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

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 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 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...

Response to pulsed and continuous radiofrequency lesioning of the dorsal root ganglion and segmental nerves in patients with chronic lumbar radicular pain.

OBJECTIVES We aimed to prospectively evaluate the response and safety of pulsed and continuous radiofrequecy lesioning of the dorsal root ganglion/segmental nerves in patients with chronic lumbosacral radicular pain. METHODS Seventy-six patients with chronic lumbosacral radicular pain refractory to conventional therapy met the inclusion criteria and were randomly assigned to one of 2 types of...

LETTER TO THE EDITOR Investigating the Effects of Pulsed Radiofrequency on Dorsal Root Ganglion in Chronic Lumbar Radicular Pain Patients: Is It Not Important

It is interesting to read the paper by Koh et al. on the investigation of the pulsed radiofrequency (PRF) of the dorsal root ganglion (DRG) in patients of chronic lumbosacral radicular (CLR) pain [1]. It is noteworthy that the authors attempted to perform a controlled trial on a challenging topic. However, I am afraid that the study design, results, and conclusions have further “muddied the wat...
