Microdiscectomy

Abstract

Lumbar microdiscectomy performed through a tubular retractor is typically the first minimally invasive operation of spine surgeons. The skin incision is placed further lateral for central the disc herniations and close to midline for foraminal herniations. With experience, the yellow ligament can be penetrated sharply. We prefer to limit the disc removal to the herniation, whenever possible, and not violate the central part of the disc. The retractor tube can be angled cranially or caudally as needed, until the entire disc herniation is removed. Confirmation by fluoroscopy after disc herniation removal is recommended.
