Origin[edit | edit source]
Extensor Digitorum Brevis is one of the intrinsic muscles on the dorsum of the foot. It arises from the upper and lateral surface of the calcaneous, the floor of tarsal sinus, the talocalcaneal ligament, and the stem of the inferior extensor retinaculum [1][2]
Insertion[edit | edit source]
It inserts via tendons into the base of the proximal phalanx of the 1st toe, and the middle phalanx of the three medial digits joining with the extensor digitorum longus tendon (toes 2-4)[2][3]
Nerve Supply[edit | edit source]
Deep fibular nerve (S1, S2)[3]
Action[edit | edit source]
Assists Extensor digiorium longus in extending the metatarsophalangeal and interphalangeal joints of the 2nd, 3rd and 4th toes.[2] It also assists extensor hallucis longus and brevis in 1st toe metatarsophalangeal extension.
