Peroneal Tendon Tears
Peroneal Tendon Tears Definition
The peroneal tendons are two tendons that run along the outer part of the ankle behind the fibula. Their main function is to evert, or turn the foot outward. Sometimes after an injury to the ankle, these tendons can become inflamed or even torn.
Peroneal Tendon Tears Symptoms and Anatomy
The peroneus brevis and peroneus longus glide in a groove posterior to the fibula and attach to the foot. The brevis attaches to the base of the 5th metatarsal while the longus curves underneath the foot to attach to the undersurface of the 1st metatarsal. A tear of these tendons can results in increased pain and swelling on the outside part of the ankle. Weakness with eversion is possible, but in many tears patients have good strength.
Peroneal Tendon Tears Treatment
Peroneal tendon tears are initially treated with conservative measures including rest, brace vs boot, anti-inflammatories and ice. Sometimes physical therapy is necessary if these initial treatments are not effective. If symptoms persist, MRI can be performed to show the extent of the injury to these tendons and the rest of the ankle. Surgery is reserved for patients that have failed all other conservative treatments.
Peroneal Tendon Tears Surgery
The goals of surgery are to provide pain relief and improve the function of the peroneal tendons. This is accomplished via a variety of different methods, depending on the severity of the injury. Your surgeon will discuss with you all surgical options during consultation.
