This nationwide cohort study evaluated the association between ULI and future fall risk using Taiwan\u2019s National Health Insurance Research Database (2011\u20132019, follow-up through 2020). Methods: Adults aged \u2265 50 years with newly diagnosed ULI\u2014defined as fractures (clavicle, scapula, humerus, radius, ulna, hand), sprains, strains, or open wounds of the shoulder, arm, elbow, forearm, wrist, or hand\u2014were propensity score-matched 1:1 to controls by age, sex, and eight major comorbidities. Fall occurrence was identified by validated ICD codes, and Cox regression estimated hazard ratios (HRs) with 95% confidence intervals (CIs). Results: The cohort included 110,600 participants (mean follow-up 4.4 years). Fall incidence was 2.8 versus 1.6 per 1000 person-years in ULI versus control groups. Patients with ULI had 62% higher fall risk (adjusted HR 1.62, 95% CI: 1.43\u20131.84, p &lt; 0.001), corresponding to 1.2 additional falls per 1000 person-years. Kaplan\u2013Meier curves showed early divergence sustained throughout follow-up. Conclusions: ULI is independently associated with subsequent fall risk in older adults and may serve as a sentinel marker warranting fall-prevention strategies in clinical practice.<\/jats:p>","DOI":"10.3390\/jcm15135002","type":"journal-article","created":{"date-parts":[[2026,6,29]],"date-time":"2026-06-29T08:45:20Z","timestamp":1782722720000},"page":"5002","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Association Between Upper Limb Injury and Risk of Falls: A Nationwide Population-Based Cohort Study"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1664-3569","authenticated-orcid":false,"given":"Jhen-Jhen","family":"Fan","sequence":"first","affiliation":[{"name":"School of Medicine, Tzu Chi University, Hualien 970374, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen Chi","family":"Chan","sequence":"additional","affiliation":[{"name":"School of Medicine, Tzu Chi University, Hualien 970374, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8005-9958","authenticated-orcid":false,"given":"Jen-Hung","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Medical Research, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Hualien 970473, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pao","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Special Education, National Dong Hwa University, Hualien 974301, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ching-I","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Special Education, National Dong Hwa University, Hualien 974301, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6154-2167","authenticated-orcid":false,"given":"Kuang-Ting","family":"Yeh","sequence":"additional","affiliation":[{"name":"School of Medicine, Tzu Chi University, Hualien 970374, Taiwan"},{"name":"Department of Orthopedics, Hualien Tzu Chi Hospital, Buddhist Tzu Chi Medical Foundation, Hualien 970473, Taiwan"},{"name":"Institute of Medical Sciences, Tzu Chi University, Hualien 970374, Taiwan"},{"name":"Graduate Institute of Clinical Pharmacy, Tzu Chi University, Hualien 970374, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,26]]},"reference":[{"key":"ref_1","first-page":"121","article-title":"The fall and fracture in early stroke patients and the evaluation of influencing factors (1-year follow-up)","volume":"3","year":"2019","journal-title":"J.
