Diskectomy is the surgical removal of the damaged portion of a herniated disk in your spine. A herniated disk occurs when some of the softer material inside the disk pushes out through a crack in the tougher exterior. This can irritate or compress nearby nerves and cause pain, numbness or weakness.
