If the patient has the symptom of clicking after twisting the foot, it may be due to the occurrence of ligament damage, avulsion fracture, or even joint dislocation. At this time, the patient can first take some emergency temporary treatment, such as braking and immobilization, cold compresses, topical medication and so on. After that, patients should ask others to help them to go to orthopedic department for further treatment as soon as possible. Specific treatment measures are as follows: 1. Braking and immobilization: after the patient has this symptom, do not try to continue to move the ankle joint, and do not continue to go down to the ground to bear weight. The patient should sit down quickly, remove shoes and socks, and use an ankle brace to temporarily immobilize the affected area. If an ankle brace is not available, a bandage can also be used to immobilize the affected area. 2. Cold compress: For the symptomatic area, use ice to apply cold compress for 5~10 minutes as soon as possible to relieve localized internal bleeding. 3. Topical medication: If the patient has topical medication for bruises at home, such as Yunnan Baiyao spray, it can be used temporarily on the affected area, but do not rub it. 4. Further treatment: The patient should go to the hospital in time, and the location and severity of the injury can be clarified through X-ray film, MRI and other examinations. If it is confirmed that there are more serious lesions mentioned above, surgery may be required. For example, in the case of avulsion fracture, the fracture may need to be surgically repositioned and internally fixed with Kirschner pins.
