Extensor Hallucis Longus (EHL)

The Extensor Hallucis Longus (EHL) is a muscle located in the anterior (front) compartment of the lower leg. It plays a crucial role in the movement of the big toe and the dorsiflexion of the foot.

The EHL originates from the middle part of the fibula, which is one of the two long bones in the lower leg. It runs down the front of the leg and inserts into the base of the distal phalanx of the big toe. This muscle, along with other muscles in the anterior compartment, is responsible for lifting the toes and dorsiflexing the foot, which is the movement of bringing the top of the foot toward the shin.

Functionally, the EHL is particularly important in activities such as walking and running, where dorsiflexion is crucial during the swing phase of the gait. It is also involved in maintaining balance and stability during various lower limb movements.

Strengthening exercises that target the EHL include toe raises or resisted dorsiflexion exercises. Stretching exercises for the muscles in the anterior compartment can also contribute to maintaining flexibility and preventing issues related to muscle tightness.

In summary, the Extensor Hallucis Longus is an essential muscle in the lower leg, contributing to the dorsiflexion of the foot and the movement of the big toe. Understanding its role and incorporating appropriate exercises are important for promoting overall lower limb function and stability.
