Peroneal Tendon

The peroneals are a set of two tendons that are on the lateral aspect of the leg.The peroneal tendons have two modes of action. They are the main adductors of the foot and provide weak plantarflexion of the foot. The peroneus longus main function is to stabilize the first ray by providing plantar flexory force. The previs tendon which attaches to the base of the 5th metatarsal helps to abduct the foot. Together these further help stabilize the ankle to prevent ankle sprains.
