chummy S. |title=Last's Anatomy |vauthors= |publisher= |year=2011 |isbn=978-0-7295-3752-0 |edition=12th |pages=91}}</ref>'''

The '''transverse metacarpal ligament''' is a narrow fibrous band, which runs across the volar surfaces of the heads of the second, third, fourth and fifth [[metacarpal]] bones, connecting them together.

== Structure ==

It is blended with the volar (glenoid) ligaments of the [[metacarpophalangeal]] articulations.

The deep transverse metacarpal ligament is a narrow fibrous band. It blends with the [[palmar metacarpophalangeal ligament]]s.

Its volarpalmar surface is concave where the [[Flexor]]flexor tendons pass over it;. behind{{Clarify|reason=Unclear what this means in this context (posteriorly/dorsally?)|date=August 2023|text=Behind}} it, the tendons of the [[Interosseiinterosseous muscles of the hand]] pass to their insertions.{{Citation needed|date=August 2023}}

Rarely, the deep transverse metacarpal ligament may rupture.<ref>{{Cite journal|last1=Wheatley|first1=Michael J.|last2=Layman|first2=Charles|last3=Ben Burke|first3=J.|date=May 1998|title=Closed rupture of the deep transverse metacarpal ligament: Diagnosis and management|url=https://doi.org/10.1016/S0363-5023(05)80472-1|journal=The Journal of Hand Surgery|volume=23|issue=3|pages=524–528|doi=10.1016/s0363-5023(05)80472-1|pmid=9620195|issn=0363-5023|url-access=subscription}}</ref>
