ObjectiveSpinal cord stimulators (SCSs) are commonly implanted via a laminotomy or laminectomy. Revision surgery may be necessary in instances of hardware failure or loss of efficacy. It is uncommon for leads to have been initially misplaced in a suboptimal position and revision in these cases necessitates additional dissection for appropriate repositioning. Accordingly, there is concern with a more extensive revision for a potentially higher risk of associated complications. This study aims to describe a series of patients with failed paddle SCS electrodes due to misplacement who underwent revision and replacement.MethodsPatients who underwent SCS paddle replacement for misplaced paddles between 2021 and 2023 were identified. Medical charts were reviewed for demographic data, operative details, and incidence of complications.ResultsSixteen patients underwent thoracic SCS paddle revision and replacement. The mean age was 59.6 ± 12.6 years, with 11 females and 5 males. Misplaced paddles were too lateral (n = 12), too high (n = 2), or incompletely within the epidural space (n = 2). The mean duration from initial implantation to revision surgery was 44.8 ± 47.5 months. The mean operative duration was 126.1 ± 26.9 minutes and all patients required a "skip" laminectomy or laminotomy. No complications were encountered. The mean length of follow-up was 18.4 ± 7.3 months. Mean preoperative pain intensity was 7.9 ± 1.5 and at last follow-up was 3.6 ± 1.7 (P < 0.001). All but 1 patient continued to use their device in follow-up.ConclusionsThe revision and replacement of misplaced paddle SCS electrodes is a feasible and durable revision strategy, even in long-term implants with extensive scarring.Copyright © 2024 Elsevier Inc.
