plantar arch

The plantar arch supplies the underside, or sole, of the foot.

In the weight-bearing leg it supports the plantar arch.

For the plantar arch spring mechanism to function fully, there must also be restricted rotation in the hind and front parts of the foot.

The plantar arch is a circulatory anastomosis formed from:

The plantar arch flattens, the solar concavity decreases in depth and heels spread.

It has been related to inadequate posterior tibial artery circulation and absence of plantar arch.

When present, it acts to plantar flex the fifth digit and supports the plantar arch.

High plantar arches (pes cavus deformity of the foot)

The plantar arch runs from the 5th metatarsal and extends medially to the 1st metatarsal (of the big toe).

Except for reinforcing the plantar arch, they contribute to plantar flexion and move the four digits toward the big toe.

Plantar arch: The plantar arch in the human foot has an elastic spring function that generates energy for running but not walking.

Adductor hallucis acts as a tensor of the plantar arches and also adducts the big toe and then might plantar flex the proximal phalanx.

The spring ligament, long plantar ligament, short plantar ligament, and plantar aponeurosis also support the plantar arch.

Arterio-arterial anastomoses include actual (e.g., palmar and plantar arches) and potential varieties (e.g., coronary arteries and cortical branch of cerebral arteries).

It then turns medialward to the interval between the bases of the first and second metatarsal bones, where it unites with the deep plantar branch of the dorsalis pedis artery, thus completing the plantar arch.

At the proximal parts of the interosseous spaces these vessels receive the posterior perforating branches from the plantar arch, and at the distal parts of the spaces they are joined by the anterior perforating branches, from the plantar metatarsal arteries.

The deep plantar artery (ramus plantaris profundus; communicating artery) descends into the sole of the foot, between the two heads of the first Interosseous dorsalis, and unites with the termination of the lateral plantar artery, to complete the plantar arch.
