Origin[edit | edit source]
Most of extensor digitorum longus arises from the anterior surface of medial surface of fibula and the upper part of anterior surface of he interossous membrane, while small part of it 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 digit 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 inhibited Tibialis anterior, so stretch and myofascial release of the muscle and activate tibialis anterior to regain musccle balance.
