A fracture is a partial or complete break of a bone. Fractures in the ankle can range from the less-serious avulsion injuries (small pieces of bone that have been pulled off) to severe shattering-type breaks of the tibia, fibula or both.
Ankle fractures are common injuries most often caused by the ankle rolling inward or outward. Many people mistake an ankle fracture for an ankle sprain, but they are quite different and, therefore, require an accurate and early diagnosis. They sometimes occur simultaneously.
