It is common knowledge that a broken bone and limited mobility is a fracture. However, there are some fractures are very hidden, sometimes the bones break, the appearance may not be different, and can barely move, but miss the best treatment period, eventually making the fracture place slowly separate, or even cause complete dislocation, at this time will bring great difficulties to treatment, or even cause lifelong disability. In fact, sprains and fractures can appear red and swollen, but the degree is not the same, such as ordinary sprains, often just capillary rupture, the degree of redness and swelling is not large, while the fracture is much greater than the degree of redness and swelling than sprains, usually manifested as a bun fermentation red and swollen. So if the foot is seriously red and swollen, even if there is no serious pain, a fracture may have occurred, and you need to seek medical attention as soon as possible. Wrong practice: the occurrence of sprains, slips and falls, resulting in soft tissue, muscle, ligament and other injuries or fractures, many users of the first time often take their own such as safflower oil, hot compresses, kneading and other means to activate blood and remove blood stasis, but do not know that this will further aggravate the injury. The correct approach: immediately stop the activity, reduce weight bearing, 24 hours with cold water rinse or ice cold compress injured parts to stop bleeding, timely medical attention, do not apply their own oil, improper rubbing, easy to cause fracture displacement, local injury nerve redness and swelling more powerful, delaying the best treatment time. Prevent fractures from the following aspects: practice to strengthen the body: more exercise to make the calcium in the blood more memory in the bones, improve bone hardness and prevent fractures. Adhere to exercise, increase outdoor activities, breathe fresh air, promote blood circulation and metabolism (such as: walking, jogging, tai chi, health exercises and other items); more sunshine: sunlight can promote the synthesis of vitamin D, and calcium metabolism depends on the role of vitamin D; ultraviolet rays in the sun can promote the formation and absorption of calcium in the body, maintain normal calcium and phosphorus metabolism, so that calcium in the bones increase bone hardness; before the disease Prevent first: the elderly should not go to places with many people and cars, and avoid going out in the rain and snow. Do not climb ladders or high activities, and do not walk on steep slopes, because the elderly are weak in the lower limbs and slow to respond to falls. If you have symptoms such as blurred vision, deafness or dizziness, you should go out as little as possible. When going to the toilet at night, sit on the bed for a while so that the leg muscles are in an excited state to prevent hypotension when the position changes. Prepare a stool for bathing, it is better to sit and put on clothes and shoes to prevent falls. Diet regulation: Eating more vegetables, protein and vitamin-rich food can prevent osteoporosis.
