BACKGROUND: Fragility fractures are often the initial clinical presentation of osteoporosis. Patients who have a history of fragility fractures undergoing total hip arthroplasty (THA) have an increased risk of 2-year postoperative complications. However, the association of recent fragility fractures with complications beyond 2 years following THA remains unknown. The purpose of this study was to characterize the association of prior fragility fractures with 8-year risks of revision THA, periprosthetic fracture (PPF), and secondary fragility fracture.
METHODS: Patients aged 50 years and more who underwent THA for osteoarthritis were identified in a large national database. Patients were stratified based on whether they sustained a fragility fracture within 3 years prior to THA. There were 18,529 patients who had a prior fragility fracture and 408,753 who did not have a prior fragility fracture. Demographics and comorbidities were collected. Kaplan-Meier and Cox Proportional Hazards analyses were used to observe the cumulative incidences of all-cause revision, PPF, and secondary fragility fracture within 8 years of index surgery.
RESULTS: Patients who had recent fragility fracture had significantly higher risks of revision THA (Hazard Ratio [HR] 1.7; P < .001), PPF (HR 2.2; P < .001), and secondary fragility fracture (HR 4.9; P < .001).
CONCLUSION: Prior fragility fracture was shown to be a significant risk factor for revision THA, PPF, and secondary fragility fracture within 8 years of THA. Identification of these high-risk patients with an emphasis on preoperative and postoperative bone health optimization may help minimize these complications.
