BACKGROUND Degenerative spondylolisthesis is one of the major causes for low back pain. Morphological abnormalities of the zygapophysial joints are a predisposing factor in the development of degenerative spondylolisthesis. Therefore, radiofrequency neurotomy seems to be a rational therapy. OBJECTIVES To determine if radiofrequency neurotomy is effective for patients with low back pain and de...

The post-amputation (pain) syndrome, including stump pain, phantom limb sensation, and phantom limb pain is common but difficult to treat. Refractory stump pain in the syndrome is an extremely challenging and troublesome clinical condition. Patients respond poorly to drugs, nerve blocks, and other effective treatments like spinal cord stimulation and surgery. Pulsed radiofrequency (PRF) techniq...

Chronic orchalgia is a frustrating clinical problem for both the patient and the physician. We present a 17-year-old boy with a bilateral idiopathic chronic intractable orchalgia with failed conservative treatment. For 2 years, he suffered from severe attacks of scrotal pain that affected his daily activities and caused frequent absence from school. Ultrasound-guided pulsed radiofrequency ablat...

To the Editor:—First, I would like to congratulate Van Zundert et al. for their efforts to elucidate one of the putative mechanisms associated with pulsed radiofrequency (PRF), which may help us to understand its analgesic effect in clinical settings. Unfortunately, the explicit and implicit critique in the editorial by Richebé et al. about PRF in general may leave readers not familiar with thi...

In this issue of Neuromodulation, J. Van Zundert et al. have published an article titled, Percutane-ous pulsed radiofrequency treatment of the cervi-cal dorsal root ganglion in the treatment of chronic cervical pain syndromes: A clinical audit (1). The question that our readers might ask is this: Is pulsed radiofrequency neuromodulation? It is the opinion of these authors that it is. The exact ...

Pulsed-radiofrequency neuromodulation (PRF) is a pain management technique that involves placing a needle electrode near nerves and generating electrical current pulses in order to modulate the transduction of somatosensory information through those nerves. This technique evolved from a similar radiofrequency (RF) procedure in which constant current is distributed to a nerve or neural structure...

Corresponding author: [email protected] Conflict of interest: Dr. R Lifford and A Ghazi Nil Dr. E Cosman Jr Scientific Director at Cosman Medical Background: Radicular pain has been successfully treated with pulsed RF to dorsal root ganglia [1]. A transforaminal approach is most commonly used, but may be unsuccessful in cases with abnormal anatomy or implanted metalwork. In these situations,...

Headache occipital neuralgia is an example of pain-disease for which treatment both pharmacological protocols and invasive methods are used. Among the latter, the RF (Radiofrequency) pulse-dose has been of interest for the prospects of analgesic efficacy, safety and patient compliance, although at the moment only data concerning the pulsed RF and not the RF pulse-dose, that represents its evolu...
