Success of any surgery depends upon the objective with which it is performed. Discectomy isa simple procedure in which we remove a portion of the disc that is causing pressure to the nerves and damaging it. Relief of the nerve pain is the objective. Therefore the patient is relieved of the leg pain or weakness or tingling that is bothering him. Sometimes the surgery is done only to prevent further damage to nerves as nerve damage is often irreversible. Therefore it is important before surgery to discuss the expectations of the surgery.
