Ankle sprain is the most common disease in trauma orthopedic clinic, and is called one of the “three giants of the clinic”, so how to treat ankle sprain? The ankle joint is composed of the distal tibiofibula and talus. Most of them are caused by jumping up and stepping on the ankle, or tripping over the ankle, resulting in inversion or valgus of the ankle joint, which is commonly known as “bending the wood”. The ankle joint is more prone to inversion sprain because of the long ankle point of the outer ankle fibula and the shallow ankle point of the short inner ankle tibia, and injuries to the outer ankle ligaments including the anterior talofibular ligament and the heel fibular ligament are more common. Ankle sprains are mainly injuries to the surrounding ligaments, and if the injury is severe, ankle fractures occur. What are the manifestations of ankle sprain: The clinical manifestations are mainly obvious history of injury, swelling of the foot and ankle, pain, local pressure, petechiae, painful ankle joint activities, sometimes the injury does not feel very painful, continue to move, and when the activity stops, that is, the pain is obvious. Patients with chronic injuries or repeated sprains have relatively mild symptoms, usually walk unsteadily or are prone to injury, and drawer test and inversion stress test can elicit positive signs. How to deal with ankle sprain: 1. After the occurrence of ankle sprain should be immediately to the hospital for emergency treatment, in the case of conditions before the consultation can be handled according to the principles of RICE, RICE principles include rest rest, a closer understanding is to eliminate weight bearing, ice ice, compression compression bandage, elevation elevation of the affected limb. (I do not recommend to go to the bruise doctor in the acute stage of the so-called reset, compression or knocking, because it will aggravate the injury), the doctor will assess the injury after the consultation to decide the treatment plan. 2. First of all, orthogonal and lateral X-rays of the ankle should be taken to rule out any ankle fracture. If necessary, MRI can be performed to determine the ligament damage. 3. At the time of consultation, the injury will be evaluated to determine the treatment plan. Braking, elevation of the affected limb, continued icing (icing means applying an ice pack to the painful and swollen part of the injury, with a thin towel in between), and external fixation with a brace or cast if necessary, will be required. The affected limb should not be able to walk with weight. For a simple soft tissue injury, the affected limb should rest for about two weeks. After that, pay attention to protection and wear ankle brace when moving around. 4.After the acute period, about 3 days later, you can consider local physical therapy or hot compress. 5.Anti-inflammatory and pain-relieving drugs should be applied (Fasthone ointment and Ciloxel anti-inflammatory and pain-relieving drugs are more commonly used in our department). 6. Surgery is needed for combined fractures and dislocation. In the chronic phase, the ankle joint is unstable and repeatedly sprained, surgery is needed to repair the ligaments.
