Recurrent Disc Herniations
This is unfortunately a definite fact in disc surgery with rates of recurrence (return of the disc hernia in the same site and level) reaching up to 30-40% in some patients. Doing the surgery through the same incision is challenging and carries a higher risk of injury to the nerve or its covering (dura). This is because of peri-neural fibrosis which are adhesions around the nerve tissues and disc material that make all tissues stuck together. In these cases, the transforaminal endoscopic approach is a great solution, as it avoids the original adhesions path by utilising a new path from the side.
