Transverse metatarsal ligament
The transverse metatarsal ligament is a narrow band which runs across and connects together the heads of all the metatarsal bones; it is blended anteriorly with the plantar ligaments of the metatarsophalangeal articulations.
Its plantar surface is concave where the Flexor tendons run below it; above it the tendons of the Interossei pass to their insertions.
Its homologue in the hand is the transverse metacarpal ligament, which connects the metacarpals to each other.
