Description[edit | edit source]
The extensor digitorum longus is 1 of 4 muscles in the anterior compartment of the lower leg. The other muscles in the anterior compartment include: tibialis anterior, extensor hallucis longus, and peroneus (fibularis) tertius.
Anatomy[edit | edit source]
Origin[edit | edit source]
Most of extensor digitorum longus arises from the anterior surface of the fibula, the upper part of anterior surface of the interosseus membrane, and the lateral tibial condyle.[2]
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. [2][3]
Nerve[edit | edit source]
Deep peroneal nerve, a branch of the common peroneal nerve.(L4, L5)[2]
Artery[edit | edit source]
Function[edit | edit source]
Extends lateral four digits and dorsiflexes the ankle.
Extensor digitorum 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.
