Abductor Hallucis belongs to the superficial layer of the plantar foot muscles, alongside the Flexor Digitorum Brevis and Abductor Digiti Minimi. It contributes to the soft tissue prominence on the medial side of the sole.
It inserts on the medial aspect of the base of the proximal phalanx of large toe.
The Abductor Hallucis is supplied by the medial plantar nerve (S1 & S2), a terminal branch of the tibial nerve.
The Abductor Hallucis is supplied by the medial plantar artery and the first plantar metatarsal artery.
Abductor Hallucis flexes and abducts the large toe at the metatarsophalangeal joint.
As an intrinsic muscle of the foot, the Abductor Hallucis plays an important role in stabilising the medial longitudinal arch of the foot.
