Heterotopic ossification of the Achilles tendon: case report

Abstract

The heterotopic ossification of the Achilles tendon is a rare condition that is characterized by bone formation within the tendon. It affects primarily male patients and is often associated with previous trauma or surgical intervention. We report a case of extensive heterotopic ossification of the Achilles tendon associated with plantar fasciitis and discuss its possible etiologic factors, clinical and radiologic features, symptoms, treatment options and its possible consequences for the function of the ankle and foot.
