We investigated their prevalence and performed a statistical analysis to support their congenital origin. Their localization was mapped to show their exact site of occurrence. We evaluated anteroposterior and lateral X\u2010ray images of 2413 elbows in a Central European population from which a group of accessory bony structures was selected. Their character was evaluated, and accessory bones were identified. We used logistic regression to evaluate the potential relationship between the occurrence of accessory bones, the age of patients, and the occurrence of calcar olecrani. The prevalence of accessory bones of the elbow in the sample was 0.77%. Our results did not show a statistically significant relationship with the occurrence of calcar olecrani or with the age of patients. The most common type was os subepicondylare mediale (type V) in 0.46%, which was located distal to the medial epicondyle of the humerus, followed by os subepicondylare laterale (type III; 0.21%), situated laterally to the lateral epicondyle of the humerus. In comparison with previous reports, os sesamoideum mediale (type IV) was located more distally. Our data suggest that congenital accessory bones are a rare entity. Knowledge of their exact localization should be considered during diagnosis of avulsion fractures and other unclear diagnoses including accessory bony structures in the elbow region.<\/jats:p>","DOI":"10.1111\/joa.13233","type":"journal-article","created":{"date-parts":[[2020,8,25]],"date-time":"2020-08-25T06:21:48Z","timestamp":1598336508000},"page":"618-622","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Accessory bones of the elbow: Prevalence, localization and modified classification"],"prefix":"10.1111","volume":"237","author":[{"given":"Vojt\u011bch","family":"Kunc","sequence":"first","affiliation":[{"name":"Department of Anatomy Second Faculty of Medicine Charles University Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vladim\u00edr","family":"Kunc","sequence":"additional","affiliation":[{"name":"Department of Computer Science Czech Technical University Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vojt\u011bch","family":"\u010cern\u00fd","sequence":"additional","affiliation":[{"name":"Department of Anatomy Second Faculty of Medicine Charles University Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michal","family":"Polovin\u010d\u00e1k","sequence":"additional","affiliation":[{"name":"Department of Radiology Second Faculty of Medicine Charles University Motol University Hospital Prague Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Kachl\u00edk","sequence":"additional","affiliation":[{"name":"Department of Anatomy Second Faculty of Medicine Charles University Prague Czech Republic"},{"name":"Department of Health Care Studies College of Polytechnics Jihlava Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,8,24]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.1800621116"},{"key":"e_1_2_7_3_1","article-title":"Os supratrochleare dorsale del codo","author":"Canamero B.","year":"2014","journal-title":"Acta Rheuma"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.3109\/17453678709146457"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.25080\/Majora-92bf1922-00a"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-014-1926-7"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.141.1.123"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.25080\/Majora-92bf1922-011"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1148\/69.5.730"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1058-2746(09)80026-8"}],"container-title":["Journal of Anatomy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/joa.13233","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1111\/joa.13233","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/joa.13233","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,5]],"date-time":"2023-09-05T10:35:35Z","timestamp":1693910135000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/joa.13233"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8,24]]},"references-count":9,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2020,10]]}},"alternative-id":["10.1111\/joa.13233"],"URL":"https:\/\/doi.org\/10.1111\/joa.13233","archive":["Portico"],"relation":{},"ISSN":["0021-8782","1469-7580"],"issn-type":[{"value":"0021-8782","type":"print"},{"value":"1469-7580","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,8,24]]},"assertion":[{"value":"2019-07-20","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-05-13","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-08-24","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
