title: Unrecognized fracture of the posteromedial process of the talus--a case report and review of literature.
abstract: In this report, we present a rare case of an initially unrecognized fracture of the posteromedial process of the talus sustained in a seldom reported position of dorsiflexion and supination of the foot. Fractures of the posteromedial process of the talus are very rare and represent an important diagnostic problem. Difficult x-ray visualization makes these fractures often misdiagnosed as ankle sprains. Complications due to this kind of fractures can include serious consequences such as avascular osteonecrosis, tarsal tunnel syndrome, post-traumatic osteoarthritis, or chronic pain. Timely diagnosis represents an important factor in the development of these conditions. A heightened awareness in examining ankle traumas with specific patient history details is of great importance. The most common mechanism of injury includes dorsiflexion and pronation of the foot. However, in an increasing number of cases alternative mechanisms have been described, all including high-energy impacts. Our patient sustained a fracture of the posteromedial process of the talus in dorsiflexion and supination with high-energy impact due to a 3-m fall. The patient was treated with excision of the fragment six months after the injury, and 18 months after the surgery the patient returned to his normal daily activities with significantly less pain in the posteromedial part of the ankle.
