Abstract
Maisonneuve fracture is a rare and complex ankle fracture characterized by a triad of injuries, including a medial malleolar fracture, injury to the inferior tibiofibular syndesmotic complex, and a proximal fibula fracture. This case report presents the case of a 53-year-old female who sustained a Maisonneuve fracture following a fall on the stairs. Physical examination revealed tenderness and swelling in the left ankle, and radiographs confirmed fractures of the medial and posterior malleolus of the left ankle. Despite receiving conservative treatment in the form of a plaster cast, the patient subsequently presented to the hospital with severe pain in the left ankle and proximal fibula. Further imaging examinations confirmed a Maisonneuve fracture accompanied by a proximal fibula fracture, medial malleolar fracture, and posterior malleolar fracture. The patient underwent successful open reduction and internal fixation of the left ankle. This clinical case underscores the significance of a thorough examination and imaging to precisely diagnose rare and complex fractures such as the Maisonneuve fracture, which may be overlooked in clinical practice. Therefore, clinicians should be vigilant of the potential for a Maisonneuve fracture in patients with ankle injuries to ensure timely and appropriate treatment.Key words: Maisonneuve fracture, tibiofibular syndesmotic complex, proximal fibular fracture, rare ankle fracture, clinical case.
