Description[edit | edit source]
Flexor hallucis longus is a powerful muscle located on the posterior aspect of the fibular below the deep fascia of the calf. In its own synovial sheath, the tendon passes downwards, deep to the flexor retinaculum, crossing the posterior ankle joint, lateral to flexor digitorum longus.
Origin[edit | edit source]
Lower two-thirds of posterior fibula.
Insertion[edit | edit source]
Plantar surface at the base of the first distal phalanx
Nerve[edit | edit source]
Branch of the tibial nerve (root S1 and S2).
Cutaneous supply from root S2.
Artery[edit | edit source]
Peroneal artery[1]
Function[edit | edit source]
Flexes the phalanx of the great toe as the foot is raised from the ground. Additionally stabilises the first metatarsal head and keeps distal pad of the great toe in contact with ground in toe-off and when on tip-toe.[1]
Clinical relevance[edit | edit source]
Assessment[edit | edit source]
Palpation[edit | edit source]
It is near impossible to locate the origin due to it's depth to the soleus muscle. The insertional tendon is also deep but can be identified as it passes alongside the sustentaculum tali.
