== Structure ==

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

The deep transverse metacarpal ligament connects the palmar surfaces of the heads of the second, third, fourth, and fifth [[metacarpal bones]].<ref name=":0">{{Cite journal|last=Bade|first=Holger|last2=Schubert|first2=Markus|last3=Koebke|first3=Jürgen|date=1994-10-01|title=Functional morphology of the deep transverse metacarpal ligament|url=https://www.sciencedirect.com/science/article/pii/S0940960211804760|journal=Annals of Anatomy - Anatomischer Anzeiger|language=en|volume=176|issue=5|pages=443–450|doi=10.1016/S0940-9602(11)80476-0|issn=0940-9602}}</ref> It is blended with the [[palmar metacarpophalangeal ligament]]s.<ref name=":0" />

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

== Clinical significance ==

Rarely, the deep transverse metacarpal ligament may rupture.<ref>{{Cite journal|lastlast1=Wheatley|firstfirst1=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>
