Introduction: Spinal cord stimulation (SCS) is a form of chronic pain treatment that has been shown to be effective in patients who have responded poorly to other therapies. The current indications for SCS devices are very varied. The aim of our study is to analyze the diagnostic indications of SCS therapy during the last 5 years in our hospital, to know the most frequent causes of pain for the indication of the implant of the device and what percentage of improvement patients present, as well as to study the relationship with gender and age.
Material and methods: This is an observational, descriptive, retrospective study. The patients were identified from the surgical activity register of the Pain Unit of the General Hospital of Valencia.
Results: The final number of patients included was 179. The Failed back surgery syndrome (FBSS) was the diagnostic indication in 112 patients (62.57 %). The mean percentage of improvement described by the patients after the SCS implant was 47.99 ± 27.3 %. There were no differences in the improvement with respect to age or gender.
Discussion: In spite of the variability of diagnoses in which this therapy may be indicated, it is noteworthy that in more than half of the cases the indication is by FBSS.


Introducción: La neuroestimulación medular (NM) es una forma de tratamiento del dolor crónico que ha demostrado su efectividad en pacientes que han respondido mal a otras terapias. Las indicaciones actuales para los dispositivos de NM son muy variadas. El objetivo de nuestro estudio es analizar las indicaciones diagnósticas de la terapia con NM durante los últimos 5 años en nuestro hospital, conocer cuáles son las causas de dolor más frecuentes para la indicación del implante del dispositivo y qué porcentaje de mejoría presentan los pacientes, así como estudiar la relación con el género y la edad.
Material y métodos: Se trata de un estudio observacional, descriptivo y retrospectivo. Los pacientes fueron identificados desde el registro de actividad quirúrgica de la Unidad del Dolor del Hospital General de Valencia.
Resultados: El número final de pacientes incluidos fue de 179. El síndrome de cirugía fallida de espalda (SCFE) fue la indicación diagnóstica en 112 pacientes (62,57 %). La media del porcentaje de mejoría descrita por los pacientes tras el implante del NM fue de 47,99 ± 27,3 %. No se observaron diferencias en la mejoría respecto a la edad o el género.
Discusión: A pesar de la variabilidad de diagnósticos en los que puede estar indicada esta terapia, es destacable que en más de la mitad de los casos la indicación es por SCFE.
