Only 10% of the patients with lumbar disc herniation need surgery. Because the patients themselves and their families do not understand the operation process, they are very worried before surgery, and even afraid of surgery, saying: now they can still move, what if they are paralyzed in bed after surgery? Most of the patients delayed again and again before surgery, and never operated even if they dragged their legs as a last resort. The main concern of patients and their families before surgery is whether they will be paralyzed after surgery. From the point of view of the current technological development, as long as the doctor is operating under direct vision according to conventional technology, for lumbar spine surgery, paralysis is not easy. But it is impossible to ask anyone to guarantee 100 percent. In any industry, engaged in professional technology understand this, even if there is a 100% certainty do not dare to boast. We can only say that we have taken into account all the risks that may be encountered during the operation, minimizing all possible surgical risks and avoiding accidents as much as possible. Preoperative risk assessment is very important. Through a comprehensive preoperative examination, the patient’s liver, kidney, and cardiopulmonary function reserves are evaluated, and precautions are taken before surgery for possible intraoperative conditions, and relevant situations are consulted by specialists. The risk of surgery is basically controllable, but not absolute. I always emphasize one point with the patient’s family before surgery: safety first, without safety as a guarantee, it is meaningless to do like a flower; under the premise of safety, make the surgery as good as possible.
