Incidence and Mortality of Osteoporotic Sacral Insufficiency Fractures: A Retrospective Singlecentre Study

Abstract

Objective: The incidence of osteoporosis increases with the ageing of the world population. In recent years, sacral insufficiency fractures (SIF) have become more prevalent due to the increase in life expectancy of the elderly population. The aim of this study was to investigate the incidence and the mortality rates of SIF in elderly patients with osteoporosis. Materials and Methods: The records of patients admitted to our hospital between January 2011 and May 2018 were examined. Medical records, radiological images and reports of 245 patients over 65 years of age who had undergone pelvic computed tomography (CT) or magnetic resonance imaging (MRI) for any reason were retrospectively reviewed. Twenty-six patients (three male, 23 female) over 65 years of age who were proven to have osteoporosis with bone mineral densitometry (BMD) values at the time of diagnosis were included in the study. Results: The mean age at the time of diagnosis was 80,5. MRI was used for diagnosis in 20 patients and CT in six patients. The mean value of BMD was found to be-3.62. The most common type of fracture was B1. Surgery was performed in four patients and conservative treatment in 22 patients. Conclusion: Increased risk of fractures due to osteoporosis also increases the risk of SIF. In our study, the incidence of fractures of sacral insufficiency was found to be 12.44% and 5-year mortality was 26.9%.
