Abordaje mínimamente invasivo para hernias de disco extraforaminales: indicaciones, consideraciones quirúrgicas y resultados clínicos

Abstract

Introduction: Extraforaminal disc herniations represents 0.3-11.3% of every herniated lumbar discs. A variety of surgical procedures may be used for the treatment of this pathology.
Objective: The aim of this study is to present 5 cases of extraforaminal herniated discs treated via a minimally invasive spine surgery using tubular retractors, to describe the surgical technique and to analyze the literature on this subject.
Pacients and method: 5 patients who did not get better with conservative treatment were operated using minimally invasive tubular retractors between January 2018 and February 2019. Demographic variables and intraoperative data were analyzed. Clinical outcomes was evaluated using the Analog Visual Scale (VAS).
Results: Five patients who presented neurological deficit and low back pain were operated. Every patients was discharged before 24 hours postoperative. VAS significantly decrease comparing pre and postoperative (p=0.038). No cerebrospinal fluid leaks or infections were recorded.
Conclusion: The use of minimally invasive tubular retractors is an effective technique for treating extraforaminal herniated discs.
