Origin

Four perforating branches arise from the distal ends of each of the four plantar metatarsal arteries.

Course

From their origins at the distal ends of the intermetatarsal spaces, the perforating branches of the plantar metatarsal arteries travel through the first to fourth intermetatarsal spaces and anastomose with the dorsal metatarsal arteries.

Branches

There are no named branches.

Supplied Structures

The perforating branches of plantar metatarsal arteries provide an arterial supply to the structures of the first to fourth intermetatarsal spaces and adjacent structures. They also aid in the formation of a collateral vascular supply to the metatarsal and phalangeal regions of the foot.

Artery

ScienceDirect image

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
