The Prevalence of Osteoporosis in Patients Older than 50 Years with Distal Radius Fractures in an Institutional Registry of 2,572 Patients in Singapore

Abstract

Background: The distal radius is one of the common sites for fragility fractures. A fracture of the distal radius in the elderly is often associated with low bone mineral density (BMD). It is an early predictor of osteoporosis and increased risk of subsequent fragility fractures of the hip and the spine with greater morbidity. Osteoporosis is becoming an increasing cause for concern in the elderly population. The aim of this study is to determine the prevalence of osteoporosis in patients aged 50 years and above with distal radius fractures in our local population. Methods: This is a retrospective study of all patients aged 50 years and above who were treated for a distal radius fracture at our institution over a 4-year period. Data regarding gender, mechanism of injury (low or high energy), and outcome of BMD scans were collected. The data were analyzed to look at the prevalence of osteoporosis and osteopenia and the relation amongst BMD, gender, and the mechanism of injury. Results: About 2,572 patients aged 50 years and above were treated at our institution over a 4-year period from 2013 to 2016. The average age of the patients was 67.7 years old and 1,938 (75.3%) were women. A total of 1,034 patients had BMD scans and of these 56.0% had osteoporosis and 37.4% had osteopenia. There was no correlation between the prevalence of osteoporosis and gender or the mechanism of injury. Conclusions: The prevalence of osteoporosis in patients aged 50 and above with distal radius fractures is a significant cause for concern in Singapore. Routine assessment for osteoporosis is recommended for all patients above 50 years old with distal radius fractures. Level of Evidence: Level III (Therapeutic).
