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 spine stenosis are present, the lesion site causing the symptoms can be identified by history and physical examination. 1, lumbar spine X-ray plain film alone cannot directly respond to the presence of disc herniation, but degenerative changes such as narrowing of the intervertebral space and vertebral body edge hyperplasia are sometimes seen on the X-ray film, which is an indirect indication that some patients can have spinal deflection and scoliosis. In addition, X-ray plain film can detect the presence of tuberculosis, tumors and other bone diseases, which has important differential diagnostic significance. 2.CT examination 3.Magnetic resonance imaging (MRI) MRI can comprehensively observe whether the spinal cord is diseased, and through the sagittal images at different levels and the transverse images of the involved spinal cord, in addition to identify the presence of other occupying lesions in the spinal canal. 4.Other electrophysiological examinations (electromyography, nerve conduction velocity and evoked potentials) can help determine the extent and degree of nerve damage and observe the effect of treatment. Laboratory tests are mainly used to exclude some diseases and play a role in differential diagnosis.
