The flexor hallucis longus (FHL) muscle is one of the muscles of the posterior deep compartment of the leg and along with flexor hallucis brevis muscle, is involved in flexion of the hallux (great or first toe). Its tendon passes between the medial and lateral tubercles of the talus. Its tendon sheath may communicate with the posterior ankle joint capsule.
Summary
- origin: distal 2/3 of fibula
- insertion: base of distal phalanx of hallux
- action: flexes all joints of the big toe and assists in plantarflexion
- arterial supply: peroneal artery (peroneal branch of the posterior tibial artery)
- innervation: tibial nerve (from sciatic nerve (roots S1 and S2))
- antagonist: extensor hallucis longus
