I have degenerative disc disease with bulging annulus fibrosis and bilateral uncovertebral joint hypertrophy, which results in spinal stenosis at C5-C6. I have been bearing the pain for 5 years and have tried most of non-invasive methods (pain meds, injections, physical therapy, acupuncture, massage, chiropractors) but had no relief. At this point, I am considering surgery. I have seen 3 orthopedic surgeons so far and they all suggested ACDF.
I have done quite a bit of researches regarding this surgery after learning ACDF from the surgeons. I realized that the fusion part of the procedure can vary from surgeon to surgeon. One surgeon’s approach is to use the Zero-P PEEK (by Synthes) for cervical interbody fusion. The surgeon showed me the device, which consists of a plate and a spacer with four screws. I was told that the Zero-P implant is contained within the excised disc space, and unlike anterior cervical plates, it does not protrude past the anterior wall of the vertebral body as do anterior cervical plates. As a result, it is beneficial in reducing soft-tissue irritation and difficulty in swallowing after operation. Besides, Zero-P prevents the risk of adjacent level discs complications in the future because the device remains as far as possible from the adjacent level.
It all sounded good except that I am not sure if the advantages of using Zero-P PEEK are as it claimed. I tried to find more info on it but don’t seem to get much. If anyone had experience/comment on using Zero-P PEEK for cervical fusion, I would appreciate it if you could share with me.
