Day Case Lumbar Fusion Surgery
This article published in the journal Clin Orthop Surg examines the predictors of endplate fracture (EF) after oblique lumbar interbody fusion (OLIF) surgery. The study reviewed 104 patients who underwent OLIF between August 2019 and February 2022 and collected their demographic data, surgical details, and radiographic variables. The analysis revealed that factors such as sex, inferior endplate concave depth, disc wedge angle, lumbar lordosis, pelvic incidence, sagittal vertical axis, sacral slope, and specific lumbar levels were significantly related to EF. The authors concluded that OLIF in older Asian patients should be performed cautiously after considering the high possibility of EF and taking into account the identified predictive factors

ABSTRACT
BACKGROUND: Cage subsidence after oblique lumbar interbody fusion (OLIF) induces restenosis and adversely affects patient outcomes. Many studies have investigated the causes of subsidence, one of which is endplate fracture (EF). This study aimed to identify predictors of EF after OLIF.
METHODS: This retrospective study reviewed consecutive patients who underwent OLIF at a single institute between August 2019 and February 2022. A total of 104 patients were enrolled. The patients’ demographic data and surgical details were collected through chart reviews. Radiographic variables were measured. Related variables were also analyzed using binomial logistic regression, dividing each group into those with versus without EF.
RESULTS: EF occurred at 30 of 164 levels (18.3%), and the binary logistic analysis revealed that sex (odds ratio [OR]11.07), inferior endplate concave depth (OR, 1.95), disc wedge angle (OR, 1.22), lumbar lordosis (OR, 1.09), pelvic incidence (OR, 1.07), sagittal vertical axis (OR, 1.02), sacral slope (OR, 0.9), L3-4 level (OR, 0.005), and L4-5 level (OR, 0.004) were significantly related to EF.
S: OLIF in older Asian patients should be performed carefully after recognizing the high possibility of EF and confirming the factors that should be considered preoperatively.
