Abstract
PURPOSE OF REVIEW Cervical spine pain with or without radicular symptoms is a common condition leading to high utilization of the healthcare system with over 10 million medical visits per year. Many patients undergo surgical interventions and unfortunately are still left with neck and upper extremity pain, sometimes referred to as "Failed Neck Surgery Syndrome." When these options fail, cervical spinal cord stimulation can be a useful tool to decrease pain and suffering as well as reduce prescription medication use. RECENT FINDINGS Spinal cord stimulation is a well-established therapy for chronic back and leg pain and is becoming more popular for neck and upper extremity pain. Recent studies have explored cervical spinal cord stimulation with successful outcomes regarding improved pain scores, functional outcomes, and reduction of prescription medication use. Continued research into cervical spinal cord stimulation is essential for maximizing its therapeutic potential for patients with chronic neck and upper extremity pain. This review highlights the importance of cervical spinal cord stimulation as an option for patients with failed neck surgery syndrome.

Abstract
INTRODUCTION Spinal cord injury (SCI) is one of the most dreaded complications after spinal cord stimulation (SCS) implantation surgery. As a result, intraoperative neurophysiological monitoring (IONM) has been proposed to avoid accidental damage to nervous structures under anesthesia and confirm positioning for optimal stimulation. Our study uses a large administrative claims database to determine the 30-day risk of SCI after SCS implantation. METHODS This retrospective cohort study used the IBM MarketScan Commercial and Medicare Supplemental Databases from 2016 to 2019. Adult patients undergoing SCS surgical procedures with at least 90 days of follow-up, IONM use, the type of sedation used during the procedure, and subsequent SCI were identified using administrative codes. In addition, logistic regression was used to examine the relationship between various risk factors and subsequent SCI. RESULTS A total of 9676 patients underwent SCS surgery (64.7% percutaneous implants) during the study period. Nine hundred and forty-four (9.75%) patients underwent SCS implantation with IONM. Conscious sedation, Monitored Anesthesia Care anesthesia, and general anesthesia were used in patients with 0.9%, 60.2%, and 28.6%, respectively. Eighty-one (0.8%) patients developed SCI within 30 days after SCS implant surgery. The SCI rate was higher in the group that underwent IONM (2% vs 0.7%, p value <0.001) during the implantation procedure, reflecting the underlying risk. After adjustment for other factors, the OR of SCI is 2.39 (95% CI: 1.33 to 4.14, p value=0.002) times higher for those with IONM than those without IONM. CONCLUSIONS Increased SCI risk among patients with IONM likely reflects higher baseline risk, and further research is needed for risk mitigation.

Abstract
PURPOSE OF REVIEW Spinal cord stimulation has been increasing in influence as an option to regulate pain, especially in the chronic pain patient population. However, even with the numerous changes made to this technology since its inception, it is still prone to various complications such as hardware issues, neurological injury/epidural hematoma, infections, and other biological concerns. The purpose of this article is to thoroughly review and evaluate literature pertaining to the complications associated with percutaneous spinal cord stimulation. RECENT FINDINGS Lead migration is generally the most common complication of percutaneous spinal cord stimulation; however, recent utilization of various anchoring techniques has been discussed and experienced clinical success in decreasing the prevalence of lead migration and lead fractures. With newer high-frequency systems gaining traction to improve pain management and decrease complications as compared to traditional systems, rechargeable implantable pulse generators have been the preferred power source. However, recent findings may suggest that these rechargeable implantable pulse generators do not significantly increase battery life as much as was proposed. Intraoperative neuromonitoring has seen success in mitigating neurological injury postoperatively and may see more usage in the future through more testing. Though the occurrence of infection and biological complications, including dural puncture and skin erosion, has been less frequent over time, they should still be treated in accordance with established protocols. While many complications can arise following percutaneous spinal cord stimulator implantation, the procedure is less invasive than open implantation and has seen largely positive patient feedback. Hardware complications, the more common issues that can occur, rarely indicate a serious risk and can generally be remedied through reoperation. However, less common cases such as neurological injury, infections, and biological complications require prompt diagnosis to improve the condition of the patient and prevent significant damage.

Abstract
PURPOSE OF REVIEW Spinal cord stimulation (SCS) has been used for decades to alleviate chronic pain. A growing body of literature suggests that the procedure is not without risks. Understanding the risks of SCS implantation can help treating physicians formulate individualized care plans that promote patient safety and minimize risks. RECENT FINDINGS The overall complication rate associated with SCS has been reported to be 31.9 to 43%. The most common complication in the literature appears to be electrode migration. Other complications ranging in rates of occurrence include hematoma formation, infection, spinal cord injury, and cerebrospinal fluid (CSF) leak. Case reports of syrinx formation, foreign body reaction, and fibrosis have also been described. Our review shows that there are strategies available to reduce and prevent complications. In addition, close monitoring and early intervention may prevent some of the adverse neurological outcomes. Nevertheless, additional research regarding patient and procedural factors is necessary to improve the safety profile of this intervention.

Abstract
The most common complication of dorsal column spinal cord stimulator implantation is hardware migration. Spinal cord injury following paddle or percutaneous lead implant is rarely reported, with an overall incidence of 0.42%. This report describes a case of immediate post-operative incomplete paraplegia following implantation of one thoracic paddle electrode to address post-laminectomy pain syndrome. Despite emergent removal of the electrode, post-operative corticosteroids, and a course of inpatient rehabilitation, the patient discharged with persistent incomplete paraplegia. Although there is rare occurrence of spinal cord injury with spinal cord neuromodulation, it is important to recognize risk factors which may lead to similar devastating complications.
