This narrative review synthesizes current evidence on the prevalence, pathophysiology, and clinical consequences of malnutrition in hip fracture patients, along with diagnostic tools and nutritional interventions. Methods: A literature search of studies from 2000 to 2025 identified consistent associations between malnutrition\u2014defined using tools such as the Mini Nutritional Assessment (MNA), Geriatric Nutritional Risk Index (GNRI), and serum albumin levels\u2014and increased risks of postoperative complications, prolonged hospital stays, functional decline, and mortality. Pathophysiological mechanisms include sarcopenia, systemic inflammation, and impaired bone metabolism. Results: Notably, malnutrition is associated with fracture type, with low lean body mass and poor nutritional status correlating with intracapsular femoral neck fractures. Conclusions: Interventional studies demonstrate that oral nutritional supplementation (ONS) reduces complications and improves biochemical parameters but shows mixed effects on long-term mortality and function. The findings support routine nutritional screening and early intervention in older hip fracture patients to improve outcomes and reduce the healthcare burden.<\/jats:p>","DOI":"10.3390\/jcm14165662","type":"journal-article","created":{"date-parts":[[2025,8,11]],"date-time":"2025-08-11T09:59:13Z","timestamp":1754906353000},"page":"5662","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Malnutrition in Older Hip Fracture Patients: Prevalence, Pathophysiology, Clinical Outcomes, and Treatment\u2014A Systematic Review"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1096-4041","authenticated-orcid":false,"given":"Geert","family":"Meermans","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, Bravis Hospital, Boerhaavelaan 25, 4708 AE Roosendaal, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0711-0459","authenticated-orcid":false,"given":"Jeroen C.","family":"van Egmond","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, Bravis Hospital, Boerhaavelaan 25, 4708 AE Roosendaal, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1236","DOI":"10.1093\/gerona\/glt092","article-title":"Epidemiology of Fracture Risk with Advancing Age","volume":"68","author":"Ensrud","year":"2013","journal-title":"J.
