Previously, I blogged about the research results of a spine patient study – which evaluated the clinical outcomes of patients who received a Bryan Cervical Disc compared to those that had a standard spinal fusion at 24-months post-operatively. I recently completed a new study, which evaluated these patients 48-months post-operatively. This study will soon be published.
In this study – the functional outcomes of patients at 48-months (4 years) following their spine surgery was evaluated. This study had two groups of patients – one group received a spinal fusion (Anterior Cervical Discectomy and Fusion - ACDF) and the other group received the Bryan cervical artificial disc prosthesis. This spine surgery was for the treatment of radiculopathy and myelopathy, after minimally invasive spine procedures were determined ineffective.
There were 47 patients enrolled in this spine study. Of this group, 21 were enrolled in the Bryan cervical disc arm of the study and their mean age was 40. In the group that received a spinal fusion (control group), there were 26 participants and their mean age was 43.
This study concluded that patients that received the Bryan Artificial Cervical Disc at 48-months, when compared to the control group:
- Had less neck and arm pain,
- Greater mobility,
- Less adjacent segment degeneration, and
- Lower secondary operation rate.
