Trimalleolar fracture: The endless posterior malleolus fracture debate, to repair or not to repair?
Ankle fracture is one of the most common fractures presenting in the emergency department. The fracture varies from unimalleolar, bimalleolar or trimalleolar. Involvement of the posterior malleolus is common and ranges from small avulsions to large intraarticular fragments causing subluxation of the talus. If left untreated, the resulting step-off, comminution or posterior talar subluxation may lead to osteoarthritis and further disability. To date, no consensus exists regarding the management of posterior malleolus fractures in the set-up of trimalleolar fractures. In this review we provide an overview of the literature on the available treatment options for posterior malleolar fracture in the set-up of trimalleolar fractures.
