Background. Spinal cord stimulation (SCS) is effective in reducing pain from a number of differing medical conditions that are refractory to other, more conservative treatments. Much is written in the literature regarding efficacy and safety of SCS; however, no one to our knowledge has compared and reported safety and efficacy of SCS when using differing manufactured SCS devices. We undertook such a preliminary evaluation. ⋯ Conclusions. Spinal cord stimulation improves pain, sleep, and function in patients with intractable pain. Because of the low number of patients evaluable in this study, we believe that conclusions should not be made regarding the effect of technology on outcomes or safety. We believe that an analysis of this type in larger populations is warranted to understand the role, if any, that present-day technology has on outcomes of SCS.

Background. Lyme disease is caused by Borrelia, a bacterium transmitted by the bite of a deer tick. A slow developing encephalopathy or an axonal polyneuropathy with distal paresthesia and spinal or radicular pain rarely occurs and can be hard to treat. ⋯ Results. After 18 months of therapy and follow-up, this patient's analgesia, as a result of SCS, continues to be excellent, with almost complete subjective pain relief and cessation of adjuvant analgesic medication. Conclusions. SCS may be efficacious for the treatment of neuropathic pain due to Lyme disease.

The patient with neurogenic claudication resulting from lumbar spinal stenosis who fails to experience satisfactory relief from nonsurgical measures has limited treatment options. Lumbar epidural steroid injections and surgical laminectomy are generally accepted alternatives for the patient with moderate to severe symptoms. ⋯ Sufficient medium- and long-term data are lacking, however, particularly with respect to durability of symptomatic relief and the risk of device migration or dislocation. Although interspinous process spacers are a promising new technology, the results of longer-term clinical follow-up studies are needed to more clearly define their role in the management of lumbar spinal stenosis.

Objectives. Spinal cord stimulation has been used extensively for failed back surgery syndrome, although dominant axial low back pain is difficult to treat effectively with this modality. The use of a surgically placed, double, quadripolar lead may result in better paresthesia of the low back, therefore enhancing outcomes in this difficult to treat population. Materials and Methods. Accordingly, this prospective study was designed to assess the effectiveness of placing such a lead at the T8-T10 level under general anesthesia without intraoperative testing for concordancy of paresthesia distribution. ⋯ The ability to lead a more active and social life was increased and 85% of patients said they would undergo spinal cord stimulation again. Placing the lead higher in the spinal canal (T8) resulted in a tendency for better paresthesia coverage of the low back when compared to lower lead placements. Conclusions. Placing a double quadripolar paddle lead under general anesthesia resulted in good clinical outcome similar to other implant techniques.

Comparative StudyPrevalence of facet joint pain in chronic low back pain in postsurgical patients by controlled comparative local anesthetic blocks.
To evaluate the prevalence of facet joint pain in patients with chronic low back pain (CLBP) after surgical intervention(s). ⋯ Facet joints are clinically important pain generators in a small but significant proportion of patients with recurrent CLBP after various surgical intervention(s).
