Anatomy

The Adductor Hallucis Muscle is composed of two heads: the oblique head and the transverse head. The oblique head originates from the bases of the second, third, and fourth metatarsals and the sheath of the peroneus longus muscle. The transverse head originates from the plantar metatarsophalangeal ligaments of the third, fourth, and fifth toes. Both heads insert into the lateral side of the base of the proximal phalanx of the big toe.

Function

The primary function of the Adductor Hallucis Muscle is to adduct the big toe. It pulls the big toe towards the center line of the body or towards the second toe. This muscle also assists in maintaining the arch of the foot and provides stability during walking and running.

Clinical Significance

Abnormalities or injuries to the Adductor Hallucis Muscle can result in conditions such as hallux valgus, commonly known as a bunion. This condition is characterized by a lateral deviation of the big toe and can cause pain and difficulty in walking.
