  abstract     = {{Introduction:<br/>Combined distal radius and distal metaphyseal ulna fractures (DRUFs) predominantly affect elderly women and remain relatively understudied, likely due to their low incidence. Approximately 5% of all distal radius fractures (DRFs) involve a concomitant distal ulna fracture (excluding ulnar styloid fractures). Prior research has shown that DRUFs are associated with poorer patient-reported outcomes, with a twofold increased odds of a poor 1-year result (DASH &gt;35) compared with isolated DRFs. Existing literature suggests that no standardized treatment approach exists and that surgical fixation may be challenging due to osteoporosis. Distal radius fractures are well established as one of the most common fragility fractures. However, because the DRUF subgroup is so poorly characterized, the true prevalence and severity of osteoporosis in these patients remains unknown.<br/><br/>Aim:<br/>To test our hypothesis that patients with DRUFs have a higher prevalence and greater severity of osteoporosis compared with patients with isolated distal radius fractures.<br/><br/>Methods:<br/>A cohort of 200 DRUF patients was identified from a local quality registry of wrist fractures (patients registered between 2003 and 2018). From the same registry, 200 age- and sex-matched controls with isolated DRFs were randomly selected. For all patients, we determined whether a DXA scan had been performed within 365 days of the fracture date.<br/><br/>Results:<br/>Because of matching, each group consisted of 25 men and 175 women, with no difference in mean age between groups. DXA data were available for 45 patients in the DRUF group (1 man; mean age 69 years, SD 9) and 40 patients in the DRF-only group (5 men; mean age 68 years, SD 9). There were no significant differences in mean age or sex distribution among those who completed DXA.<br/>Comparing patients with available DXA results, mean BMD was significantly lower in the DRUF group (mean difference –0.74, SD 0.23; 95% CI –1.20 to –0.28; P = 0.002). Osteoporosis (T-score ≤ –2.5) was present in 32 of 45 DRUF patients (71%) compared with 12 of 40 DRF-only patients (30%) (P &lt; 0.001).<br/><br/>Conclusion:<br/>Patients with DRUFs demonstrated both a significantly higher prevalence of osteoporosis and more severe reductions in bone mineral density compared with patients sustaining isolated distal radius fractures. These findings suggest that underlying osteoporosis may be a key contributor to the injury pattern in DRUFs and should be actively considered in clinical evaluation and management.<br/>}},
