Secondary fracture rates and risk factors 1 year after a proximal femoral fracture under FLS.

Introduction: We aimed to investigate the secondary fracture rates and risk factors in patients with proximal femoral fractures using fracture liaison service (FLS) during the coronavirus disease (COVID)-19 pandemic.

Materials And Methods: In this multi-center prospective cohort study, patients with proximal femoral fractures who were treated surgically at three hospitals from April 2020 to March 2021 were included. Follow-up examinations at 6 and 12 months postoperatively were conducted to investigate the clinical data and ascertain whether osteoporosis treatment could be continued.
