In blog discussions about the cervical artificial disc, specifically the Bryan Cervical Disc, it was announced that this disc has now received FDA-approval. One key advantage of cervical arthroplasty and the Bryan Cervical Disc is that patients maintain their natural neck motion as compared to a spinal fusion. (Spinal fusion is the current standard spine surgical treatment for degenerative disc disease.)
A study that I participated in and co-authored, specifically evaluated the patient’s motion – comparing post-operative neck motion. Patients who received the Bryan Cervical Disc in cervical arthroplasty were compared to those that underwent a spinal fusion and anterior discectomy.
This study indicated that the patients that underwent the cervical arthroplasty procedure retained significantly more motion than those that received the spinal fusion. At 24-months the average range of motion for the patients in the cervical arthroplasty group was 7.95 degrees, as compared to 0.87 degrees for the patients in the spinal fusion group. Link here to read an abstract of this study, which was published in the Journal of Spinal Disorders and Techniques.
