Ankle Fractures and Pott Fracture

A 42-year-old male labourer from Delhi presents to the emergency department with severe pain and swelling over the right ankle following a fall from scaffolding 4 hours ago. On examination, the ankle is markedly swollen with ecchymosis. The foot is externally rotated and slightly abducted. Plain radiographs show fractures of the medial malleolus, lateral malleolus, and posterior tibial margin. What is the most likely diagnosis?

A 38-year-old female from Mumbai slipped on a wet floor and twisted her right ankle inward. She presents with moderate pain and swelling localized to the lateral ankle. On examination, the ankle is stable with no gross deformity. Plain radiographs show a fracture of the fibula 6 cm proximal to the ankle joint with an intact medial malleolus and no posterior malleolar involvement. There is widening of the medial ankle space on the mortise view. What is the most appropriate diagnosis?
