Khan JM, Basques BA, Kunze KN, et al. - Via a retrospective cohort study carried out for patients who underwent open posterior lumbar spine fusion (PLSF) from 2011 to 2018, researchers contrasted clinical patient-reported outcomes and radiographic sagittal parameters between obese and non-obese patients after open PLSF. A total of 569 patients were involved of whom, 290 patients with BMI < 30 (non-obese) and 279 patients with BMI ≥ 30 (obese). A diagnosis of diabetes mellitus, and American Society of Anesthesiologists Physical Status Classification System of ≥ 3 was more likely in patients classified as obese. Significantly longer operative times was noted in obese patients vs non-obese patients. No variation in radiographic measurements, patient-reported outcomes, postoperative complications, or reoperations among groups was observed. In conclusion, significantly more comorbidities and longer operative time was noted in obese patients vs non-obese patients. Nevertheless, sagittal parameters, patient-reported outcomes, inpatient complications, length of hospital stay, and reoperations were comparable amongst groups. Provided these findings, open PLSF can be acknowledged as a safe and efficient in obese patients following thorough consideration of related comorbidities.
