Percutaneous pulsed radiofrequency treatment of dorsal root ganglion for treatment of lumbar facet syndrome.

Objectives: Percutaneous radiofrequency denervation of the medial dorsal branch is often used for treatment of chronic low back pain originating from intervertebral facets, which is sometimes associated with a low success rate and a higher incidence of recurrence of pain. We theorized that implementing pulsed radiofrequency treatment to dorsal root ganglion would increase the probability of successful pain relief.

Patients And Methods: 150 patients diagnosed with CLBP of a confirmed facet origin were included in a prospective randomized controlled trial and were randomly divided into three equal groups, the first was submitted to percutaneous pulsed radiofrequency treatment of the dorsal root ganglia, the second underwent percutaneous radiofrequency denervation of the medial dorsal branch and the third was a control group that did not receive any radiofrequency treatment.

Predictive Factors for Seizures Accompanying Intracranial Meningiomas.

Objective: Seizures represent a common manifestation of intracranial meningiomas. Their predictive factors before and after excision merit studying.

Materials And Methods: Patients having intracranial meningioma were prospectively studied.
