Abstract:

Objective To investigate the effect of sarcopenia on mortality after osteoporotic thoracolumbar compression fracture（OTLCF）in elderly patients. Methods A total of 114 elderly patients who met the inclusion and exclusion criteria were included from February 2014 to February 2017. The patients were divided into sarcope⁃ nia group and non⁃sarcopenia group according to the SMI diagnosis cut⁃off value. Kaplan Meier was used to analyze the survival curves of the two groups of patients，and the chi⁃square test to compare the survival rate between the two groups 12，24 and 36 months after the surgery. The Cox proportional hazards model was used to analyze the effects of multivariate factors such as sarcopenia，thoracic or lumbar fractures，age，gender，and American Society of Anesthetists（ASA）grade on postoperative mortality of OTLCF. Results There was statistical difference between the 36⁃month mortality rates（P = 0.016）. Patients with sarcopenia and patients with higher ASA grade had a higher mortality rate 36 months after the surgery. Conclusion Sarcopenia increases the risk of long ⁃term（36 months）
