f caudal neuroplasty using epidural catheter combined with Pulsed Radiofrequency (PRF) versus Pulsed Radiofrequency (PRF) alone
Procedure/SurgeryFluoroscopic guidance was used in all cases with a C-arm system. The patient was prone with a pillow under the lower abdomen. Anteroposterior (AP) images were taken to identify the target level. The C-arm was angled 15-30° to project the spinous process over the contralateral facet ("scotty dog" view). Skin was infiltrated with lidocaine, and a 22-gauge RF cannula was advanced under fluoroscopy. The tip was positioned in the dorsal-cranial quadrant of the intervertebral foramen on lateral images. PRF was applied with 4 cycles at 42°C for 8 minutes after sensory/motor testing. Injections of lidocaine and triamcinolone followed. In caudal neuroplasty, an epidural catheter was placed using the sacral hiatus as a guide. Fluoroscopy confirmed catheter position. Contrast was injected to confirm spread, and hyaluronidase and lidocaine were administered. Afterward, the catheter was removed.
