The indications for minimally invasive disc herniation surgery are mainly for those with serious conditions and obvious nerve root compression symptoms. 1. Serious condition: low back and leg pain and other symptoms seriously affecting daily life and work, and ineffective after drug treatment and physical therapy. 2. People with obvious symptoms of nerve root compression: people with typical symptoms of nerve root compression in the lower limbs, such as numbness in the legs, feet or perineum, defecation obstacles, foot drop, weakness of the lower limbs and so on. Currently, minimally invasive surgery commonly used for clinical disc herniation mainly refers to percutaneous endoscopic discectomy. The indications for surgery are as above, but whether minimally invasive to surgical treatment can be carried out still needs to be strictly grasped by professional doctors in conjunction with the results of imaging examinations. It is important to go to the hospital in time for examination, clear diagnosis and treatment under the guidance of the doctor.
