Extensor digitorum longus muscle

Extensor digitorum longus muscle is a muscle located in the anterior compartment of the leg. It is responsible for extending the toes and dorsiflexing the ankle.

Anatomy

The extensor digitorum longus originates from the upper portion of the tibia, just below the knee. It runs down the front of the leg and inserts into the second to fifth toes. It shares its origin with the tibialis anterior and the extensor hallucis longus.

Function

The primary function of the extensor digitorum longus is to extend the four lesser toes. It also aids in the dorsiflexion of the ankle. This muscle plays a crucial role in activities such as walking, running, and jumping.

Clinical significance

Injury to the extensor digitorum longus can result in a loss of ability to extend the toes or dorsiflex the ankle. This can lead to difficulties in walking and balance. Treatment typically involves physical therapy, and in severe cases, surgery may be required.
