There is no such thing as failure of lumbar disc herniation surgery as far as the doctor is concerned. Instead, the failure is mainly the patient’s feeling, and its symptoms are: 1. Back pain, leg pain, numbness and weakness still exist after the surgery. Doctors cut out the herniated disc through surgery, but the compressed nerves cannot be fully recovered because the nerve cells cannot be regenerated once they are necrotic; 2. Recurrence after surgery, medically recurrence is divided into two cases. Minimally invasive surgery can only remove part of the intervertebral disc, there is a possibility of recurrence and reoccurrence, and the literature reports that the recurrence rate does not exceed 15%. Recurrence is the possibility that the discs in other segments may age and herniate again, requiring surgical treatment.
