Epidural steroid injections are the most commonly used procedures to manage chronic low back pain in interventional pain management settings. The overall effectiveness of epidural steroid injections has been highly variable, and in the role has not been evaluated in patients discographically evaluated. One hundred consecutive patients, without evidence of disc herniation or radiculitis, who had failed to respond to conservative management with physical therapy, chiropractic and/or medical therapy, underwent discography utilizing strict criteria of concordant pain, and negative adjacent discs, after being judged to be negative for facet joint and/or sacroiliac joint pain utilizing comparative local anesthetic blocks. ⋯ The study showed that at 1 month, 100% of the patients evaluated showed significant improvement in both groups; this declined to 86% at 3 months in Group I, but remained at 100% in Group II, declining to 60% and 64% at 6 months in Group I and Group II, respectfully, with administration of one to three injections. Analysis with one to three injections, which included all (62) patients showed significant relief in 71% and 65% of the patients at 1 month, in 67% and 65% at 3 months, and in 47% and 41% at 6 months, in Group I and Group II, respectively. In conclusion, caudal epidural injections with or without steroids is an effective modality of treatment in managing chronic, persistent low back pain failing to respond to conservative modalities of treatments, in patients negative for facet joint and sacroiliac joint pain, whether positive or negative, on evaluation with provocative discography.

The prevalence of persistent low back pain secondary to involvement of lumbosacral facet joints has been described in controlled studies as varying from 15% to 52% based on types of population and settings studied. Previous studies have shown variances in elderly populations, and postlumbar laminectomy patients. But no variations were observed in obese patients or patients with somatization disorder. ⋯ The prevalence of facet joint pain in men was 38% (95% CI, 29% to 47%) compared to 43% (95% CI, 36% to 50%) in women; 43% (95% CI, 33% to 53%) in non-smokers, compared to 41% (95% CI, 30% to 52%) in heavy smokers; and 28% (95% CI, 18% to 38%) in occupational injury patients compared to 44% (95% CI, 36% to 52%) with a history of gradual onset. False-positive rates varied from 28% to 46%. In conclusion, based on the results of this evaluation, women and men, smokers and nonsmokers suffer with similar prevalence rates of facet joint pain in chronic low back pain; whereas occupational injury patients suffer with lesser prevalence (28%) compared to patients with gradual onset (44%) of low back pain.

This study was designed to evaluate the psychological status of 50 individuals without chronic pain and without psychotherapeutic drug therapy, Group I, the control group; and Group II, a chronic pain group with 100 chronic pain patients. All the participants were tested utilizing Millon Clinical Multiaxial Inventory III (MCMI-III). Results were analyzed and compared for various clinical personality patterns, including personality traits and personality disorders; severe personality pathology for schizotypal, borderline and paranoid personality pathology; and multiple clinical syndromes, including generalized anxiety disorder, somatization disorder, major depression, bipolar manic disorder and dysthymic disorder, etc. ⋯ The prevalence of psychological disorders in the control group was 24%, compared to 55% in chronic pain group. In conclusion, this evaluation showed that clinical personality patterns are present in both groups of patients. Psychological abnormalities such as generalized anxiety disorder, somatization disorder, and major depression are commonly seen in chronic pain patients.

Epidural steroid injections are the most commonly used procedures to manage chronic low back pain in interventional pain management settings. Approaches available to access the epidural space in the lumbosacral spine include the interlaminar, transforaminal, and caudal. The overall effectiveness of epidural steroid injections has been highly variable. ⋯ The study also showed cost effectiveness of this treatment, with a cost of $ 2550 for 1-year improvement of quality of life. In conclusion, caudal epidural injections with steroids or Sarapin are an effective modality of treatment in managing chronic, persistent low back pain that fails to respond to conservative modalities of treatments and is also negative for facet joint pain. The treatment is not only effective clinically but also is cost effective.

This study was designed to investigate radiation exposure to a physician performing fluoroscopically guided caudal epidural steroid injections. The prospective study design included 100 consecutive fluoroscopically guided caudal epidural steroid injections performed on patients with radiculitis from either herniated nucleus pulposus or lumbar spinal stenosis. Radiation exposure was monitored with the assistance of a radiological technologist (RT) who allocated four dosimetry badges to all physicians performing fluoroscopically guided caudal epidural steroid injections on consecutive patients being treated for radicular pain. ⋯ The RT's average exposure during these procedures was below the limit of detectability. Radiation exposure to the physician needs to be considered and minimized in the performance of spinal interventional procedures. Our study demonstrates that radiation exposure to the physician performing fluoroscopically guided caudal epidural steroid injections is well within safety limits when he/she adheres to proper technique.
