Adductor hallucis is a two-headed, intrinsic muscle in the sole of the foot. There are three foot plantar muscle groups, the lateral, medial and central. The adductor hallucis belongs to the medial group.
The muscle that leads the big toe toward (the other toes).
Although the Adductor Hallucis belongs to the medial plantar group, it is located in the foot’s central compartment and it makes up the third layer of the plantar muscles in the foot, along with the flexor hallucis brevis and flexor digiti minimi brevis.
Oblique head: bases of metatarsal bones 2-4, cuboid bone, lateral cuneiform bone, tendon of fibularis longus.
Transverse head: plantar metatarsophalangeal ligaments of toes 3-5, deep transverse metatarsal ligaments of toes 3-5.
Lateral aspect of base of proximal phalanx of great toe.
1st Metatarsophalangeal joint: Toe adduction, toe flexion.
Support of longitudinal and transverse arches of foot.
Lateral plantar nerve (S2, S3).
Medial plantar artery, lateral plantar artery, plantar arch, plantar metatarsal arteries.
Hallux varus is a deformity that can present secondary to the release of the soft tissues surrounding the first metatarsophalangeal joint surfaces, including the adductor hallucis, during bunion surgery.

There is evidence in the research that when hallux valgus is present there is a muscular imbalance between the abductor hallucis and adductor hallucis. To strength the foot intrinsic muscles and therefore prevent or correct this deformity, the short-foot (SF) or toes-spread-out exercises should be performed.
