ADR is indicated for DDD, in fact it was at least in part intended for DDD with no other damage to the vertebral structures. As for why Allan's doc doesn't want to use fusion, which was the gold standard, I can only guess. Is he making judgements based on Allan's age and deciding that the likelihood of adjacent level problems is far too high to justify fusion at his two worst levels? If so, he might be willing to pursue fusion if you would later puruse ADR at other levels, but there aren't many that are willing to use a mix of fusion and ADR.

Allan, if your facet injections show your facets are a pain generator in themselves, your odds are poor for ADR at that/those levels. Some here did have their facet pain diminish with ADR but most seem to have either held steady or gotten worse if they were compromised to start.
