Discogenic low back pain is a common cause of chronic low back pain that remains a treatment challenge. The innervation and transmission of nociceptive information from painful lumbar discs has only recently been better described. ⋯ Radiofrequency lesioning of the L2 ramus communicans seems to offer partial relief for patients suffering from discogenic pain. Further studies are needed to confirm our results.

To assess whether unilateral L2 infiltration with local anesthetic can be used to identify patients who will have negative discograms and thus eliminate the need for the discogram. Discogenic low-back pain is considered to have afferent pathways in the sinuvertebral nerves, mainly originating from the ventral rami of the spinal nerves. There is evidence that pain arising from the lower lumbar intervertebral discs may be transmitted through the sympathetic afferent fibers contained in the L2 spinal nerve root. Provocative discography, within the context of other clinical data, is the current "gold standard" by which to diagnose discogenic low-back pain, but a far more invasive procedure than L2 infiltration. ⋯ The results showed that unilateral L2 infiltration is not predictive of discogenic low-back pain when compared to discography, the current "gold-standard" for diagnosis.

The aim of this study was to assess the prevalence of neuropathic pain among patients suffering from chronic low back pain using the Leeds assessment of neuropathic symptoms and signs (LANSS) pain scale. ⋯ The ability to identify neuropathic pain mechanisms should lead to individualized treatment resulting in improved pain control in this group of patients with chronic low back pain.

Nonradicular low back pain can be a difficult entity to accurately diagnose and treat. Facet joints, muscle, ligaments, and fascia have all been reported to be etiologies of acute and chronic low back pain. However, the facet joint as a source of low back pain is controversial. The diagnosis of facet joint pain is made by diagnostic facet joint or median nerve branch injections with a local anesthetic. The purpose of this study was to determine if the results of diagnostic facet joint injections are influenced by the technique used to perform these injections. ⋯ The results of this study demonstrated that local anesthetic injections are useful for the diagnosis of nonradicular low back pain but may yield false positive results with respect to lumbar facet pain depending upon the technique utilized.

Intradiscal electrothermal annuloplasty (IDET) is an effective treatment for chronic discogenic low back pain (LBP). However, efficacy of IDET for the treatment of referred leg pain has not been examined. This study was performed to assess the long-term efficacy of IDET for the treatment of referred leg pain in chronic discogenic LBP patients. ⋯ A relatively large number of LBP patients who underwent IDET (84%) presented with referred leg pain without sciatica. The IDET procedure afforded improvements in leg pain that correlated well with improvements in back pain (0.75/4 and 0.88/4, respectively). These data suggest that IDET may relieve associated limb pain in chronic discogenic LBP patients.
