1, 2 Each year in the US, approximately 900 000 patients undergo spine surgery, with the incidence of failed back surgery syndrome, also called postlaminectomy syndrome (PLS), being around 19% for laminectomy and 46% for fusion. Low back pain (LBP) is the leading cause of disability worldwide, with point and 1-month prevalence rates of 12% and 23%, respectively. White patients were significantly more likely to be diagnosed with PLS (ie, underwent surgery) (90.4% vs 85.2% difference, 5.2% P < .001) and receive an SCS (93.7% vs 90.3% difference, 3.4% P < .001) than patients of other racial identities.Ĭonclusions and Relevance These findings suggest that under real-life conditions, SCS was associated with small, clinically questionable associations with opioid discontinuation and not starting opioids in the context of PLS. In multivariable analysis, SCS was associated with an increased likelihood of not being on opioids in both opioid-naive (adjusted odds ratio, 0.90 P < .001) and LOT patients (adjusted OR, 0.93 P = .02). In opioid-naive patients, SCS was associated with a small decreased likelihood of patients subsequently receiving LOT (7.6% vs 7.0% difference, −0.6% P = .003). In the 12-month study period, similar proportions in the SCS and no-SCS groups receiving baseline LOT remained on LOT (70.3% vs 69.2%, respectively P = .10). Compared with those who did not receive an SCS, individuals who received an SCS were more likely to be using opioids preimplantation (mean prescriptions: 4.3 vs 4.1 P < .001) but less likely to be using opioids after SCS implantation (mean prescriptions: 3.8 vs 4.0 P = .006). Among those reporting racial identify (37.0% ), 9.3% (18 971 patients) were African American, 0.3% (648 patients) were Asian, and 90.4% (185 139 patients) were White. The median (IQR) patient age was 60 (51-69) years 305 802 patients (55.3%) were female. Results Among 552 937 eligible patients treated between December 2015 and May 2021, 26 179 with PLS received an SCS implant. Opioid-naive patients were defined as those receiving at most 2 opioid prescriptions per year, and patients on LOT were those receiving at least 6 opioid prescriptions per year. Main Outcomes and Measures The main outcome was cessation of opioid use among patients receiving LOT or abstinence from opioids among opioid-naive patients. Statistical analysis was performed from June to December 2021. Patients were stratified according to baseline opioid use (opioid-naive or receiving LOT) and subsequent opioid therapy over the 12-month period ranging from 3 to 15 months post-SCS implantation or post-PLS index date. Objective To determine the association between SCS and long-term opioid therapy (LOT) for PLS.ĭesign, Setting, and Participants In this cohort study, adults with PLS were identified using the TriNetx Diamond Network and separated based on whether they underwent SCS. This has led to an increased emphasis on objective outcome measures such as opioid prescribing. Importance The results of studies evaluating spinal cord stimulation (SCS) for postlaminectomy syndrome (PLS) have yielded mixed results.
