Lumbar disc herniation is a common disease and one of the main causes of low back pain, and it ranks first among the non-traumatic factors causing labor loss. There are numerous treatments for lumbar disc herniation, which in general can be divided into three categories: conservative treatment, minimally invasive treatment and open surgical treatment. Conservative treatment is the basis of treatment for lumbar disc herniation, and about 80% of patients will experience significant reduction or disappearance of symptoms after regular conservative treatment. When the regular conservative treatment is ineffective for 2 months or the effect is not good, minimally invasive treatment or open surgical treatment is feasible. The specific use of minimally invasive or surgical treatment is mainly determined by the type and degree of disc herniation and the presence of combined bony spinal stenosis and posterior longitudinal ligament calcification, etc. Therefore, it is necessary to perform clear imaging examinations (CT, MRI) before treatment. The efficiency of minimally invasive treatment can reach more than 90% if the indications are strictly mastered. Common treatment methods for lumbar disc herniation: 1. conservative treatment (traction, massage, acupuncture, herbal fumigation, dehydration, etc.); 2. minimally invasive treatment (ozone, nerve root closure, laser, discoscopy, etc.); 3. open surgical treatment. Departments capable of treating lumbar disc herniation: 1. physiotherapy department (conservative treatment is the main treatment); 2. pain department (conservative treatment is the main treatment, some hospitals pain department can be minimally invasive treatment); 3. interventional radiology department (minimally invasive treatment is the main treatment); 4. spine surgery (open surgery is the main treatment, some hospitals can be minimally invasive treatment). Common imaging methods for lumbar disc herniation: 1, X-ray, which can provide limited information; 2, CT, which can make a clear diagnosis, especially for herniated nucleus pulposus calcification, etc.; 3, MRI, which has high soft tissue resolution and can scan in multiple directions, is the best test method for diagnosing disc herniation.
