The Abductor Hallucis Origin, Insertion, Action
Origin: Flexor retinaculum, the medial process of the calcaneal tuberosity, the plantar aponeurosis, and the intermuscular septum between it and flexor digitorum brevis
Insertion: Medial side of the base of the proximal phalanx of the great toe, with some of its fibers attaching more proximally to the medial sesamoid bone
Actions: Assists with flexion of the four small toes
Innervation: Medial plantar nerve (S1, S2)
Blood Supply: Lateral plantar artery from the posterior tibial artery
Primary Actions of the Abductor Hallucis
1. Abduction of the great toe at the metatarsophalangeal joint
- Agonists: None
- Antagonists: Adductor Hallucis
