Flexor hallucis longus muscle

The Flexor Hallucis Longus Muscle is a muscle located in the lower leg that is involved in the flexion of the big toe. It is one of the three deep muscles of the posterior compartment of the leg, the other two being the Flexor Digitorum Longus and the Tibialis Posterior.

Anatomy[edit | edit source]

The Flexor Hallucis Longus originates from the lower two-thirds of the posterior surface of the fibula and the adjacent interosseous membrane. It is inserted into the base of the distal phalanx of the big toe. The muscle is innervated by the tibial nerve and receives its blood supply from the posterior tibial artery.

Function[edit | edit source]

The primary function of the Flexor Hallucis Longus is to flex the big toe. It also assists in plantar flexion and inversion of the ankle.

Clinical significance[edit | edit source]

Injury to the Flexor Hallucis Longus can result in a loss of ability to flex the big toe and can affect walking and running. It is also a common site of tendonitis in ballet dancers and athletes.
