I would agree that with significant pain and weakness associated with a large herniation at C6-7, a surgical procedure would be indicated.
The three choices are not bad but there is a ranking order in my opinion. The cervical ADR will help maintain range of motion but will not help with adjacent segment disease (ASD-the wearing out of the level above or below). This adjacent segment disease is most likely from the genetics of the discs and not from the surgery. Also, ADRs will eventually wear out and have to be replaceD by an ACDF somewhere in the future. It might be 10 or 20 years (or possibly never).
The standard ACDF with allograft (donor bone) is probably the most successful of the three surgeries. The fusion rate is pretty good and the “external plate” has almost never been a problem in my hands.
The Zero-P is a spacer made of plastic (PEEK) and metal. As such, this reduces the biologically active fusion surface area and makes this device less likely to fuse successfully. This would be the last on the list if I were considering this surgery.
