Ankle fractures can be caused by various modes of trauma, e.g., twisting, impact, and crush injuries. Falling, tripping, or sports activities may cause twisting forces through the ankle. Impact injuries may result from falling from a height with impaction of the distal tibia and fibula against the talus.
You can expect most ankle fractures depending on how severe they are, to take 4-8 weeks for the bones to heal completely and up to several months to regain full use and range of motion of the joint. More severe fractures, especially those requiring surgical repair, may take longer to heal. https://google.com/
