This study examines the effects of spine surgery on patient weight and finds that overweight and obese patients have higher odds of clinically significant weight loss after lumbar spine surgery compared to non-obese patients. The study highlights the importance of weight management in obese patients undergoing spine surgery.
-OBJECTIVE: Obesity is a major health care concern in the United States and is associated with high rates of postoperative complications after spine surgery. Obese patients assert that weight reduction is not possible unless spine surgery first relieves their pain and concomitant immobility. We describe the post-spine surgery effects on patient weight, with an emphasis on obesity.-METHODS: PubMed, EMBASE, Scopus, Web of Science, and Cochrane da-tabases were systematically searched according to the PRISMA guidelines. The search included indexed terms and text words from database inception to the date of the search (15 April 2022). Studies chosen for inclusion had to have data reporting on pre-and postoperative patient weight after spine surgery. Data and estimates were pooled using the Mantel-Haenszel method for random-effects meta-analysis.-RESULTS: Eight articles encompassing 7 retrospective and 1 prospective cohort were identified. A random effects model analysis demonstrated that overweight and obese patients (body mass index [BMI], >25 kg/m2) had increased odds of clinically significant weight loss after lumbar spine surgery compared with non-obese patients (odds ratio, 1.63; 95% confidence interval, 1.43e1.86, P < 0.0001). There was no significant difference in the raw weight change between BMI categories (mean difference, L0.67 kg, 95% confidence interval, L4.71 to 3.37 kg, P [ 0.7463).-CONCLUSIONS: Compared with non-obese patients (BMI, <25 kg/m2), over-weight and obese patients have higher odds of clinically significant weight loss after lumbar spine surgery. No difference in pre-operative and post-operative weight was found, although statistical power was lacking in this analysis. Randomized controlled trials and additional prospective cohorts are needed to further validate these findings.
