The unit basketball game, Wang accidentally sprained his foot again, as usual, he put some bruising oil, but found that the next day the ankle joint is increasingly swollen, two weeks later still can not get off the ground. He was anxious and afraid, and came to the clinic with crutches, afraid that he was like Liu Xiang or Yao Ming, tendon or bone problems. For sports injuries and rehabilitation, the love of sports, but Wang almost know nothing. 1, usually walking and sports do cause the foot sprain is the same? How to initially determine its severity? How to deal with mild injuries? Whether walking, going up and down stairs or playing sports, foot sprains are the most common trauma we encounter. According to statistics, one in every 10,000 people in the United States will sprain their foot every day. Are the injuries caused by walking and exercising the same? For the same person, running and jumping is faster than walking, the impulse is greater, and the injury will be more severe; however, for different individuals, the injury caused by the same external force may vary greatly. An athlete and an old lady often inactive in the stairs when the foot twisted, the athlete may rest, a plaster on the activities as usual; the old lady may “hurt the bones”, bedridden for months but difficult to recover. If we sprain the foot in the case of speed, the foot is not swollen and not very painful, we may only soft tissue sprain, did not hurt the ligaments; and when we sprain the foot in running and jumping, the foot immediately swollen, pain can not stand and walk, then we may sprain the ligaments. The injury is more serious, you may have to go to the doctor. If the injury is mild, we can usually deal with the RICE principle: that is, rest (Rest), cold compresses (Ice), compression bandages (Compression), elevation of the affected limb (Elevation). Recovery is usually possible within two weeks, and young people recover more quickly, often running and jumping again after a day or two of rest. But during the recovery period, if the pain does not go away for a long time, can not go down, the damage must be more serious and should not be taken lightly. 2.How to find out whether the ligament is ruptured? How to deal with it at that time? When we sprain our foot, how do we know if the ligament is ruptured? If it is an acute injury, the doctor may give us an ultrasound or MR examination, which is a better non-invasive means for diagnosing ligament or soft tissue injury. In general, ultrasound is economical and quick and is more often used in outpatient settings. If we sprain our foot and do not receive timely treatment; after a period of time, the injury may not be very painful and we may be able to walk slowly; after a period of time, we may be able to run and jump, but we may feel our foot is weak when walking on uneven roads, and we may sprain once or twice a year. At this time, we often think that the injury has been healed, it is fine, no need to go to the doctor. Unbeknownst to us, this is often a secondary manifestation of a ligament injury – ankle instability. If left untreated, the ligaments and articular cartilage around the ankle joint will wear and degenerate more quickly. It’s like when the belt of a machine is loose and left untreated, the bearings and engine may also develop problems sooner. There are many different ways to diagnose chronic ankle instability, but the easy ones are physical examinations and X-rays. When we find that the affected foot is more likely to turn inward or be moved forward like a drawer (calf fixation) than the healthy foot, we may have torn the lateral ligaments of the ankle. Similarly, we can determine if the medial ligament is damaged. In acute ligament injuries, as with all acute sports injuries, the initial treatment principle is the RICE principle described above; after determining the severity of the injury, the patient’s occupation and requirements, rehabilitation conservative treatment or surgery can be performed respectively. In the case of chronic injury, we will have to go to the hospital to do the relevant examination and timely treatment after accurate diagnosis. 3.For ligament rupture, is it troublesome to treat? How to recover? Can I still play sports in the future? According to the severity of ligament injury, it can be divided into three degrees. Usually, injuries of degree I to II can be rehabilitated and improved. In the case of a degree III injury, surgery can be performed when systematic conservative treatment does not work. Ligaments and tendons are often referred to as “tendons and bones” in the tendons, if completely ruptured, surgical repair will take three months to fully recover. During these three months, the rehabilitation can be carried out in three stages: in the acute stage, the hemorrhage and swelling of the ankle joint is still continuing, at this time, it is treated according to the RICE principle; in the pre-rehabilitation stage, the hematoma is being mechanized, what is needed is to gradually make the ligaments firmly connected, and to gradually eliminate the swelling by orderly exercise under the premise of protecting the ligaments of equal length; in the rehabilitation stage, the ligaments have been connected by fibroblasts and are relatively firm, so active rehabilitation is needed. exercise. After one and a half months, we can often walk on the ground with the help of a brace or under the protection of a brace, and after three months we can return to a basic normal level of activity. For patients after a ligament injury, it is perfectly possible to play sports after rehabilitation. Such as Brazil’s Ronaldo, in the quadriceps tendon rupture, after surgery and rehabilitation exercises, and soon returned to the level of the world’s top athletes; but for athletes or enthusiasts who return to the field after ligament injury, before the game or sport, warm-up preparations must be adequate, the first exercise must be measured, not too fatigue. For example, Wang’s foot sprain was diagnosed by ultrasound and MR as a third degree injury to the lateral ankle ligament, and finally, surgery was taken to treat the injury, and he returned to normal sports level after three months.
