Work-Related Cervical or Neck Injury usually results in either mechanical or radicular pain.
Workers mechanical neck pain is caused by wear and tear on the parts of the neck, often from job duties over time. It is similar in nature to a machine that begins to wear out. Mechanical pain usually starts from degenerative changes in the disc. As the disc starts to collapse, the space between the vertebrae narrows, and the facet joints may become inflamed. The pain is usually chronic. (Chronic pain builds over time and is long-lasting.) The pain is typically felt in the neck, but it may spread from the neck into the upper back or to the outside of the shoulder. Mechanical neck pain usually doesn't cause weakness or numbness in the arm or hand, because the problem is not from pressure on the spinal nerves.
Radiculopathy pain (Pinched Nerve) is from pressure or irritation in the nerves of the cervical spine can affect the nerves' electrical signals. The pressure or irritation can be felt as numbness on the skin, weakness in the muscles, or pain along the path of the nerve. Most people think of these symptoms as indications of a pinched nerve. Health care providers call this condition cervical radiculopathy.
Radiculopathy can be from job duties over time or from a single accident. The most common are degeneration, disc herniation, and spinal instability.
Degeneration: As the spine ages, several changes occur in the bones and soft tissues. The disc loses its water content and begins to collapse, causing the space between the vertebrae to narrow. The added pressure may irritate and inflame the facet joints, causing them to become enlarged. When this happens, the enlarged joints can press against the nerves going to the arm as they squeeze through the neural foramina. Degeneration can also cause bone spurs to develop. Bone spurs may put pressure on nerves and produce symptoms of cervical radiculopathy.
Spinal instability means there is extra movement among the bones of the spine. Instability in the cervical spine can develop if the supporting ligaments have been stretched or torn from a severe injury to the head or neck. People with diseases that loosen their connective tissue may also have spinal instability. Spinal instability also includes conditions in which a vertebral body slips over the one just below it. When the vertebral body slips too far forward, the condition is called spondylolisthesis. Whatever the cause, extra movement in the spine can irritate or put pressure on the nerves of the neck, causing symptoms.
