A multitude of evidence supporting the beneficial effects of spinal cord stimulation (SCS) in patients suffering from chronic pain syndromes following spinal surgery has been published in the last decade. Evidence is scarce, however, for the use of high frequency SCS (HF-SCS) in the treatment of surgery naïve patients suffering from lower back pain (LBP). ⋯ In this prospective cohort of surgery naïve patients, we were able to show good efficacy of HF-SCS with mean NRS reductions of 4.13 and 6.2 for back and leg pain, respectively, after a mean follow-up of 10 months.

Failed back surgery syndrome (FBSS) affects 40% of patients following spine surgery with estimated costs of $20 billion to the US health care system. The aim of this study was to assess the cost differences across the different insurance providers for FBSS patients. ⋯ Our study demonstrates a significant difference in overall costs between various insurance providers in the management of FBSS, with Medicaid-insured patients having lower overall costs compared to Commercial- and Medicare-patients. SCS is cost-effective across all insurance groups (Commercial > Medicaid > Medicare) beginning at two years and continuing through nine-year follow-up. Further studies are necessary to understand the cost differences between these insurance providers, in hopes of reducing unnecessary health care expenditures for patients with FBSS.

Burst spinal cord stimulation (SCS) has been reported to reduce back pain and improve functional capacity in Failed Back Surgery Syndrome (FBSS). However, its mechanism of action is not completely understood. Systemic circulating cytokines have been associated with the development of chronic back pain. ⋯ Burst SCS increased systemic circulating anti-inflammatory IL-10, improved FBSS back pain and back pain associated co-morbidities like disrupted sleep architecture and depressive symptoms in FBSS patients. Thus, suggesting a possible relationship between burst SCS and burst-evoked modulation of peripheral anti-inflammatory cytokine IL-10 in chronic back pain.
