Abstract

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To determine independent risk factors for sacral fracture after lumbosacral fusion. SUMMARY OF BACKGROUND DATA: Sacral fractures are an uncommon complication after lumbosacral fusion, with recent research suggesting that osteoporosis is an independent risk factor. However, there is a paucity of data regarding other potential risk factors. METHODS: This retrospective study (TriNetX) included adults (18 y or above) who underwent first-time lumbosacral fusion between 2005 and 2023, divided into 2 cohorts: the osteoporosis cohort and the no osteoporosis cohort. The primary outcome was the incidence of sacral fracture after lumbosacral fusion over 2 years, estimated using Kaplan-Meier analysis, with hazard ratios (HRs) estimated for each covariate using a multivariable Cox proportional hazards model (P
