Medial malleolus injuries to the ankle result from eversion forces. Depending on the direction and strength, forces may result in sprain or rupture of the deltoid ligament or fracture of the medial malleolus. These fractures are usually treated operatively. Force directed obliquely may result in a bimalleolar fracture.
