Bryan Cervical Disc: Improves disability and arm pain in two level cervical disc disease .
Fusion versus Bryan Cervical Disc in two-level cervical disc disease: A prospective, randomised study
Int Orthop. 2009 Oct;33(5):1347-51. Epub 2008 Oct 28.65 patients were randomized to compare the functional and radiographic outcomes of fusion and Bryan cervical disc replacement for the treatment of two level cervical disc disease. Patients were randomized to undergo either two-level arthroplasty with the Bryan cervical disc prosthesis or two-level anterior cervical discectomy and fusion (ACDF) with iliac crest autograft and plate. The results from a 2 year follow-up demonstrated that both groups produced a significant reduction in the neck disabilities index (NDI) and arm pain; although, the Bryan cervical disc provided a greater percentage improvement in NDI. These findings indicated that the Bryan cervical disc prosthesis is a safe and reliable alternative treatment to ACDF in patients with two level cervical disc disease.
