Take ankle ligament injury as an example: first of all, make a quick self-judgment, check the painful area for deformity, bleeding, feel for bone rubbing sensation, bone rubbing sound (the “click” feeling and sound of fracture block rubbing), the stability of the injury site is obviously destroyed, etc. Note: If any of the above conditions exist, it means that there is a possibility of fracture or an unstable ligament injury of more than 3°, you must immediately apply pressure bandage, brake, simple fixation, ice, and then go to the orthopedic department! Special note: If there is bleeding, it is not possible to do cold compresses; if you find an exposed bone, you must not rush to return it by yourself, otherwise it will increase the risk of osteomyelitis, and you must go to the hospital to be sterilized by a professional doctor before resetting the open fracture. For the vast majority of soft tissue contusions and ligament strains, bleeding and swelling within the soft tissue are likely to increase rapidly if early treatment is not performed quickly. Basic early treatment principles and methods are as follows: 1, immediate compression (early use of ankle brace or elastic bandage to limit swelling and protect tissue secondary injury); 2, immediate elevation (such as wrist, ankle injury, immediate elevation, can be above the level of the heart, conducive to swelling reduction and prevention of further swelling), at least do not let the injury site as usual low hanging; 3, cold compresses or ice (in tolerable (the temperature as much as possible to increase the time of cold compress, the role is to close the broken capillaries, reduce bleeding, edema, there is a certain pain relief) but ice only in the first 24 hours after the injury can be carried out. Myth: People often only pay attention to the front outer part of the foot and ankle where the pain is the most severe, and ignore the inner part where the injury is also present but the symptoms are still mild, and in some cases the symptoms on the inner part are not even noticed until a few days later. Therefore, icing the anterolateral side alone is sometimes not enough, except in cases where the injury is only minor on the lateral side. The right way: apply cold compresses all around the ankle joint, which is comprehensive. However, cold compresses should not be applied to the end parts like toes and fingers, otherwise frostbite will easily occur. Caution: diabetic patients, hypertensive patients who have developed vascular lesions in the lower limbs, do not do ice without understanding the situation, otherwise it may lead to gangrene or even amputation! 4, hot compresses (24 hours after the injury or a little later to start, temperature control at 50-60 ° C, half an hour each time, more than 2 times a day, more is better, can be insisted on for several days, weeks until the pain symptoms completely disappeared, the role is to facilitate the swelling subsided, improve local circulation, facilitate soft tissue healing), hot towels, hot water bags, hot water foot bath, infrared physiotherapy machine is a good choice; 5, early braking. Rest (the first few days after the injury, need adequate rest; premature and unreasonable activities will increase the time required for recovery); 6, functional exercises (according to the swelling of the tissue, recovery progress to do reasonable exercise, conducive to the early recovery of most of the functions). Good stability of the injury, 2-3 days you can do the following exercises. For poorly stable injuries, functional exercises should be started under the strict guidance of a physician, with the possibility, of course, of protecting the joints and ligaments with the help of more specialized braces. The length of the rehabilitation period varies from person to person, ranging from a few days to a few months. Some people need to overcome chronic pain under medical supervision in the later stages of rehabilitation. The vast majority of soft tissue injuries that are carefully managed and treated will return to satisfactory function.
