What happens to the ligaments and bones of an ankle in the case of a sprain?
A ligament is a band of solid fibrous tissue joining the bones between them. Concerning the ankle, we have a medial ligament joining the inferior tip of the tibia called medial malleolus and the medial aspect of the talus. This ligament is very solid and exceptionally impaired. The lateral ligament of the ankle presents 3 parts. Two of them join the tip of the fibula, called lateral malleolus to the lateral part of the talus and one joins the lateral malleolus and the lateral side of the calcaneus. For mechanical reasons, the different parts of the lateral ligament are permanently stressed during gait and exercise and are more prone to traumatic lesions. In an ankle sprain, the probability of a ligament rupture of any degree is maximal at the lateral side. In the case of an ankle twist the lateral ligament can be stretched, partially or completely ruptured. Then the ankle becomes painful and swollen and it is difficult for the patient to walk on the impaired limb. At that stage, it is
