Most patients with ankle ligament rupture have a history of acute trauma, such as an acute sprain or contusion. In the case of ankle ligament rupture, firstly, the patient will have pain in the ankle joint with pins and needles pain. Secondly, there will be localized swelling of the ankle joint, with subcutaneous bruising and obvious pressure pain. In severe cases, there will be inversion or valgus deformity in the appearance, and the functional activity of the ankle joint will be limited. At this time, an MRI film of the foot or an ultrasound examination can be taken to make a definite judgment, and the degree of ankle ligament rupture can be determined. If the ligament is partially ruptured, conservative treatment can be given by fixing it in a plaster or brace, and applying a plaster to the injured area to activate blood circulation and eliminate blood stasis, reduce swelling and pain. If there is a complete rupture of the ankle ligament, surgical treatment is required, and an incisional ligament repair is performed under epidural anesthesia.
