Epidural adhesiolysis with spinal endoscopy is an emerging interventional pain management technique in managing chronic refractory low back and lower extremity pain. However, there is a lack of significant data demonstrating the effectiveness of spinal endoscopic adhesiolysis. This randomized, double-blind controlled trial was undertaken to determine the ability of spinal endoscopic adhesiolysis to reduce pain and improve functional and psychological status. ⋯ Based on the definition that less than 6 months of relief is considered as short-term and longer than 6 months is considered as long-term, a significant number of patients obtained long-term relief. The results showed significant improvement in patients undergoing spinal endoscopic adhesiolysis at 1-month, 3-months, and 6-months, compared to baseline measurements, as well as compared to the control group without adhesiolysis. Spinal endoscopic adhesiolysis with targeted injection of local anesthetic and steroid, is an effective treatment in a significant number of patients without major adverse effects at 6-month follow-up.

Epidural injections with or without steroids are used extensively in the management of chronic spinal pain. However, evidence is contradictory with continuing debate about the value of epidural steroid injections in chronic spinal syndromes. The objective of this systematic review is to determine the effectiveness of epidural injections in the treatment of chronic spinal pain. ⋯ Further, evidence was moderate for caudal epidural injections in managing lumbar radicular pain. The evidence in management of chronic neck pain, chronic low back pain, cervical radiculopathy, spinal stenosis, and post laminectomy syndrome was limited or inconclusive. In conclusion, the evidence of effectiveness of transforaminal epidural injections in managing lumbar nerve root pain was strong, whereas, effectiveness of caudal epidural injections in managing lumbar radiculopathy was moderate, while there was limited or inconclusive evidence of effectiveness of epidural injections in managing chronic spinal pain without radiculopathy, spinal stenosis, post lumbar laminectomy syndrome, and cervical radiculopathy.

The prevalence of illicit drug use by patients in a chronic pain management practice who concomitantly abuse prescription-controlled substances is not known. The purpose of this study was to determine the prevalence of illicit drug use by patients in an interventional pain management practice, based on whether or not there was evidence of simultaneous abuse of prescription drugs. One hundred and fifty patients in an interventional pain management practice who were prescribed controlled substances for pain treatment were selected for assessment of concomitant illicit drug use by urine drug testing. ⋯ Marijuana was the drug of choice in both groups, with 22% in the prescription abuse group and 10% in the non-abuse group. The second most commonly used illicit drug in both groups was cocaine. This study demonstrated a clinically significant use of illicit drugs, particularly marijuana and cocaine in an interventional pain management setting, in patients with or without evidence of concomitant abuse of prescription controlled substances.

To evaluate radiation exposure to the spinal interventionalist performing lumbar discography. A prospective study on four spinal interventionalists who performed 106 consecutive lumbar discograms (levels) on 37 patients with low back pain. Radiation exposure was monitored with the assistance of a radiological technologist (RT) who allocated four (4) dosimetry badges to all spinal interventionalists performing Discograms on consecutive patients being referred for evaluation of possible discogenic pain. ⋯ The mean/cumulative exposure per procedure was 3.66(-/+0.915)/390(-/+9.750) mREM at the "ring" badge, 2.35(-/+0.635)/251(-/+6.275) mREM at the "outside apron" badge, 1.49(-/+0.373)/159(-/+3.975) mREM at the "glasses" badge. A statistically significant higher radiation exposure was found on discograms at the L5/S1 level compared to the L4/5 and L3/4 levels. Our study illustrates that radiation exposure to the spinal interventionalist performing lumbar discography is well within safety limits.

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. ⋯ Ten out of 12 (83%) athletes were able to return to pitching at a level attained prior to RFD. All 12 patients, experienced statistically significant low back pain relief, with a mean pre-RFD VAS of 8.4; mean post-RFD VAS of 1.7; mean pre-RFD R-M score of 12.3; and mean post-RFD R-M score of 22.3. In conclusion, athletes, experiencing lumbar zygapophyseal joint mediated low back pain secondary to zygapophyseal joint synovitis and have failed more conservative management may benefit from radiofrequency zygapophyseal joint denervation followed by a formal rehabilitation program.
