We aimed to determine whether a combined DRF and distal ulna fracture (DRUF) predicts a worse patient-reported outcome, measured by the Disabilities of the Arm, Shoulder, and Hand (DASH) score, 1 year after injury.Methods:\u00a0This prospective registry-based cohort study included 5,536 adult patients with a DRF between 2003 and 2018. The 1-year DASH scores were recorded. All DRUFs were identified. Multivariable binary logistic regression assessed whether the presence of a distal ulna fracture predicted a 1-year DASH score &gt; 35, indicating severe upper-extremity symptoms.Results:\u00a0259 of 5,536 patients (4.7%) had a DRUF. Their mean age was 73 years (SD 15), and 86% were women. The median 1-year DASH score was higher in the combined fracture group compared with those with a DRF only (23, interquartile range [IQR] 5\u201345] vs 9, IQR 2\u201327, P &lt; 0.001). A DRUF increased the odds of a 1-year DASH &gt; 35 by 97% (OR 1.97, 95% confidence interval [CI] 1.40\u20132.75, P &lt; 0.001). Surgical fixation of the DRF in DRUF patients was associated with lower odds of a worse outcome (OR 0.44, CI 0.23\u20130.85, P = 0.02). Distal ulna fracture fixation did not affect 1-year DASH (P = 0.7).Conclusion:\u00a0The odds of having a DASH &gt; 35, indicating severe symptoms, almost doubled at 1 year in patients with a DRUF compared with those with a DRF only.<\/jats:p>","DOI":"10.2340\/17453674.2025.44352","type":"journal-article","created":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T10:29:45Z","timestamp":1755253785000},"source":"Crossref","is-referenced-by-count":5,"title":["Double trouble!
