abductor hallucis

abductor hallucis

a muscle that forms the medial margin of the foot and contributes to a soft tissue bulge on the medial side of the sole. It abducts and flexes the great toe at the metatarsophalangeal joint and is innervated by the medial plantar branch of the tibial nerve.

abductor hallucis

first plantar layer intrinsic foot muscle
  • origin flexor retinaculum and medial calcaneal tuberosity

  • insertion into the plantar medial area of hallux proximal phalanx

  • nerve supply medial plantar nerve

  • action deviation of hallux at the first metatarsophalangeal joint toward the midline/sagittal plane of the body (away from the midline of the foot); it tends to function as a hallux auxiliary plantarflexor in cases with hallux abductovalgus

As the phalanx becomes misaligned, the abductor hallucis can contribute to pronation while the extensor hallucis longus becomes an adducting force on the phalanx, promoting progression of the deformity (Fig.
