颈椎后方有关节突关节，其表面有关节软骨，周围包绕关节囊，其内充满滑液。正常上下颈椎间有椎间关节 、钩椎关节、关节突关节等相关连。随着年龄增大，颈椎发生退变，椎间盘变性、突出，椎间隙高度下降，关节突关节软骨面磨损，可导致颈部僵硬疼痛等不适，同时出现骨刺，有时可压迫脊髓及神经根，引起相应症状。  警告：请在有WIFI的场所观看视频，土豪请随意。
Cervical Facet Osteoarthritis 颈椎小关节骨关节炎 Cervical facet osteoarthritis, sometimes called cervical facet joint syndrome, is a degenerative condition that causes pain and stiffness in the cervical, or neck, region of the spine. 颈椎小关节骨关节炎，有时又称为颈椎小关节综合征，是引起颈椎即脊柱颈段的疼痛和僵硬的一种退变性疾病。 The cervical spine includes the top seven levels of the spine, labeled C1 through C7. 颈椎包括脊柱的最上面7节，称为颈1到颈7。 There are two facet joints on either side of the back of each vertebra in the neck. These joints provide stability, while also enabling neck movements such as turning or nodding the head. 每个颈椎后方每侧都有两个关节突关节，它们有助于颈椎的稳定，同时也有利于颈部转动和点头等活动。 Cartilage lines each facet joint in the neck, and this cartilage is surrounded by a capsule filled with synovial fluid. 颈椎小关节表面都有关节软骨，并有充满滑液的关节囊包绕。 This synovial fluid helps lubricate the facet joint, enabling smooth movements of the joint complex. 滑液可润滑小关节，有利于关节平滑地进行复杂的活动。 In cervical facet osteoarthritis, this cartilage begins to degenerate, or break down. 在颈椎小关节骨关节炎，这些关节软骨开始退变破坏。 The cartilage begins to thin and may even disappear completely, causing bone-on-bone friction of the facet joints in the neck. 关节软骨开始变薄甚至完全消失，导致颈部小关节骨与骨的摩擦。 This friction can lead to the development of osteophytes, or bone spurs. 这样摩擦会导致骨赘或骨刺的发生。 If these osteophytes impinge on any cervical nerve roots, pain, weakness, or tingling may radiate along the path of the nerve into the arm and hand. 如果骨刺挤压颈神经根，会引起沿着神经走行放射的疼痛、无力或麻木，一直到臂和手。 Cervical facet osteoarthritis may cause pain in the neck and upper back as well as the shoulders and between the shoulder blades. 颈椎小关节骨关节炎会引起颈部和背部以及肩部、肩胛骨之间的疼痛。 It may also cause headaches, a form of radiated or referred pain, especially in the back of the head. 它还会引起头痛，尤其在头的后部，这是一种放射痛或牵涉痛。 Patients with cervical osteoarthritis will often have tenderness or swelling over the site of the affected facet joints, as well as reduced range of motion in the neck. 患有颈椎骨关节炎的患者常常有受累小关节部位的压痛和肿胀，以及颈部活动的减小。 （高晨珉 转） |
