Comparative Study
Sensory stimulation-guided sacroiliac joint radiofrequency neurotomy: technique based on neuroanatomy of the dorsal sacral plexus.
A retrospective audit and examination of anatomic findings. ⋯ A sensory stimulation-guided approach toward the identification and subsequent radiofrequency thermocoagulation of symptomatic sacral lateral branch nerves appears to offer significant therapeutic advantages over existing therapies for the treatment of chronic sacroiliac joint complex pain.

Spinal cord compression from catheter tip granulomatous masses following intrathecal drug administration may produce devastating permanent neurologic deficits. Some authors have advocated intrathecal catheter placement below the conus medullaris to avoid the possibility of spinal cord involvement. Multiple cases of catheter tip granulomas in the thoracolumbar region have been reported. ⋯ Histologic examination of the mass confirmed a sterile inflammatory mass. It has been suggested that intrathecal catheters be placed below the conus medullaris to avoid the possibility of spinal cord involvement. We present an unusual case documenting devastating permanent neurologic deficits from a catheter tip granuloma in the sacral region.

Facet (zygapophysial) joint pain can be diagnosed by anesthetization of the medial branch divisions of the dorsal rami. In accordance with the criteria established by the International Association for the Study of Pain, lumbar facet (zygapophysial) joints have been implicated as the source of chronic pain in 15% to 45% of the patients with chronic low back pain. The reasons for the wide variations have not been systematically evaluated. ⋯ A false-positive rate of 17% in patients with low back pain only and 21% in patients with involvement of multiple regions of the spine was demonstrated with single blocks. This study demonstrated a lower incidence of facet joint pain in patients with spinal pain of a single region in the low back compared to the patients with multiple region involvement of the spine (21% vs 41%), in an interventional pain management setting. These results may not be extrapolated to the general population or chronic low back pain population at large.

Randomized Controlled Trial Comparative Study Clinical Trial
A randomized trial of combined manipulation, stabilizing exercises, and physician consultation compared to physician consultation alone for chronic low back pain.
A prospective randomized controlled trial. ⋯ The manipulative treatment with stabilizing exercises was more effective in reducing pain intensity and disability than the physician consultation alone. The present study showed that short, specific treatment programs with proper patient information may alter the course of chronic low back pain.

Randomized Controlled Trial Clinical Trial
Randomized controlled trial of education and feedback for implementation of guidelines for acute low back pain.
The effect of clinical guidelines on resource utilization for complex conditions with substantial barriers to clinician behavior change has not been well studied. We report the impact of a multifaceted guideline implementation intervention on primary care clinician utilization of radiologic and specialty services for the care of acute low back pain. ⋯ Implementation of an education and feedback-supported acute low back pain care guideline for primary care clinicians was associated with an increase in guideline-consistent behavior. Patient education materials did not enhance guideline effectiveness. Implementation barriers could limit the utility of this approach in usual care settings.
