A herniated disc can cause intercostal scapular girdle pain by compressing the spinal nerve roots at the root canal nerve outlet. Intercostal scapular pain is a clinical manifestation of thoracic disc herniation. Chronic column strain, injury and postural malposition, forced position can trigger the disease; degeneration of the thoracic vertebrae is also one of the causes of the disease. What are the examination methods for thoracic disc herniation? 1.X-ray examination Conventional frontal and lateral X-ray plain films of the thoracic spine are preferred; it is reported that 20% to 50% of patients with thoracic disc herniation have calcified intervertebral discs in the spinal canal. 2, myelography Myelography with high-dose water-soluble contrast agent at the same time with CT scan is a more accurate and excellent diagnostic method, such as not first myelography, but directly with CT examination, will be wrong the exact segment of the damaged spinal cord, but most scholars now believe that such an injury examination should be replaced by MRI examination, because the latter is also a longitudinal observation to estimate the entire thoracic spinal canal. The authors found that MRI is the most effective measure for early diagnosis and timely treatment of this disease. In addition, although myelography and CT examination are also helpful for the diagnosis of this disease, they are not as confirmatory as MRI examination, so they should not be used as the first choice and are less frequently used or only used for reference.
