Evaluation of the effects of lumbosacral dorsal root ganglion pulsed radiofrequency treatment applied via a caudally inserted flexible electrode in radicular pain due to lumbar foraminal stenosis

DRG PRF administered caudally is an effective, safe method in patients with refractory LRP due to foraminal stenosis. Specifically, it provides convenience on patients with instrumentation-related imaging difficulties or those with anatomic disorders such as lordosis, large osteophytes, and severe rotation. In addition, this treatment method can be preferred due to its advantages such as reaching multiple DRG levels with a single needle entry, applying PRF and direct drug injection to the epidural space.
