Abductor hallucis of the foot on the right side of the body.

The Abductor Hallucis is an intrinsic muscle of the foot located in Plantar Layer I. The muscles located in Plantar Layer I are:



  • Calcaneus to the big toe (toe #1).
    • The proximal attachment is onto the tuberosity of the calcaneus.
    • The distal attachment is onto the medial side of the base of the proximal phalanx of the big toe



  • Abducts the big toe at the metatarsophalangeal joint.
  • Flexes the big toe at the metatarsophalangeal joint.



  1. The abductor hallucis also has attachments into the plantar fascia of the foot.
  2. Strengthening the abductor hallucis in clients who have hallux valgus (a bunion) is important.
