Definition
The lateral head of the flexor hallucis brevis (FHB) is one of the two heads of the FHB muscle, the other being the medial head.
The lateral head of the FHB originates from the cuboid bone and the lateral cuneiform bone. It inserts into the lateral sesamoid bone and the base of the proximal phalanx of the hallux.
The insertion of the lateral head of the FHB is closely associated with the adductor hallucis muscle. Both the adductor hallucis (transverse and oblique heads) and the lateral head of the FHB share a conjoined insertion at the lateral sesamoid bone and the base of the proximal phalanx of the great toe.
