Clinical Practice Variations in Interventional Treatment of Chronic Lumbosacral Radicular Pain Among Registered Dutch Pain Specialists: A National Survey

A total of 125 pain specialists (response rate: 29%) completed the questionnaire. The most notable finding was that only 27% reported routinely performing prognostic selective nerve root blocks with local anesthetics prior to pulsed radiofrequency (PRF) treatment in patients with chronic lumbosacral radicular pain. Lidocaine was the preferred local anesthetic (n = 72, 63%). PRF was identified as the cornerstone of therapeutic interventional treatment by 81% of respondents (n = 93), and 40% (n = 46) reported combining PRF with corticosteroid administration.
