They present with non-specific symptoms and can be occult on initial imaging making their diagnosis difficult, sometimes resulting in complications. Overlapping terminologies used to describe these fractures may hamper effective communication between the radiologist and the clinician. In this article, we review various atraumatic fractures of femur, terminologies used to describe them, their imaging findings and differential diagnosis. The article also describes the aetiology, pathophysiology and relevant biomechanics behind these fractures. An approach to atraumatic femoral fractures has been outlined.<\/jats:p>","DOI":"10.1259\/bjr.20201457","type":"journal-article","created":{"date-parts":[[2021,3,9]],"date-time":"2021-03-09T00:38:32Z","timestamp":1615250312000},"source":"Crossref","is-referenced-by-count":10,"title":["Atraumatic fractures of the femur"],"prefix":"10.1093","volume":"94","author":[{"given":"Ganesh","family":"Hedge","sequence":"first","affiliation":[{"name":"Department of Radiology, Royal Lancaster Infirmary , Lancaster , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siddharth","family":"Thaker","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Radiology, Leeds Teaching Hospitals , Leeds , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajesh","family":"Botchu","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Radiology, Royal Orthopaedic Hospital , Birmingham , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Fawcett","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Radiology, Leeds Teaching Hospitals , Leeds , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8292-9096","authenticated-orcid":false,"given":"Harun","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Musculoskeletal Radiology, Leeds Teaching Hospitals , Leeds , UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2021,3,18]]},"reference":[{"key":"2024050215481583100_b1","doi-asserted-by":"crossref","first-page":"2173","DOI":"10.1148\/rg.2018180073","article-title":"Imaging features and management of stress, atypical, and pathologic fractures","volume":"38","author":"Marshall","year":"2018","journal-title":"Radiographics"},{"key":"2024050215481583100_b2","doi-asserted-by":"crossref","first-page":"1001-4","DOI":"10.1001\/jama.1964.03060260029006","article-title":"Fatigue, insufficiency, and pathologic fractures","volume":"187","author":"Pentecost","year":"1964","journal-title":"JAMA"},{"key":"2024050215481583100_b3","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1148\/radiology.199.1.8633129","article-title":"Stress fractures","volume":"199","author":"Anderson","year":"1996","journal-title":"Radiology"},{"key":"2024050215481583100_b4","doi-asserted-by":"crossref","first-page":"349","DOI":"10.1007\/s00068-015-0530-z","article-title":"Fragility fractures of the sacrum: how to identify and when to treat surgically?","volume":"41","author":"Wagner","year":"2015","journal-title":"Eur J Trauma Emerg Surg"},{"key":"2024050215481583100_b5","doi-asserted-by":"crossref","first-page":"34","DOI":"10.2106\/JBJS.J.01915","article-title":"Pathologic fractures in children with acute Staphylococcus aureus osteomyelitis","volume":"94","author":"Belthur","year":"2012","journal-title":"J Bone Joint Surg Am"},{"key":"2024050215481583100_b6","doi-asserted-by":"crossref","first-page":"601","DOI":"10.2214\/AJR.17.18639","article-title":"Femoral neck stress injuries: analysis of 156 cases in a U.S. military population and proposal of a new MRI classification system","volume":"210","author":"Rohena-Quinquilla","year":"2018","journal-title":"AJR Am J Roentgenol"},{"key":"2024050215481583100_b7","first-page":"97","article-title":"Stress fracture of the pelvis and lower limbs including atypical femoral fractures\u2014a review.
