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.[1] It contributes to the soft tissue prominence on the medial side of the sole.[2]
Origin[edit | edit source]
The Abductor Hallucis muscle originates from the medial process of calcaneal tuberosity, flexor retinaculum, and plantar aponeurosis.[2]
Insertion[edit | edit source]
It inserts on the medial aspect of the base of the proximal phalanx of large toe.[2]
Nerve[edit | edit source]
The Abductor Hallucis is supplied by the medial plantar nerve (S1 & S2), a terminal branch of the tibial nerve.[3]
Artery[edit | edit source]
The Abductor Hallucis is supplied by the medial plantar artery and the first plantar metatarsal artery.[3]
Function[edit | edit source]
Abductor Hallucis flexes and abducts the large toe at the metatarsophalangeal joint.[1]
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.[2]
