An explanation of peroneal tendonitis. Written by Dr. Kolodenker, Sports Medicine and Surgery Podiatrist in Orange County.
There are two peroneal tendons, peroneus longus and peroneus brevis. They run side-by-side behind the outer ankle bone, fibula.
The Peroneus Brevis tendon attaches to the outer part of the mid-foot onto the base of the 5th metatarsal. During an inversion ankle injury this tendon can cause a fracture of the 5th metatarsal. This type of fracture occurs about 20% of the time with ankle sprains.
The Peroneus Longus tendon runs under the foot and attaches near the inside of the arch. It glides over the lateral aspect of the cuboid bone. The lateral foot is a common area for injuries for this tendon.
There are several treatment options.
Dr. Kolodenker is located in Irvine and Huntington Beach.
