Pulsed Radiofrequency of Lumbar Dorsal Root Ganglia for Chronic Post-Amputation Stump Pain

Pulsed radiofrequency of lumbar dorsal root ganglia for chronic post-amputation stump pain.

BACKGROUND Chronic pain following limb amputations is now a recognized chronic pain syndrome usually described in a combination of phantom and stump pain. Both stump and phantom pain continue to be significant treatment challenges. If pharmacotherapy does not provide effective analgesia for stump pain, a clinician has interventional options that frequently give only transient benefit, or have a...

pulsed radiofrequency of lumbar dorsal root ganglion for chronic postamputation phantom pain

two patients with phantom pain were selected for the study. after a positive response to segmental nerve blockade at the l4 and l5 nerve roots, prf was performed on the l4 and l5 dorsal root ganglia. global clinical improvement was good in one patient, with a 40% decrease in pain on the visual analogue scale (vas) in 6 months, and moderate in the second patient, with a 30% decrease in pain scor...

Pulsed Radiofrequency of Lumbar Dorsal Root Ganglion for Chronic Postamputation Phantom Pain

Chronic pain following lower-limb amputation is now a well-known neuropathic, chronic-pain syndrome that usually presents as a combination of phantom and stump pain. Controlling these types of neuropathic pain is always complicated and challenging. If pharmacotherapy does not control the patient's pain, interventional procedures have to be taken. The aim of this study was to evaluate the effica...

Pulsed radiofrequency treatment of the lumbar dorsal root ganglion in patients with chronic lumbar radicular pain: a randomized, placebo-controlled pilot study

BACKGROUND No proof of efficacy, in the form of a randomized controlled trial (RCT), exists to support pulsed radiofrequency (PRF) treatment of the dorsal root ganglion (DRG) for chronic lumbar radicular (CLR) pain. We determined the feasibility of a larger trial (primary objective), and also explored the efficacy of PRF in decreasing pain on a visual analog scale (VAS) and improving the Oswest...
