I'm just over 3 weeks post-op and feel pretty good after having ACDF c5 thru c7. Since the representative showed up at my room with a Bone Growth Stimulator I have been wearing this thing 24x7 with the exception of showers. I have my hopes up that given they used a bracket with screws, this BGS thingy, and taking vitamins that promote, in part, bone health I'm holding out hope I could be fused by 8 weeks post-op. Doc seems to think this could be a possibility. I'm curious as to who has used a BGS immediately following surgery, wore it as much as I'm wearing it, and what his/her healing timeline was for fusion. I was told studies have shown these devices speed up the healing process.
