颈椎管狭窄(Stenosis - Cervical)

椎管狭窄是椎管变细压迫脊髓或神经的一类疾病。它会引起疼痛、无力和/或麻木。当颈椎发生这种情况时,就称为颈椎管狭窄。

Introduction(概述)

  Spinal stenosis is a condition that causes a narrowing of the spinal canal, which can compress the spinal cord or nerves, resulting in pain, weakness, and/or numbness. When this condition occurs in the neck region it is referred to as cervical stenosis.

Symptoms(症状)

  A narrowing of the spinal canal typically doesn’t cause symptoms unless it progresses to a point where it significantly compresses the spinal cord or nerves. When this happens, intermittent or chronic pain, numbness, or weakness may be felt in the neck and shoulders and may extend down the arms to the hands. The neck pain is often described as stiffness, and people often complain of a numbness or heaviness in the arms and hands. When the spinal cord is compressed, there can be shock-like pain down the arms and legs, difficulty using the arms and hands, or difficulty walking.

  椎管狭窄通常不引起症状,除非进展到显著压迫脊髓或神经那一刻。这时,病人感到颈部或肩部间歇性或慢性疼痛、麻木或乏力,并可能向胳膊和手部放射。颈痛往往伴有僵硬,病人常抱怨胳膊和手部的麻木和沉重感。当脊髓受压时,会有触电样疼痛向胳膊和腿部放射,胳膊和手活动困难,或行走困难。

Causes(病因)

  Cervical stenosis is most frequently caused by degenerative changes (osteoarthritis) in the neck. After years of normal wear and tear, cushioning between bones in the spine may break down, allowing bones to wear against each other. At these sites, the body produces growths called bone spurs that may narrow the spinal canal, causing pressure on the spinal cord and nerves. Occasionally, large disc herniations and spinal tumors can narrow the spinal canal enough to compress the spinal cord.

  颈椎管狭窄往往由颈椎退行性改变(骨关节炎)引起。经过长年累月的磨损撕裂,脊柱骨头间的软垫破坏,使骨与骨之间相互摩擦。在这些部位,人体会长出骨赘,使椎管变累,导致脊髓和神经受压。有时,巨大的椎间盘疝出和脊柱肿瘤会使椎管狭窄足以压迫脊髓。

Summary(总结)

  Cervical stenosis may or may not require treatment depending on whether symptoms include pain or disability. Non-surgical treatments may include modifying activities toreduce stress on the spine, physical therapy, medications or injections toreduce pain and inflammation, or wearing a brace. In severe cases or those that are progressively worsening, surgery may be performed to correct the condition.

  颈椎管狭窄是否需要治疗取决于症状是否包括疼痛或功能障碍。非手术治疗包括调整活动方式以降低脊柱应力;物理治疗,药物或注射以减轻疼痛和炎症,以及使用支具。在严重病例,或进行性加重者,可能需要手术来矫正椎管狭窄。
