Where does the fibularis brevis muscle insert?

The fibularis brevis muscle, also known as the peroneus brevis, is an important muscle located on the lateral side of the lower leg. Its primary function is to evert the foot and assist in plantar flexion. The correct insertion point for the fibularis brevis is the lateral tubercle at the base of the 5th metatarsal. This insertion allows the muscle to effectively stabilize the foot and maintain its position during various activities, particularly those involving lateral movement.

The specific location at the base of the 5th metatarsal is significant, as it is strategically placed to contribute to foot function and maintain balance during walking and running. The attachments of the fibularis brevis muscle play a crucial role in overall foot mechanics, especially in movements that require the foot to roll outward. Understanding these anatomical details is vital for sports massage practitioners, as it enables them to address issues related to muscle imbalances, strains, and injuries in active individuals.
