Seems to me what this says is that no volume over 0.5cc can be considered selective. The problem is, I suspect most will read that to also mean 0.5cc IS selective. What Furman says is that the CONTRAST INITIALLY stays unilateral and within one level if injected at 0.5cc or less. No comment is made about the local anesthetic, nor what happens to the solutions in question once you get the patient up. To me, this is a dangerous article, not because of what it actually concludes, but rather because of what folks assume it implies. For my money, there remains no such thing as a truly selective nerve root block, and anyone who allows a surgeon to rely on such nonsense in his pre-operative staging is doing their patient a huge disservice.
