Origin, lateral condyle of tibia, upper two thirds of anterior margin of fibula; insertion, by four tendons to the dorsal surfaces of the bases of the proximal, middle, and distal phalanges of the second to fifth toes; action, extends the four lateral toes; nerve supply, deep branch of peroneal.
Synonym(s): musculus extensor digitorum longus [TA] , long extensor muscle of toes.

The flexor and extensor tendons of both fingers were approximated to the corresponding flexor digitorum longus and extensor digitorum longus with interlacing suture.
We used 2 muscles from rat: soleus (which has a greater proportion of type I fibers, oxidative) and extensor digitorum longus (EDL, which has a greater proportion of type II fibers, glycolytic).

Currently, autologous donor tendons include the palmaris longus, plantaris, extensor indicis proprius, extensor digiti minimi, flexor digitorum superficialis, and extensor digitorum longus tendons [11-12].

Peroneus tertius, sometimes thought of as an offshoot of extensor digitorum longus, also should be considered an assistor of dorsiflexion, (27) though it is absent in (10.) 5% of individuals.
Ultrasound examination revealed more expressed changes in the extensor digitorum longus during lengthening of the congenitally shortened tibia, which was evident by a greater reduction in its thickness and increased echodensity (p < 0.05).
