Materials and Methods: We retrospectively analyzed 107 patients aged 65 and older with proximal femur fractures (PFFs) who underwent surgery at D\u00fczce University Medical Faculty between January 2010 and December 2022. High-energy fractures, pathological fractures, and patients with a history of old fractures were excluded. Results: The study included 66 females (61.7%) and 41 males (38.3%), with a mean age of 83.76 years. The mean interval between two fractures was 28.3 months. There was no statistical difference between the localization of the first and second fractures (p = 0.107). However, there was a significant difference in the first PFF localizations of patients living in rural areas (p = 0.023). Patients with heart failure, respiratory failure, osteoporosis, and cognitive impairment had shorter intervals between fractures (p &lt; 0.001). Conclusions: This study shows that age, female gender, place of residence, comorbid diseases, and whether physical therapy is received after the first fracture are significant risk factors for a second hip fracture in patients over 65 years of age.<\/jats:p>","DOI":"10.3390\/medicina60060928","type":"journal-article","created":{"date-parts":[[2024,6,3]],"date-time":"2024-06-03T12:19:46Z","timestamp":1717417186000},"page":"928","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The Characteristics and Outcomes of Contralateral Non-Concurrent Hip Fractures: A Retrospective Study in Geriatric Patients"],"prefix":"10.3390","volume":"60","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2651-8003","authenticated-orcid":false,"given":"S\u00f6nmez","family":"Sa\u011flam","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, Duzce University, 81620 Duzce, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet","family":"Ar\u0131can","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, Duzce University, 81620 Duzce, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6719-3666","authenticated-orcid":false,"given":"Zekeriya Okan","family":"Karaduman","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, Duzce University, 81620 Duzce, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9405-2367","authenticated-orcid":false,"given":"M\u00fccahid Osman","family":"Y\u00fccel","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, Duzce University, 81620 Duzce, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erdem","family":"De\u011firmenci","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, Duzce University, 81620 Duzce, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veysel","family":"Uluda\u011f","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Faculty of Medicine, Duzce University, 81620 Duzce, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"330","DOI":"10.1302\/0301-620X.73B2.2005167","article-title":"Fixation of intertrochanteric fractures of the femur.
