Neck Strains and Sprains 颈部扭伤和拉伤 A neck strain or sprain occurs when one or more muscles, ligaments, or tendons in the neck are injured. 颈部扭伤或拉伤是颈部的一块或多块肌肉、韧带或肌腱的损伤。 The cervical spine has a wide range of motion in all directions. This motion is supported by a complex structure of muscles, ligaments, and tendons. 颈椎在各个方向上有很大范围的活动度，这是由肌肉、韧带、肌腱等复杂的结构来支持的。 The large neck muscles, such as the sternocleidomastoid and the trapezius, enable the gross motor movements in the neck. The large, triangle-shaped trapezius connects the back of the neck and the shoulders. 象胸锁乳突肌、斜方肌等颈部大的肌肉，是颈椎活动的主要动力。巨大的三角形的斜方肌，连接着颈后部和肩部。 A neck strain affects cervical muscles and tendons—bands of fibrous tissue that connect the muscles to bones. 颈部扭伤累及颈部肌肉和肌腱。肌腱是连接肌肉和骨的纤维组织束。 Sprains affect the ligaments—bands of fibrous tissue that connect the vertebral bones to each other and provide stability to joints. 拉伤累及韧带，它是将颈椎相互连接起来的纤维组织束，维系关节的稳定。 Neck strains and sprains occur when these soft tissues are stretched beyond their normal limits or torn, causing pain, tenderness, and difficulty moving the neck. 当颈部的这样软组织所受拉力超过它们正常的极限或发生撕裂，就发生颈部扭伤和拉伤，会引起疼痛，压痛和颈部活动困难。 Neck pain may radiate into the shoulder and over the shoulder blade and upper back when the trapezius muscle is strained. 颈部疼痛会放射到肩部，当斜方肌扭伤，可引起肩胛及背部的疼痛。 Neck strains and sprains can occur either due to a sudden injury, such as a car accident that forces the head suddenly forward and then backward in a whiplash motion. 急性的外伤，比如车祸使头部突然向前然后向后如同挥鞭样的活动，也会引起颈部扭伤或拉伤。 These injuries can also develop over time due to poor posture. 因为长时间姿势不良，也会逐渐产生这些损伤。 Muscle strain in the neck can also be accompanied by inflammation around the injured tissue, and neck muscle spasms as the body tries to stabilize the injury. These muscles spasms can be quite painful. 当受伤组织周围有炎症时，人体试图稳定受伤部位，使颈部肌肉痉挛，也会伴随出现颈部肌肉扭伤或拉伤。这些肌肉的痉挛会引起剧烈疼痛。 Many cases of neck strain or sprain will resolve after a few days, but flare-ups or aching pain may continue for weeks or months after the initial injury. 很多颈部扭伤或拉伤在一些日子后会恢复，但突发加重或酸痛可能持续到初始损伤后数周或数月后。 （高晨珉 转） |
