Large posterior malleolar fragments should be fixed in the context of complex ankle fractures. Although this is typically achieved using an open posterolateral approach to the ankle, our case illustrates a novel percutaneous technique for reducing the posterior malleolar fragment. A good reduction was achieved and the patient was satisfied with his clinical outcome. At 13 weeks follow-up, reduction was maintained and there was radiographic evidence of fracture union. In complex ankle fractures, the posterior malleolus can be satisfactorily reduced percutaneously without need for open reduction.
