Developmental spinal stenosis can be determined by CT and MRI. Developmental spinal stenosis is the formation of developmental spinal stenosis when the spinal canal becomes smaller and forms a narrowing of the spinal canal due to contracture of the vertebral plate or surrounding ligaments during the patient’s development. In order to treat the condition in a timely manner, the patient is first given a CT and MRI to observe the progression of the condition. If the patient’s condition is mild, he or she can be treated conservatively first. If the patient has some obvious symptoms, such as decreased muscle strength and loss of reflexes, it is recommended that the patient actively undergoes surgical treatment, mainly laminoplasty and decompression of the laminae. At the same time, the nail rod system should be fixed to prevent spinal slippage. Therefore, once you find the above symptoms, you should go to the hospital in time, complete the examination, make a clear diagnosis, and carry out standardized treatment under the guidance of professional physicians.
