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. How to check for thoracic disc herniation? 1, medical history can be acute or slow onset, and the symptoms vary in severity, so a comprehensive understanding should be obtained, including previous examinations and treatment profiles. 2.Clinical manifestations Because the size of the sagittal diameter of the spinal canal varies among patients, their symptoms also vary greatly, ranging from general local vague pain to complete paralysis of the lower limbs. 3, imaging examination (1) conventional frontal and lateral radiographs 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 with high-dose water-soluble contrast agent along with CT scan is a more accurate and excellent diagnostic method. If CT is used directly without myelography, the exact segment of the damaged spinal cord will be mistaken. However, most scholars now believe that this type of injury examination should be replaced by MRI, which is also a longitudinal method of looking at the entire thoracic spinal canal. (3) MRI should be performed early in all cases where the disease is suspected. The authors found that MRI examination 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 rarely used or used as a reference. 4, other tests, including electromyography and somatosensory evoked potentials, are not helpful in the diagnosis of thoracic disc herniation.
