Use of spinal cord stimulation in managing neuropathic foot pain: A case series study

Abstract

Background/ Aim:In cases of complex regional pain syndrome where conservative treatment is unsuccessful in controlling neuropathic foot pain spinal cord stimulation may be considered. To our knowledge there have been no such cases reported in the foot & ankle literature. The aim of the study was to establish useful information that may supplement our understanding of this complex multifactorial problem and help to inform future management of similar cases. Materials and method:A case series study was undertaken to investigate the use of spinal cord stimulation in the management of neuropathic foot pain using five cases with complex regional pain syndrome (type I).Results:Reduced pain following spinal cord stimulation was reported. The interval between diagnosis and commencement of spinal cord stimulation was variable between cases and maybe responsible for differing levels and timing of pain relief experienced.Conclusion:Careful preoperative diagnosis, robust patient selection and close postoperative monitoring are vital for a successful outcome. The small sample size and potential for bias, limit the generalizability to a larger population. A larger study is therefore indicated to expand upon preliminary findings.
