TF vs SNRB
SteveE-Sorry it has taken me so long to get back to you, but I did not know you had further questions. Mark usually cotacts me if there is a question, but this one I'm sure just flew under the radar. With the info you gave, I'll do my best...first, many interventionalists don't know the difference between the two blocks much less an assistant in his office. For all you know, he wanted a SNRB, but because the terms are used so interchangably even in the field, it is hard to say what was desired or performed. Also, if your physical exam and radiographic findings are consistant with a problem at L4-5, there may be no need to do a SNRB...your doctor may be confident anatomically, and a TF would be appropriate and save you a block. The best idea is to just get a clairification from your doc. Good luck
