Effects of postoperative osteoporosis treatment on subsequent fracture and the 5-year survival rates after hemiarthroplasty for hip fracture

Summary: According to the literature, only 20–30% of patients are screened for osteoporosis after a hip fracture. Osteoporosis treatment may have a potential protective effect on the 5-year mortality rate. Our results demonstrated that 5-year survival is higher in patients who received osteoporosis treatment after hemiarthroplasty for hip fracture compared with those who did not. Purpose: This study aims to investigate the status of osteoporosis treatment in patients who underwent hemiarthroplasty for an osteoporotic hip fracture and to compare subsequent fractures and the 5-year survival rates of these patients with those who did not receive the osteoporosis treatment. Methods: Patients > 65 years of age who underwent hemiarthroplasty for an osteoporotic hip fracture were included in this retrospective multicenter study. Patients who died within 12 months postoperative, who were lost to follow-up, and those with malignancy and secondary osteoporosis were excluded. Group I comprised patients who had no postoperative osteoporosis screening and treatment, and Group II comprised those who received the screening and treatment. Results: A total of 460 of 562 patients (82%) did not receive osteoporosis treatment after hip fracture. No significant difference was observed between the groups in terms of subsequent fracture numbers and fracture sites (p = 0.296 and 0.240, respectively). Mean 5-year survival rate was significantly higher in Group II (p = 0.002). Conclusions: According to our results, elderly patients who underwent hemiarthroplasty for an osteoporotic hip fracture were not commonly screened or treated for osteoporosis. Our results demonstrated no significant difference between the groups in terms of subsequent fracture. However, we observed a significant high 5-year survival rate among patients who received the osteoporosis treatment. © 2019, International Osteoporosis Foundation and National Osteoporosis Foundation.
