IntroductionSpinal cord stimulation (SCS) is sometimes preferable in some refractory chronic lower back pain (LBP) pathologies. SCS involves an insertion of electrode leads into the epidural space in the prone position under local anesthesia, followed by neurostimulator implantation under local/general anesthesia. These continuous procedures can cause transient post-operative LBP exacerbation and to make temporary pockets that will store redundant leads in it with some risk of subcutaneous irritation and infection in addition to making extra incisions. We introduce a modified simpler method for SCS implantation, systematically designed to be performed only under local anesthesia in a decubitus, non-prone position.Materials And MethodsAn 81-year-old patient with FBSS was treated. A physician was able to insert SCS leads with ease while the patient was in a decubitus position. The patient was comfortable, under totally local anesthesia, and the procedure produced no extra subcutaneous pockets.ResultThe patient felt almost no LBP and reported no pain exacerbation during the operation. The SCS installation provided the patient with great improvement in both her lower back (NRS from 8 to 0-1) and leg (from 7 to 2) pain with a great improvement in her daily life activities. No adverse events were observed during the perioperative period.ConclusionThe modified SCS insertion method enabled us to achieve both intraoperative pain relief and complete SCS implantation in a minimally invasive manner.
