© 2015 International Neuromodulation Society. The following study is designed to compare two implant techniques for a single surgeon by assessing differences in complications rates in the two cohort groups. As the use of SCS continues to grow, research into the causes of and risk factors for SCS-related complications is paramount to decrease complication rates in the future.Ĭomplications neuropathic pain outcomes retrospective study spinal cord stimulation. However, the surgical revision and explant rates are relatively high. It is a minimally invasive procedure, safe, and with good long-term outcomes. SCS is an effective treatment for chronic noncancer pain. The most common reason for explant was loss of therapeutic effect (41.1%). The revision and explant rates were 23.9% each. The complication rate was 34.6%, with the hardware related being the most common reason, comprising 74.1% of all complications. Two hundred thirty-four patients were implanted with an implant-to-trial ratio of 67-86% across various chronic pain entities (postlaminectomy syndrome, complex regional pain syndrome, small-fiber peripheral neuropathy, abdominal/pelvic pain, nonsurgical candidates with lumbosacral neuropathy, and neuropathic pain not otherwise specified), with the exception of nonsurgical candidates with lumbosacral neuropathy who had an implant ratio of 43%. This is a retrospective study of all patients who underwent a percutaneous spinal cord stimulation trial followed by implant in an academic Pain Medicine division by four practitioners from 2007 to 2013, with follow-up data through April 2014.Ī total of 345 patients were considered candidates for dorsal column stimulation and underwent a trial. The expected positioning of SCSs based on the location of pain, the types of electrodes (percutaneous vs surgical paddle), and the types of electrode arrays and the potential complications have not been described to date in the. The study aims to evaluate the long-term implant survival and complications of spinal cord stimulation (SCS) leading to surgical revision or explant in patients treated for chronic noncancer pain. Implantation of a spinal cord stimulator (SCS) is one option for pain control in individuals with chronic lumbosacral radicular or axial lumbar pain.
