Surgical site infections (SSIs) are associated with significant healthcare costs and morbidity. Limited research exists specific to the prevention of spinal cord stimulation (SCS) SSIs. The objectives of this international survey were to examine current infection control practices for SCS trials and implants and to compare reported responses with evidence-based recommendations. ⋯ The survey provided significant insight into current practices and will assist in the development of specific SCS infection control policies. Based on the survey, further education is warranted on infection control strategies for physicians performing spinal cord stimulator trials and implants.

Spinal cord stimulation is commonly used to treat medically intractable pain. Different stimulation designs are used to obtain pain suppression such as tonic stimulation, high frequency stimulation, and burst stimulation. Preliminary analysis of the same data used in this study demonstrated that burst stimulation likely modulates the medial pain pathways in contrast to tonic stimulation. The question arises what different and common supraspinal mechanisms burst and tonic stimulation use. ⋯ These data suggest that burst and tonic stimulation both modulate the descending pain inhibitory system (via pgACC), as well as a self-referential contextual (via PCC) aversive memory system (via parahippocampus). However, burst normalizes the pain supporting/suppressing balance in contrast to tonic mode by a greater effect on the dACC.

Randomized Controlled Trial Multicenter Study
Prospective, Multicenter, Randomized, Double-Blinded, Partial Crossover Study to Assess the Safety and Efficacy of the Novel Neuromodulation System in the Treatment of Patients With Chronic Pain of Peripheral Nerve Origin.
Currently available central nervous system treatment strategies are often insufficient in management of peripheral neuropathic pain, prompting a resurgence of neuromodulation focused on peripheral pain. A new peripheral nerve stimulation device was investigated in a prospective, randomized, double blind, crossover study, looking specifically at efficacy and safety, with Food and Drug Administration oversight. ⋯ The novel peripheral nerve stimulation device is a safe and effective treatment strategy to address neuropathic pain of peripheral nerve origin.

Spinal cord stimulation (SCS) has been proven effective for multiple chronic pain syndromes. Over the past 40 years of use, the complication rates of SCS have been well defined in the literature; however, the incidence of one of the most devastating complications, spinal cord injury (SCI), remains largely unknown. The goal of the study was to quantify the incidence of SCI in both percutaneous and paddle electrode implantation. ⋯ Our study shows that the overall incidence of SCI in SCS is low (2.13%), supporting that SCS is a safe procedure. No significant difference was found in the rates of SCI or spinal hematoma between the percutaneous and paddle groups. Further studies are needed to characterize the mechanisms of SCI in SCS and long-term outcomes in these patients.
