1. Can lumbar disc herniation be treated conservatively? The answer is yes. Generally speaking, about 70% of lumbar disc herniation can be relieved by regular conservative treatment. However, if the symptoms are severe and there is urinary and fecal dysfunction or motor impairment, surgery is required. 2.When does a lumbar disc herniation require surgery? Generally speaking, surgery is required in the following cases: (1) symptoms cannot be relieved by regular conservative treatment for 3 to 6 months and seriously affect work and life; (2) motor dysfunction of the lower limbs; (3) dysfunction of urination and defecation. 3.The film report concludes “lumbar disc herniation”, should we treat it quickly? The lumbar intervertebral disc will degenerate with age, and it will also change due to trauma and other factors, so there can be different degrees of changes in the image, such as bulging and protrusion. However, not every herniation will cause symptoms of lumbar pain. Therefore a herniated lumbar disc found on a physical examination does not mean that you have a lumbar disc herniation. It only indicates the degree of lumbar disc degeneration and reminds patients to pay attention to the maintenance and exercise of the waist. 4.Can lumbar disc herniation be treated minimally invasively? The answer is yes. Depending on the stage of lumbar disc herniation, different minimally invasive treatment methods can be adopted. For patients who have a first attack and whose oral medication or rehydration is ineffective, we use nerve root block under local anesthesia to relieve symptoms on the one hand and clarify the lesion segments on the other. For patients who do require surgery, we use foraminoscopy under local anesthesia to remove the herniated disc and get them out of bed within four hours after surgery, with little damage to normal structures, enabling them to return to work and life as soon as possible. If foraminoscopic surgery is not possible, posterior open-ended nucleus pulposus removal under general anesthesia or epidural anesthesia can be performed to preserve the motor function of the lumbar disc. Some patients with severe lesions require intervertebral fusion surgery. For these patients, we perform minimally invasive intervertebral fusion under access, which protects as much as possible the normal muscle tissue of the low back.
