In life, there are always some accidents. And ankle sprain is one of the more common of these accidents, especially for women who like to wear high heels, a little inattention is easy to ankle sprain. Ankle sprain, we will find a problem, is a slow recovery, and even twisted once after the back is often sprained, so patients dare not wear high-heeled shoes, do not dare to walk on uneven surfaces, and even in the dark can not see the road when walking to be careful. What is the reason for this? First, the special injury site, the most common ankle sprain in the lateral ankle, also called inversion type sprain. The main structures associated with the lateral aspect of the ankle are the lateral ankle (distal fibula), the talofibular ligament, the calcaneofibular ligament, and the talus. A mild lateral ankle sprain is only an injury to the ligaments, while a severe ankle sprain can result in a fracture of the lateral ankle or even a fracture-dislocation of the ankle. Usually this kind of serious injury is not common, the most common is the talofibular ligament injury. Second, the degree of injury, talofibular ligament injury is divided into three degrees according to the degree of tear, one degree is just a microscopic tear, pain is very light, basically no swelling, rest a few days will be fine. The second degree is a partial tear of the ligament, the ankle has obvious swelling and pain, 72 hours after the injury, such as cold compresses, and then plaster and other methods of braking, usually 20 days to a month or so can also be healed. The most serious is a third-degree tear, that is, the ligament is completely ruptured, the patient’s ankle will appear a large ecchymosis, swelling and pain are very serious. If not treated correctly, although about a month can walk, leaving the pain and dysfunction, will continue for a long time, but also gradually aggravate, seriously affecting the normal life. Third, the specificity of the injury site, a simple sprain of the outer ankle, or a rupture of the talofibular ligament, may cause cartilage wear of the talus and tibial joint surface, bone spurs in the anterior and posterior internal and external ankle bones, and the talus inversion of internal rotation, which is the main cause of the slow healing of the ankle after sprain. Fourth, improper treatment after injury, ankle sprain after ignoring the treatment work, or treatment work measures are not appropriate, so the problems left behind, and even some are caused by irreversible damage. This will affect the subsequent recovery. Therefore twisted ankle people, must take the first ankle sprain seriously, the cast on the cast, the ligament surgery on the surgery, because once the occurrence of traumatic arthritis, then need to consider doing ankle replacement or fusion.
