Abstract
Objective
The purpose of this study was to evaluate the long term efficacy of spinal cord stimulation (SCS) for the neuropathic pain. We reviewed our experience with spinal cord stimulation.
Methods
Twenty-six neuropathic pain patients were identified who underwent spinal cord stimulation. Five patients were tried trial. All patients were referred for spinal cord stimulation from a multidisciplinary pain clinic having completed at least 6 months of conservative treatment with physical therapy, pain medications, epidural blocks, etc. The majority of patients were diagnosed with complex regional pain syndrome, followed in number by failed back surgery syndrome, spinal cord injury, cauda equina syndrome, etc. All paients were screemed with a tempoary electrode system in order to estabilish satisfactory relief of pain before internalization of permanent system. 21 (81%) proceeded to undergo permanent implantation pre- and postoperative pain levels were based on the administrations of visual analogue scale (VAS). A modifed outcome scale was used to compare the long-term efficacy of spinal cord stimulation.
Results
Visual analogue scale (VAS) decreased an average of 5.4 for patients undergoing specify SCS placement. Specify electordes exhibited good or excellent outcome in 100%. There was no mortality directly associated with surgery.
Conclusion
Spinal cord stimulation is a safe, useful, minimally invasive procedure for the treatment of intractable neuropathic pain.
Key Words: Spinal cord stimulation, Complex regional pain.
