What are the Peroneal tendons?

Peroneus longus and brevis are the two tendons that wrap around the outside of the ankle. They are easily felt just behind the bone on the outside of the ankle (fibula). They are important in everting the foot and have some control over the movements of the big toe.

What conditions can occur with these tendons?

The commonest abnormalities that can occur to these tendons are poor function, inflammation, tears, rupture or displacement.

What are the symptoms of Peroneal Tendon Disorders?

Poor function is usually due to genetic conditions such as Charcot Marie Tooth disease. These diseases result in weakness in the muscle of these tendons. This weakness results in high arched deformity of the foot due to an imbalance in muscle power around the ankle.

Inflammation of the tendons can occur due to inflammatory medical conditions or excessive strain on the tendons. The result is pain and swelling along the course of the tendons and this can be associated with swelling.

Tears, ruptures or displacement is normally the result of acute trauma and usually follows a severe ankle injury. Pain, swelling and lack of function are the commonest symptoms.

How are Peroneal Tendon Disorders diagnosed?

Clinical examination by a foot and ankle specialist is the key to an accurate diagnosis. Ultrasound scans and MRI can be very helpful in confirming the diagnosis and helping to plan rehabilitation.

What are my options for treatment?

Tendon dysfunction normally presents after a gradual onset so treatment is dependent on the overall functional demands of the individual. This may include surgery. Inflammation of the tendons will often respond well to rest and rehabilitation with a physiotherapist. The use of splints or a walking boot may be required. Tears, ruptures and displacements usually require surgery in active individuals. Expectant treatment in patients with lower demands may be an option.
