Unstable walking in cervical spondylosis is caused by the compression of the spinal cord by cervical spondylosis, which leads to spinal cord-type cervical spondylosis. Due to the protruding discs, enlarged bone spurs or ossification of the posterior longitudinal ligament and hypertrophy of the ligamentum flavum, these factors compress the spinal cord, resulting in spinal cord compression, nerve damage in the lower limbs and unstable walking, often with a feeling of stepping on cotton or without a heel, and often unable to grasp a direction when walking, resulting in the phenomenon of deviation. When walking unsteadily with cervical spondylosis, we should have an early MRI to determine the spinal cord compression in cervical spondylosis. If the symptoms of unstable walking continue to worsen, then we should consider surgery because conservative treatment for cervical spondylosis is often ineffective and surgery is the only option. During conservative treatment, we should avoid neck injury to avoid transient tetraplegia after injury, which can have serious adverse consequences.
