The goal of this study was to assess long-term outcomes in obese versus nonobese patients after surgery for grade 1 spondylolisthesis.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>METHODS<\/jats:title>\n<jats:p>Patients who underwent surgery for grade 1 spondylolisthesis at the Quality Outcomes Database\u2019s 12 highest enrolling sites (SpineCORe group) were identified. Long-term (5-year) outcomes were compared for patients with BMI \u2265 35 versus BMI &lt; 35.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>In total, 608 patients (57.6% female) were included. Follow-up was 81% (excluding patients who had died) at 5 years. The BMI \u2265 35 cohort (130 patients, 21.4%) was compared to the BMI &lt; 35 cohort (478 patients, 78.6%). At baseline, patients with BMI \u2265 35 were more likely to be younger (58.5 \u00b1 11.4 vs 63.2 \u00b1 12.0 years old, p &lt; 0.001), to present with both back and leg pain (53.8% vs 37.0%, p = 0.002), and to require ambulation assistance (20.8% vs 9.2%, p &lt; 0.001). Furthermore, the cohort with BMI \u2265 35 had worse baseline patient-reported outcomes including visual analog scale (VAS) back (7.6 \u00b1 2.3 vs 6.5 \u00b1 2.8, p &lt; 0.001) and leg (7.1 \u00b1 2.6 vs 6.4 \u00b1 2.9, p = 0.031) pain, disability measured by the Oswestry Disability Index (ODI) (53.7 \u00b1 15.7 vs 44.8 \u00b1 17.0, p &lt; 0.001), and quality of life on EuroQol-5D (EQ-5D) questionnaire (0.47 \u00b1 0.22 vs 0.56 \u00b1 0.22, p &lt; 0.001). Patients with BMI \u2265 35 were more likely to undergo fusion (85.4% vs 74.7%, p = 0.01). There were no significant differences in 30- and 90-day readmission rates (p &gt; 0.05).<\/jats:p>\n<jats:p>Five years postoperatively, there were no differences in reoperation rates or the development of adjacent-segment disease for patients in either BMI &lt; 35 or \u2265 35 cohorts who underwent fusion (p &gt; 0.05). On multivariate analysis, BMI \u2265 35 was a significant risk factor for not achieving minimal clinically important differences (MCIDs) for VAS leg pain (OR 0.429, 95% CI 0.209\u20130.876, p = 0.020), but BMI \u2265 35 was not a predictor for achieving MCID for VAS back pain, ODI, or EQ-5D at 5 years postoperatively.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>Both obese and nonobese patients benefit from surgery for grade 1 spondylolisthesis. At the 5-year time point, patients with BMI \u2265 35 have similarly low reoperation rates and achieve rates of satisfaction and MCID for back pain (but not leg pain), disability (ODI), and quality of life (EQ-5D) that are similar to those in patients with a BMI &lt; 35.<\/jats:p>\n<\/jats:sec>","DOI":"10.3171\/2024.5.spine24125","type":"journal-article","created":{"date-parts":[[2024,9,14]],"date-time":"2024-09-14T05:27:42Z","timestamp":1726291662000},"page":"564-571","source":"Crossref","is-referenced-by-count":7,"title":["Do obese patients undergoing surgery for grade 1 spondylolisthesis have worse outcomes at 5 years\u2019 follow-up?
