The flexor hallucis longus is situated on the fibular side of the leg. It arises from the inferior two-thirds of the posterior surface of the body of the fibula, with the exception of 2.5 cm at its lowest part; from the lower part of the interosseous membrane; from an intermuscular septum between it and the peroneus muscles, laterally, and from the fascia covering the tibialis posterior, medially.
The tarsal tunnel is delineated by bone on the inside and the flexor retinaculum on the outside. People with TTS typically complain of numbness in the foot radiating to the big toe and the first three toes, pain , burning, electrical sensations, and tingling over the base of the foot and the heel.

The flexor digitorum longus runs along the medial posterior side of the lower leg and aids in flexions of the toes (apart from the big toe). The flexor digitorum longus muscle arises from the posterior surface of the body of the tibia, from immediately below the soleal line to within 7 or 8 cm of its lower extremity, medial to the tibial origin of the tibialis posterior muscle.

The flexor digitorum brevis or flexor digitorum communis brevis [1] is a muscle which lies in the middle of the sole of the foot, immediately above the central part of the plantar aponeurosis, with which it is firmly united. Its deep surface is separated from the lateral plantar vessels and nerves by a thin layer of fascia.
The flexor digiti minimi brevis (flexor brevis minimi digiti, flexor digiti quinti brevis) lies under the metatarsal bone on the little toe, and resembles one of the interossei. It arises from the base of the fifth metatarsal bone , and from the sheath of the fibularis longus ; its tendon is inserted into the lateral side of the base of the ...
Toe flexors are innervated by the tibial nerve. Toe extensors (extensor hallucis longus, extensor digitorum longus) are innervated by the deep peroneal nerve. Loss of normal adult descending pyramidal control of the reflex arc to suppress extensor withdrawal results in the upgoing toes in the plantar reflex known as Babinski's sign. [11]
Hallux rigidus or stiff big toe is degenerative arthritis and stiffness due to bone spurs that affects the metatarsophalangeal joints (MTP) at the base of the hallux (big toe). Hallux flexus was initially described by Davies-Colley [ 1 ] in 1887 as a plantar flexed posture of phalanx relative to the metatarsal head.
