AB  - PURPOSE: The purpose of this study is to compare clinical patient-reported 
      outcomes and radiographic sagittal parameters between obese and non-obese 
      patients following open posterior lumbar spine fusion (PLSF). METHODS: A 
      retrospective cohort study was conducted for patients who underwent open PLSF 
      from 2011 to 2018. Patients were classified as obese as per Center for Disease 
      Control and Prevention guidelines if their body mass index (BMI) >/= 30 kg/m(2). 
      Preoperative and final visual analog scale (VAS) back pain, VAS leg pain, and 
      Oswestry Disability Index (ODI) were obtained for both obese and non-obese 
      groups. Achievement of minimal clinically important difference was evaluated. 
      Preoperative, immediate postoperative, and final lumbar plain radiographs were 
      assessed to measure spinopelvic parameters. Additionally, postoperative 
      complication measures were collected. RESULTS: A total of 569 patients were 
      included; 290 (50.97%) patients with BMI < 30 (non-obese) and 279 (49.03%) 
      patients with BMI >/= 30 (obese). Patients classified as obese were more likely to 
      have a diagnosis of diabetes mellitus (p < 0.001), and American Society of 
      Anesthesiologists Physical Status Classification System of >/= 3 (p < 0.001). Obese 
      patients had significantly longer operative times (p < 0.001) compared to 
      non-obese patients. There was no difference in radiographic measurements, 
      patient-reported outcomes, postoperative complications, or reoperations between 
      groups. CONCLUSION: Obese patients had significantly more comorbidities and 
      longer operative time compared to non-obese patients. However, sagittal 
      parameters, patient-reported outcomes, inpatient complications, length of 
      hospital stay, and reoperations were similar between groups. Given these 
      findings, open PLSF can be considered safe and effective in obese patients after 
      thorough consideration of related comorbidities. These slides can be retrieved
