A fracture is a partial or complete break in a bone. A fracture can range from a simple break, which may not stop you from walking, to severe fractures, which may force you not to put weight on the ankle for a prescribed time period. Ankle fractures are common injuries and or caused by the ankle rolling inward or outward. Many people mistake an ankle fracture for an ankle sprain, but they are quite different. Any crack, break, or chip in the ankle bone (s) is considered a fractured ankle, while a sprained ankle is an injury where there is tear or disruption of the ligaments which ultimately can result in reoccurrence of sprains or dislocations if left untreated.
