The patient underwent osteosynthesis of both the ankles in the same sitting with malleolar screws with no significant complaints at 3 year follow up. Discussion: In the present case, the right side had a vertical medial malleolar fracture representing a supination-external rotation type injury while the left side had transverse fracture represented a pure abduction injury.
