In clinical practice, herniated discs are a relatively common condition. There can be cervical disc herniation and lumbar disc herniation, which are relatively common. After the appearance of this condition, the patient will first produce a series of nerve damage symptoms clinically, such as the patient will experience numbness and weakness in the limbs, decreased skin sensation, and even pathological reflexes. Secondly, after these conditions appear, a local MRI film can be taken, through which a clear diagnosis can be made. For example, in the sagittal position on the MRI film, the nucleus pulposus can be seen to have a significant posterior protrusion, and the dural sac will show a significant pressure mark. On the cross-sectional view, the nucleus pulposus can be seen in a crescent-shaped change. Therefore, clinically, it is important for a patient to seek prompt medical attention after the appearance of a herniated disc. The doctor can make a clear diagnosis after clinical examination combined with auxiliary examinations for early and correct treatment.
