In addition, an x-ray or other advanced imaging studies may be needed to fully evaluate the injury. To diagnose a peroneal tendon injury, the surgeon will examine the foot and look for pain, instability, swelling, warmth and weakness on the outer side of the ankle. Diagnosis of Peroneal Tendon Injuriesīecause peroneal tendon injuries are sometimes misdiagnosed and may worsen without proper treatment, prompt evaluation by a foot and ankle surgeon is advised. Therefore, if you feel the characteristic snapping, see a foot and ankle surgeon immediately. Sporadic pain behind the outside ankle boneĮarly treatment of a subluxation is critical since a tendon that continues to sublux (move out of position) is more likely to tear or rupture.A snapping feeling of the tendon around the ankle bone.Damage or injury to the tissues that stabilize the tendons (retinaculum) can lead to chronic tendon subluxation. In other cases, subluxation occurs following trauma, such as an ankle sprain. In some cases, subluxation is due to a condition in which a person is born with a variation in the shape of the bone or muscle. Subluxation means one or both tendons have slipped out of their normal position. Sporadic pain (occurring from time to time) on the outside of the ankle.The symptoms of degenerative tears may include:
Having high arches also puts you at risk for developing a degenerative tear. In degenerative tears, the tendon is like taffy that has been overstretched until it becomes thin and eventually frays. Weakness or instability of the foot and ankleĪs time goes on, these tears may lead to a change in the shape of the foot in which the arch may become higher.ĭegenerative tears (tendonosis) are usually due to overuse and occur over long periods of time, often years.Immediate symptoms of acute tears include: Symptoms of tendonitis include:Īcute tears are caused by repetitive activity or trauma. The inflammation is caused by activities involving repetitive use of the tendon, overuse of the tendon or trauma (such as an ankle sprain). Tendonitis is an inflammation of one or both tendons. Basic types of peroneal tendon injuries are tendonitis, tears and subluxation. In addition, people with higher arches are at risk for developing peroneal tendon injuries. They most commonly occur in individuals who participate in sports that involve repetitive ankle motion. Peroneal tendon injuries may be acute (occurring suddenly) or chronic (developing over a period of time). Causes & Symptoms of Peroneal Tendon Injuries The main function of the peroneal tendons is to stabilize the foot and ankle and protect them from sprains. One peroneal tendon attaches to the outer part of the midfoot, while the other tendon runs under the foot and attaches near the inside of the arch.
The two peroneal tendons in the foot run side by side behind the outer ankle bone. A tendon is a band of tissue that connects a muscle to a bone. To understan peroneal tendon injuries, it's important to first understand what the peroneal tendons do. Peroneal Tendon Injuries What Are the Peroneal Tendons?
