Contrast flow selectivity during transforaminal lumbosacral epidural steroid injections.

Background: Lumbosacral transforaminal epidural steroid injections (LS-TFESIs) are an accepted procedure used in the comprehensive, conservative care for lumbar disc pathology and/or spinal stenosis induced low back pain with a radicular component. Historically, the terminology used to describe the transforaminal technique of instilling medications into the epidural space and/or exiting structures has varied. These procedures have also been referred to as either diagnostic or therapeutic selective nerve root blocks (SNRBs).

Allergic reactions to gadodiamide following interventional spinal procedures: a report of 4 cases.

Gadodiamide is currently considered a safe alternative for use in interventional spinal procedures in persons with a documented allergic response to iodine-based contrast dyes and with adequate renal function. The most common reactions to gadodiamide are nausea, emesis, and headache. These reactions usually are self-limited and are reported to occur in less than 1% of patients.

Role of radiofrequency denervation in lumbar zygapophyseal joint synovitis in baseball pitchers: a clinical experience.

Lumbar zygapophyseal joints have long been considered a source of low back pain with or without leg pain. The objective of this prospective study was to investigate the therapeutic effectiveness of lumbar zygapophyseal joint radiofrequency denervation (RFD) followed by physical therapy, for the treatment of refractory lumbar zygapophyseal joint mediated low back pain secondary to lumbar zygapophyseal joint synovitis, in baseball pitchers. Participants included twelve male baseball pitchers with a diagnosis of lumbar zygapophyseal joint synovitis mediated low back pain and a subsequent difficulty in pitching.
