Final answer:
A Bimalleolar fracture refers to an ankle injury that involves fractures to both the medial and lateral malleoli. A Pott's fracture usually includes the medial and can involve the lateral malleolus with dislocation, whereas a Trimalleolar fracture also includes the posterior malleolus.
Step-by-step explanation:
The term for an ankle fracture affecting both the medial and lateral malleoli is a Bimalleolar fracture. A Pott's fracture typically involves the medial malleolus and can extend to involve the lateral malleolus, often with dislocation. When the injury also includes the posterior malleolus of the tibia, it is known as a Trimalleolar fracture. Ankle fractures are serious injuries that can affect the stability and function of the talocrural joint, which is comprised of articulations between the talus bone and the two malleoli of the tibia and the fibula. Proper medical attention is crucial for an accurate diagnosis and appropriate treatment.
