4, tendon injuries The human body is distributed with many muscles, according to the organizational structure and different roles are divided into three kinds, including the formation of human movement is the skeletal muscle, by the tendon attached to more than two bones, by the contraction of the muscle to form a variety of human action. Tendon injuries are often caused by falls and collisions. They occur around the joints where they hit the ground. Localized swelling, pain, limited joint movement, but no pressure pain on the bones above and below this joint. Treatment: If there is no skin breakage, you can wet a towel with cold water or put a cold water bag on the injured area to apply cold compresses, which can make the blood vessels of the injured area contract and reduce bleeding. Cold compresses should be stopped after 1 hour or so. 24 hours later, if the local area is still red, swollen and painful, hot compresses can be used instead, with the purpose of expanding blood vessels to accelerate blood circulation and promote recovery. You can also use Chinese patent medicines such as Qixi San to invigorate blood circulation and remove blood stasis, and apply them to the injured area after mixing with water. If the pain is serious, or other abnormalities should be promptly go to the hospital for examination and treatment. 5. Bone injuries Serious fall and serious collision can cause bone injuries. Serious collision mostly causes bone splitting, and falls can cause bone fracture. Fractures can be divided into closed fractures and open fractures. Simple bone broken skin and muscle end of the broken, for closed fracture, bone broken at the same time there are skin and muscle broken, broken bones are exposed, known as open fracture. There are also comminuted fractures, where the bone is broken in multiple places. No matter which kind of bone injury, there are local symptoms such as swelling, pain, inability to hold weight, inability to move. Treatment: If there is a lot of bleeding, stop the bleeding first and then bandage and immobilize it to send it to the hospital. Bleeding can be stopped by bandaging to stop bleeding, using wider cloth straps, such as backpack straps, long towels or long strips of cloth, etc., tied above the injury. For example, a thigh fracture can be tied at the base of the thigh. However, it should be relaxed every 3-5 minutes to prevent necrosis of the tissues underneath the ligature due to ischemia as blood circulation stops for too long. At the same time to use a piece of wood, bamboo or cardboard, etc., placed under the fractured limb, the length of which should be more than the affected area of the upper and lower joints, with a bandage or a small sheet, such as bandage fixed. The bandage should not be too tight or too loose. The purpose of immobilization is to avoid the movement of the affected limb when transporting to the hospital, which may aggravate the wear and tear of the fracture. Then quickly send to the hospital for treatment.
