Introduction: bone mineral density (BMD) is a known risk factor for distal radius fractures. However,
there is no reported evidence of the association between low BMD and the complexity of the fracture
line. Objective: this study attempts to find the association of low BMD, as well as other risk factors,
with the AO (Arbeitsgemeinschaft für Osteosynthesefragen) classification of distal radius fracture.
Material and methods: 144 medical records of patients older than 44 years of age with information
on centripetal bone mineral density, smoking habit, body mass index and mechanism of trauma
were studied. Fractures were classified according to the AO 2018 system using tomography with
3D reconstruction. Results: it was found that there is a relationship between a low BMD with simple
fracture lines if they were due to a low energy mechanism (OR = 0.15; p = 0.009). However, the
high energy mechanism increases the risk of suffering complex fractures regardless of the degree
of BMD (OR = 5.56). Conclusion: there is a relationship between a low BMD and a simple line of
distal radius fracture according to the AO classification. However, a high-energy trauma mechanism
is a sufficient factor to generate a complex fracture line.
