扭伤是孩子较为常见的运动损伤之一。踝关节、腕关节和膝关节是扭伤的多发部位。扭伤是关节周围连接不同骨骼的韧带受到拉伸、挤压而造成的损伤。扭伤后,关节部会出现肿胀、疼痛等,使运动能力受限。此外,由于扭伤时身体常因发生扭转而失去平衡,因此可能会与外物产生摩擦、碰撞等,造成擦伤、淤斑或出血等。 Spraying is one of the more common sports injuries in children. Ankles, wrists and knees are multiple sites of sprains. Sprains are injuries caused by stretching and crushing of the ligaments that connect different bones around the joint. Sprain, the joints will appear swelling, pain, etc., so that exercise capacity is limited. In addition, the body is often out of balance due to torsion when sprained, so it may cause friction, collisions and the like with foreign objects, resulting in abrasions, ecchymosis or bleeding.
