Objective: To describe the experience of the Neurosurgery Section of the Universidad [Blinded] in the management of complex regional pain syndrome (CRPS) through stimulation of the posterior cords of the spinal cord (ECPME).Materials and Methods: The medical records of patients with CRPS treated with ECPME between 2018 and 2020 were reviewed.A form was applied that evaluated their socio-demographic characteristics, triggering event of the condition, time of evolution of the disease and pre-surgery treatment modalities, surgical intervention performed, pre-and post-operative visual analog scale (VAS), follow-up time, and pre-and post-surgical functionality.Results: We obtained results from 3 women and 2 men.Four of them suffered appendiceal fractures or joint sprain, and 1 patient had a complex brachial plexus injury.There had been at least 1 year of symptoms and they had aggressive first, second and third line pharmacological, non-pharmacological and interventional management before being taken to an ECPM performed at the cervical or dorsal level.There was a 60-90% decrease in pain on the VAS in a follow-up between 1-3 years, with improvement in functionality.Conclusions: The CRPS treatment paradigm includes non-invasive and invasive measures, with ECPME playing a leading role in many refractory cases, with acceptable and persistent symptomatic improvement.A 36% decrease in pain has been previously reported in other studies, a figure lower than that of this series of cases, where the results are superior in relation to the decrease in pain according to the VAS.
