Abstract
Maisonneuve lesion is a rare entity, accounting for 7% of all ankle fractures. One of its variants includes a proximal tibiofibular dislocation, which is an even more unusual injury. This article reports the case of a 34-year-old male patient admitted to the emergency room with left lower limb edema after a sports trauma. A knee X-ray revealed an anterolateral subluxation of the proximal tibiofibular joint, with no signs of fracture. After limb evaluation, the diagnosis of Maisonneuve variant lesion with proximal tibiofibular dislocation was confirmed. The authors describe this case, addressing the clinical, radiological and surgical features of such variant.Entities:
