Intermittent claudication of spinal origin is caused by compression of the spinal cord, mostly due to long-term compression of the spinal cord by degenerative disorders of the cervical or thoracic spine, resulting in impaired blood supply and hypoxia. When walking for a longer period of time, a sensation of tethering in the thorax, abdomen or lower extremities occurs, so that the patient cannot walk for a long period of time and needs to rest for a few minutes to improve the symptoms before continuing to walk. These patients have a positive cone bundle sign and usually walk with an unstable gait or a feeling of stepping on cotton on the soles of the feet, which is easily distinguished when thinking of this disease. In the early stage of the lesion, the cone bundle sign is not obvious, but it can be positive in the period of intermittent claudication. In cases where both cervical and lumbar stenosis are present, the site of the lesion causing the symptoms can be identified by history and physical examination. The main diagnostic criterion is to first observe the patient’s symptomatology, which can be clearly demonstrated by his walking status with intermittent claudication; secondly, to make a guess about the etiology of the patient’s occurrence of such symptoms, and to perform examinations such as X-ray and ultrasound for the relevant guesses. MRI is currently used as a screening test for patients with lower back pain or sciatica.
