There are two peroneal tendons that run along the outer side of the ankle. One of the peroneal tendons inserts into the base of the fifth metatarsal on the outside of the foot (peroneus brevis); the other travels across the bottom of the foot and inserts into the base of the first metatarsal on the inner side of the foot (peroneus longus).
Peroneal tendonitis is inflammation of one or both of the peroneal tendons, caused by overuse or injury. More severe trauma can cause the peroneal tendons to become subluxed (moving out of normal position), partially torn, or even ruptured. We can determine the extent of the injury and recommend appropriate treatment options.
