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.

Review Case Reports
Spinal Cord Stimulation for Spasticity: Historical Approaches, Current Status, and Future Directions.
Millions of people worldwide suffer with spasticity related to irreversible damage to the brain or spinal cord. Typical antecedent events include stroke, traumatic brain injury, and spinal cord injury, although insidious onset is also common. Regardless of the cause, the resulting spasticity leads to years of disability and reduced quality of life. Many treatments are available to manage spasticity; yet each is fraught with drawbacks including incomplete response, high cost, limited duration, dose-limiting side effects, and periodic maintenance. Spinal cord stimulation (SCS), a once promising therapy for spasticity, has largely been relegated to permanent experimental status. ⋯ With improved energy-source miniaturization, tailored control algorithms, novel implant design, and a clearer picture of the pathophysiology of spasticity, we are poised to reintroduce and test SCS in this population.

Multicenter Study Observational Study
Peripheral Nerve Stimulation in the Treatment of Chronic Pain Syndromes From Nerve Injury: A Multicenter Observational Study.
Assessing the feasibility, technical implications, and clinical benefits of peripheral nerve stimulation (PNS) performed by an implantable pulse generator (IPG) located close to the stimulation site. ⋯ Successful PNS was achieved with a stimulation system designed for peripheral location. This new technology reduced the incidence of lead-related adverse events and the energy cost of the treatment.

Ziconotide use in intrathecal drug therapy (IDT) has been limited by dosing related side effects. We examine our experience with ziconotide as a first line IDT monotherapy in patients with chronic pain and present our low and slow dosing algorithm aimed at reducing these patient experienced side effects while adequately managing pain. ⋯ We present our experience with low and slow ziconotide IDT as a first-line monotherapy, which showed no side effects resulting in discontinuation of the medication at three-month follow-up. Using a conservative dosing strategy, we were able to effectively treat 53% of patients.

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.
