Lumbosacral transforaminal epidural steroid injection (TFESI) is helpful for the treatment of lumbosacral radicular pain, but in case of intravascular injection, infrequently serious complication can be developed. Against this backdrop, if there is any difference of frequency of intravascular injection incidence during S1 TFESI between method in anteroposterior view and method in oblique view using Scotty dog, the result can be crucial factor in selecting the approach. In addition, appropriate volume of injection will be checked in each approach.
