Description[edit | edit source]
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.[1]
Origin[edit | edit source]
The Abductor Hallucis muscle originates from the medial process of calcaneal tuberosity, flexor retinaculum, and plantar aponeurosis.[1]
Insertion[edit | edit source]
It inserts on the medial aspect of the base of the proximal phalanx of large toe.[1]
Nerve[edit | edit source]
The Abductor Hallucis is supplied by the medial plantar nerve (S1 & S2), a terminal branch of the tibial nerve.[2]
Artery[edit | edit source]
The Abductor Hallucis is supplied by the medial plantar artery and the first plantar metatarsal artery.[2]
Function[edit | edit source]
Abductor Hallucis flexes and abducts the large toe at the metatarsophalangeal joint.[3]
Clinical relevance[edit | edit source]
As an intrinsic muscle of the foot, the Abductor Hallucis plays an important role in stabilising the medial longitudinal arch of the foot.[1]
