A new study published in Clinical Spine Surgery compares the Bryan Cervical Disc to anterior cervical discectomy and fusion, measuring adjacent segment disease after surgery.
There were 70 patients included in the study, which occurred at two centers as part of an FDA investigational device exemption trial for the Bryan cervical disc. Study authors found:
1. Both patients who underwent disc replacement and those who underwent fusion reported a decrease in disc height over time.
2. The change in disc height wasn't significant in either group after surgery.
3. Study authors concluded that both groups experienced similar rates of adjacent segment disease. "Our measurement technique is reliable and to the best of our knowledge not previously reported in the literature," concluded the study authors.
