Day Case Lumbar Fusion Surgery
This article discusses the relationship between obesity and surgical outcomes in patients undergoing short-segment open posterior lumbar fusion (PLF). The researchers aimed to determine the impact of Body Mass Index (BMI) on pseudarthrosis, Adjacent Segment Pathology (ASP), and the need for reoperation. A retrospective study was conducted on patients who underwent 1-, 2-, or 3-level PLF surgery between 2010 and 2020. The study included 363 patients, and the results showed that BMI was significantly lower in patients who developed pseudarthrosis compared to those who did not. However, BMI did not significantly differ in patients who developed ASP or underwent reoperation. Furthermore, multivariate regression analysis did not identify any significant predictors for pseudarthrosis, ASP, or reoperation. In conclusion, obese patients undergoing short-segment PLF had similar outcomes in terms of pseudarthrosis, ASP, and reoperation

ABSTRACT
OBJECTIVES: Obesity is a growing epidemic in the United States. While many adverse effects of obesity on surgical outcome are well studied, a direct correlation between obesity, pseudarthrosis and adjacent segment pathology is not well defined. In this study we aimed to identify the effect of Body Mass Index (BMI) on pseudarthrosis, Adjacent Segment Pathology (ASP) and reoperation after short-segment (1-3 levels) open posterior lumbar fusion (PLF).
METHODS: This is a retrospective study of patients with degenerative spine pathologies who underwent 1-, 2-, or 3-level PLF surgery between 2010 and 2020. The relevant medical and imaging records were reviewed, and the following variables were recorded: age, gender, body mass index (BMI), smoking status, surgical details, follow-up length, need for reoperation, indication for reoperation (pseudarthrosis or occurrence of ASP).
RESULTS: 363 patients were included in our study. 25 patients (6.9%) developed pseudarthrosis, 109 (30%) developed ASP and 104 patients (28.7%) underwent re-operation for either of these reasons. BMI was significantly less in those who developed pseudarthrosis compared to those who did not (28.6±5.5 vs. 31.2±6.2, respectively; p = 0.04). BMI was not significantly different in those who developed ASP or underwent re-operation compared to those who did not (p=0.06 and 0.08, respectively). Multivariate regression analysis showed none of the variables in the model (age, gender, tobacco use, BMI, and its classes) significantly predicted pseudarthrosis, ASP or re-operation (p > 0.1 for all variables).
CONCLUSION: Obese patients undergoing short-segment open PLF have comparable results in terms of pseudarthrosis, ASP, and re-operation.
