Peroneal Tendinitis

Brief Outline of Peroneal Tendinitis

The peroneal tendon is involved in stabilising the foot and providing support to the ankle to prevent lateral rolling of the joint. When the foot pronates it causes the tendon to stretch leading to pain and inflammation. The tendon has to work harder to stabilise the foot during pronation. Runners who have excessive pronation often develop this condition.

Anatomy and Physiology Peroneal Tendinitis

The tendons of peroneus longus and peroneus brevis run from the peroneal muscles to the foot. They pass around the lateral malleolus (the bony prominence on the outside of the ankle) and attach just behind the big toe. These tendons, along with the peroneal muscles, help to stabilise the foot and assist the calf muscles to extend the foot. When the foot pronates causing the tendons to stretch, it puts extra stress on the tendons, leading to pain and inflammation. Running and jumping cause repetitive flexing of the peroneal muscles and can lead to inflammation of the tendons, especially with excessive pronation.

Cause of Peroneal Tendinitis

Over-pronation of the foot during running or jumping. Prior ankle injury leading to an incorrect path of travel for the tendons.

Signs and Symptoms of Peroneal Tendinitis

Pain and tenderness along the tendons. Pain is most severe at the beginning of the activity and diminishes as the activity continues. Gradual increase in pain overtime.

Complication If Left Peroneal Tendinitis Unattended

Unattended tendinitis can lead to a complete rupture of the tendons. Peroneal tendinitis can lead to subluxations. The chronic inflammation can also lead to damage to the ligaments surrounding the tendons.

Our Treatment for Peroneal Tendinitis

Anti-inflammatory injection. Shockwave therapy.

Long-term Prognosis for Peroneal Tendinitis

With proper treatment, peroneal tendinitis will usually heal completely with no lingering effects. In rare cases, the tendinitis may not respond to traditional treatment and may require surgical intervention to relive the pressure causing the inflammation.
