Low-energy vertebral fractures requiring a fusion in the elderly associate higher mortality than high-energy injuries

Purpose: This study aims to analyze whether mortality in patients over 50 years of age requiring vertebral fusion for a thoracolumbar fracture depends on the injury mechanism (high or low energy), as well as to determine independent risk factors for mortality in this patient profile. Methods: Patients aged 50 or more years with thoracolumbar fractures who required vertebral fusion for this reason between 2008 and 2021 were included in the study. Survival was determined with the Kaplan-Meier method, and Cox regression analyses were used to determine mortality risk factors.研究目的：本研究旨在探讨因胸腰椎骨折接受脊柱融合术的50岁及以上患者的死亡率是否与损伤机制（高能量或低能量损伤）相关，并明确该类患者群体的死亡率独立危险因素。 研究方法：本研究纳入2008年至2021年间因胸腰椎骨折接受脊柱融合术的50岁及以上患者。采用卡普兰-迈耶法(Kaplan-Meier)计算生存率，通过考克斯回归(Cox)分析明确该人群死亡率的独立危险因素。
