A multi-site review of second hip fractures across 6 Dublin teaching hospitals

Introduction Fragility hip fractures are common and costly. Secondary fracture prevention is a treatment goal following hip fracture; however, the number of those that proceed to fracture their contralateral hip in Ireland is unknown. There are plans to introduce a Fracture Liaison Service Database in Ireland which will aim to prevent secondary fractures. To establish a baseline figure for secondary hip fractures, the injury radiographs of 1284 patients from 6 teaching hospitals over a 1-year period were reviewed. Methods Irish Hip Fracture Datasheets and corresponding injury radiographs were reviewed locally for all hip fractures within each respective teaching hospital for a 1-year period (2019). Results A total of 8.7% of all fragility hip fractures across the 6 hospitals were secondary hip fractures (range 4.9–11.5%). 46% occurred within years 1 to 3 following index hip fracture. Forty-eight per cent of patients were started on bone protection medications following their second hip fracture. Discussion/Conclusion Approximately 1 in 11 hip fractures treated across the 6 teaching hospitals assessed in 2019 was a patient’s second hip fracture. We advocate for the widespread availability of Fracture Liaison Services to patients throughout Ireland to assist secondary fracture prevention.
