Is surgery for a herniated lumbar disc risky? Will it be paralyzed? This is a question that all patients are concerned about before surgery. For each patient 0 or 1% risk is 100%, and as a doctor you will do your best to minimize the risk. Spine surgery is relatively risky, so you need to choose an experienced surgeon. In recent years, minimally invasive surgical methods and concepts have entered the field of spinal surgery . On the one hand, minimally invasive radiofrequency ablation is accurately positioned by a C-arm X-ray machine and monitored in real time under digital subtraction, which can measure the nerves within 1 cm of the treatment area and precisely distinguish whether they are motor or sensory nerves. The volume of the treated tissue can be precisely calculated according to the length of the working end, i.e. the volume of the medullary nucleus removed can be precisely controlled. Thus, the nerve compression is released and the root of the disease is eradicated. On the other hand, since surgical magnification equipment (binocular magnifier, operating microscope) has begun to be used in routine spine surgery, the fine structures such as nerve tissue and blood vessels can be clearly identified under the magnified field of view, avoiding medical misinjury, protecting and maximizing the preservation of normal tissues, greatly improving the therapeutic effect of spine surgery, and reducing surgical complications. Furthermore, preoperative assessment of cardiopulmonary function is required to determine whether the patient can tolerate surgery. Patients with hypertension and diabetes can be operated on with smooth control. There is risk in everything we do, and we believe that with care, the risk will go around the edge! We will defend the health of every patient with prudent professional conduct!
