What is the insertion point for the extensor digitorum longus?

The extensor digitorum longus is a muscle in the anterior compartment of the leg, and its primary function is to extend the toes and assist in dorsiflexion of the foot. Its insertion point is at the bases of the distal and middle phalanges of the lateral four toes. This anatomical structure allows the muscle to effectively extend these toes during activities such as walking or running.

The specific attachment to the distal and middle phalanges enables the extensor digitorum longus to exert force when extending the toes, thus playing a crucial role in the movement of the foot. The muscle sends four tendons that separate and attach to these phalanges, allowing for coordinated and controlled toe extension.

Additionally, this anatomical knowledge highlights the significance of understanding muscular attachments and functions in sports therapy and rehabilitation, guiding practices in sports massage to alleviate any issues related to foot mobility and lower limb activity.
