Metaphyseal comminution in patients with DRFs may indicate severe osteoporosis and heightened bone fragility. However, its relationship with the risk of secondary fragility fractures remains unclear. This study aimed to evaluate the incidence of secondary fractures in patients with DRFs involving metaphyseal comminution and assess the effectiveness of osteoporosis treatment in reducing this risk.</p><p><strong>Methods: </strong>In this retrospective cohort study, 134 patients aged ≥ 50 years underwent DRF surgery at a single institution from July 2018 to December 2022. The patients were allocated into groups by the presence (n = 45) or absence (n = 89) of metaphyseal comminution. The primary outcome was secondary fracture incidence. A multivariate Cox model was used, adjusting for age, sex, body mass index, bone mineral density, osteoporosis treatment type, and dementia.</p><p><strong>Results: </strong>Secondary fractures were significantly more frequent in the comminution group (17.8%) than in the non-comminution group (3.4%) (p = 0.004).
