Minimally invasive surgery for lumbar disc herniation, is there any harm? 1. Is intervertebral foraminoscopy surgery risky? Any surgery has certain risks, although foraminoscopy is a minimally invasive surgery, there is also a risk of damage to blood vessels and nerves. However, first of all, the surgery is operated under the mirror, so the doctor’s observation of the nerve structure will be clearer than traditional surgery; on the other hand, the doctors are very experienced and will try to avoid damage. Therefore, the damage to the blood vessels and nerves of intervertebral foramenoscopy will not exceed that of open surgery, or even be lower than that of open surgery. 2.What other complications can occur after laminectomy? In addition to vascular or nerve damage, postoperative complications include low cranial pressure headache, wound edema, etc. However, with the improvement of medical technology and the rich experience of doctors, the incidence of such complications has been reduced to a very low level. 3. Will the surgery affect the patient’s motor function if the herniated disc is removed? If the disc is divided into ten parts, the protruding part may take up only one part, so cutting off the protruding part will not have much effect on the patient’s motor function and will not cause instability of the lumbar spine. However, it is not recommended that patients do strenuous activities or bending and lifting after surgery, because every time they do so, the risk of re-protrusion of the disc will increase.
