简要总结
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.

结局指标
主要结局
Numeric Rating Scale
时间窗: 8 weeks after procedure
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.
Numeric Rating Scale(NRS) (0-10)
时间窗: before procedure
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.
Numeric Rating Scale
时间窗: 2 weeks after procedure
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.
Numeric Rating Scale
时间窗: 4 weeks after procedure
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.
