Posterior approaches in malleolar fracture: When, why and how

The treatment of posterior malleolus fractures has radically changed over the last few years, therefore this study aims to summarize the current evidence on the usefulness of posterior approaches in the management of malleolar fractures. The main elements that suggest the use of a posterior approach to the ankle are: the posterior malleolus fragment shape and size; the presence of loose bodies at the fracture site; the possibility to obtain an anatomic fixation of the fracture; the presence of a posterior ankle subluxation; the eventually osteochondral impaction of the tibial plafond and the mechanical stability of the joint (9). The postero-lateral approach has been widely used to treat these fractures, but the posteromedial approach should be considered in specific cases. The anatomic reduction of these fractures leads to joint stability, with a consequent lesser occurrence of post-traumatic arthritis and better functional outcomes.
