The Peroneus Longus and Brevus tendons are 2 major tendons that connect the peroneal muscles of the leg to bones in the foot. These tendons run along the outside of the leg and ankle. They function to help the ankle and foot turn out. Tendinitis is inflammation of the tendon where it inserts on the bone. Inflammation of the peroneal tendons (also known as peroneal tendinitis) most often occurs with overuse or repetitive activity. People who have “high-arched” feet or chronically roll their ankles are most susceptible to peroneal tendinitis. People with peroneal tendonitis might have pain and swelling behind the lateral ankle bone (fibula) or on the outside of the foot. Over time, chronic or untreated peroneal tendinitis can cause thickening of the tendon (tendinosis) or interstitial tearing of the tendons, which makes the tendon flat and wide.
Luckily, peroneal tendonitis responds very well to conservative treatment including rest, ice, strappings, oral anti-inflammatories and if severe enough, immobilization in a CAM walker boot. Patients may also benefit from a course of physical therapy. After the acute condition is resolved, balancing out the foot with the appropriate shoe gear and the addition of a custom or pre-fabricated orthotic usually prevents a reoccurrence. Only on rare occasions will surgical intervention be necessary to treat this condition.
