Origin[edit | edit source]
Most of extensor digitorum longus arises from the anterior surface of the medial surface of the fibula and the upper part of anterior surface of the interosseus membrane, while a small part arises from the lateral tibial condyle.[1]
Insertion[edit | edit source]
It divides into four slips that insert into the proximal and distal phalanges of the lateral four digits of the foot. [1][2]
Nerve Supply[edit | edit source]
Deep peroneal nerve, a branch of the common peroneal nerve.(L4, L5)[1]
Action[edit | edit source]
Extends lateral four digits and dorsiflexes the ankle.
Extensor digitorium longus tends to be overactive and tight for an inhibited Tibialis anterior, so stretching and myofascial release of the muscle together with activation tibialis anterior is indicated to regain muscle balance.
