Review Meta Analysis
Cylindrical vs Paddle Leads in Spinal Cord Stimulation for the Long-term Treatment of Chronic Pain: A Systematic Review and Meta-analysis.
This systematic review compares the long-term efficacy of cylindrical-lead spinal cord stimulation (CL-SCS) vs paddle-lead spinal cord stimulation (Paddle-SCS) for chronic pain management. ⋯ Paddle-SCS offers superior pain reduction (as measured by the VAS) and a lower migration rate, but a higher infection risk compared with CL-SCS. CL-SCS showed better outcomes as measured by the NRS. The choice between Paddle-SCS and CL-SCS should be individualized according to patient-specific factors and treatment goals. Further research with rigorous study designs is needed to provide clearer comparisons between these interventions.

Review Meta Analysis
Noninfectious Complications of Dorsal Root Ganglion Stimulation: A Systematic Review and Meta-Analysis.
Dorsal root ganglion stimulation (DRGS) has emerged as a promising treatment for chronic neuropathic pain. However, its safety and complications are not fully understood, with existing literature primarily based on case reports, observational studies, and data base analyses. This systematic review and meta-analysis aims to assess the prevalence of noninfectious complications associated with DRGS, focusing on the trial phase, postimplantation period, and revisions, while identifying risk factors for these outcomes. ⋯ DRGS shows a safety profile comparable to that of spinal cord stimulation, with similar rates of lead migrations and fractures. Improvements in surgical techniques, technology, and clinician expertise are expected to reduce complications. Future research should standardize reporting practices and detail implantation techniques to better understand and refine best practices in DRGS implantation.
