Introduction: Spinal Cord Stimulation (SCS) is an efficacious treatment for various chronic pain syndromes culminating predominantly into spinal nerves before reaching higher
pain centers. To improve intra-operative electrode placement several groups have advocated the use of intraoperative neuromonitoring (IONM) for localization of the spinal cord midline. In our study we present the case series of patients undergoing stimulator placement with consistent EMG intraoperative testing, with an emphasis
on examining reoperation rates and complications.
Methods: Following approval from IRB, we retrospectively collected data on standard demographics, preoperative diagnoses, prior spine surgeries, electrode manufacturer, blood loss, complications, and patient outcome.
Results: of patients had prior spine surgery, which was associated with higher rates of reoperation (p=0.019). The mean latency between initial SCS implantation and
revision surgery was 14.6 months with a standard deviation of 17.2 months and its median time was 280 days. There were 13.6% of complication rate. Common
complications that lead to reoperation included migrated electrode or failed
Conclusions: Our retrospective chart review of 103 patients indicates that patients receiving SCS implantation in conjunction with EMG monitoring have low complication rates and
rarely return to the OR for electrode repositioning or removal.
Patient Care: This abstract explains the role of EMG to make SCS placement more efficient.
Learning Objectives: To learn the role of EMG in SCS placement
