Cervical radiculopathy is a common condition caused by foraminal disc herniation or degenerative foraminal stenosis. Although anterior cervical discectomy and fusion is considered the standard treatment, an increasing number of decompression and discectomy procedures via the posterior approach have recently been implemented [1–3]. Surgery performed through the posterior approach has the advantage of avoiding vital organ injury and motion limitation due to spinal fusion [4–6]. However, conventional open microscopic surgery can cause postoperative neck pain and has the disadvantage of posterior neck muscle and ligament injury [7–10]. Additionally, bleeding due to the venous plexus can interfere with the surgical view.
