- Abstract
Patients who sustain fragility fractures prior to total shoulder arthroplasty have significantly higher risk for bone health-related complications within 8 years of procedure. Identification of these high-risk patients with an emphasis on preoperative, intraoperative, and postoperative bone health optimization may help minimize these preventable complications., Purpose: As the population ages, more patients with osteoporosis are undergoing total shoulder arthroplasty (TSA), including those who have sustained a prior fragility fracture. Sustaining a fragility fracture before TSA has been associated with increased risk of short-term revision rates, periprosthetic fracture (PPF), and secondary fragility fractures but long-term implant survivorship in this patient population is unknown. Therefore, the purpose of this study was to characterize the association of prior fragility fractures with 8-year risks of revision TSA, periprosthetic fracture, and secondary fragility fracture., Methods: Patients aged 50 years and older who underwent TSA were identified in a large national database. Patients were stratified based on whether they sustained a fragility fracture within 3 years prior to TSA. Patients who had a prior fragility fracture (7631) were matched 1:1 to patients who did not based on age, gender, Charlson Comorbidity Index (CCI), smoking, obesity, diabetes mellitus, and alcohol use. Kaplan-Meier and Cox Proportional Hazards analyses were used to observe the cumulative incidences of all-cause revision, periprosthetic fracture, and secondary fragility fracture within 8 years of index surgery., Results: The 8-year cumulative incidence of revision TSA (5.7% vs. 4.1%), periprosthetic fracture (3.8% vs. 1.4%), and secondary fragility fracture (46.5% vs. 10.1%) were significantly higher for those who had a prior fragility fracture when compared to those who did not. On multivariable analysis, a prior fragility fracture was associated with higher risks of revision (hazard ratio [HR], 1.48; 95% confidence interval [CI], 1.24-1.74; p < 0.001), periprosthetic fracture (HR, 2.98; 95% CI, 2.18-4.07; p < 0.001) and secondary fragility fracture (HR, 8.39; 95% CI, 7.62-9.24; p < 0.001)., Conclusions: Prior fragility fracture was a significant risk factor for revision, periprosthetic fracture, and secondary fragility fracture within 8 years of primary TSA. Identification of these high-risk patients with an emphasis on preoperative and postoperative bone health optimization may help minimize these complications., Level of Evidence: III., (© 2024.
