Abstract
The flexor hallucis longus (FHL) is a bipennate muscle that originates from the distal two-thirds of the posterior surface of the shaft of the fibula. It passes behind the medial malleolus, deep to the flexor retinaculum. The tendon courses through a fibro-osseous tunnel along the posterior surface of the talus and passes forward on the sole of the foot inside the fibro-osseous tunnel beneath the sustentaculum tali. A strong slip is given to the flexor digitorum longus and forms the master knots of Henry. It ends by inserting into the base of the distal phalanx of the great toe [1].
