What type of fracture involves both the fibula and tibia at the ankle joint?

The type of fracture that involves both the fibula and tibia at the ankle joint is indeed Pott's fracture. This fracture is typically characterized by a severe injury to the ankle that results from excessive external rotation or lateral forces, causing a fracture of the fibula along with a fracture or dislocation at the distal tibiofibular joint. Pott's fracture is particularly important to recognize due to its implications for stability and potential complications in the ankle area, often requiring surgical intervention to ensure proper alignment and healing.

Other fractures mentioned have different anatomical focuses or mechanisms. For instance, Bennett's fracture involves the base of the first metacarpal in the hand, commonly due to a fist striking a hard object. Colles' fracture refers to a fracture of the distal radius in the forearm, typically occurring from a fall on an outstretched hand. Similarly, the Galeazzi fracture entails a fracture of the distal radius with associated dislocation of the distal radioulnar joint, which is also unrelated to the ankle. Therefore, Pott's fracture specifically pertains to the injuries involving both the fibula and tibia at the ankle joint.
