Most of the patients in whom cervical disk herniation is causing worsening problems or patients who have no relief with conventional conservative measures need cervical spine surgery. Most of the patients need fusion when they need the discectomy to be done from the anterior neck, but a few patients may be eligible for discectomy from the back, and these patients may not need fusion surgery. In some of the patients who need surgery from the anterior neck may be a good candidate for artificial cervical displacement and may not need fusion surgery.
