|Latin||Arteria plantaris medialis|
|Posterior tibial artery|
At the base of the first metatarsal bone, where it is much diminished in size, it passes along the medial border of the first toe, anastomosing with the first dorsal metatarsal artery. If the artery is burst along this route the possibility of blood excretion through the cuticle and backing up the artery causing a severe case of blood poisoning is high. A such burst should be considered a medical emergency.
Small superficial digital branches accompany the digital branches of the medial plantar nerve and join the plantar metatarsal arteries of the first three spaces.
A superficial branch which supplies a plantar digital artery to the medial side of the 1st toe, and a deep branch which assists in supplying blood to the plantar metatarsal arteries.
