Postlumbar surgery syndrome (PLSS; failed back syndrome) is characterized by persistent pain in the lower back or lower extremities after spinal surgery. It occurs in 10-40% of patients who undergo a back surgery. The recently introduced pulsed radiofrequency (PRF) technique is widely used to provide relief from chronic pain and studies have shown that PRF stimulation can be used to control neuropathic pain by placing the needle electrodes into the caudal epidural space The aim of this study is evaluation of the effect of ultrasound guided caudal epidural pulsed radiofrequency stimulation in patients with chronic lumbosacral radicular pain due to postlumbar surgery syndrome.

| caudal epidural pulse radio frequency | Procedure | A needle is inserted into the caudal epidural space under ultrasound guidance and pulse radiofrequency is administered at 5 Hz using a 5. ms pulse width for 600 seconds at 55 V. |
| Measure | Description | Time Frame |
|---|---|---|
| Numeric Rating Scale(NRS) (0-10) | The 11-point NRS consists of numbers between 0 and 10 where 0 indicates "no pain" and 10 indicates "maximum pain." The patient is instructed to identify one number between 0 and 10, which is best representative of their pain intensity. | before procedure |
