To the best of our knowledge, a patient presenting with a traumatic occipital condyle fracture and pre-existing occipitalisation of the atlas has not been previously reported. We report the case of a 79-year-old man presenting with an Anderson and Montesano type III fracture through a fused occipital condyle and lateral mass. This fracture was noted to extend into the transverse foramen and the C1\u2013C2 joint space. The transverse ligament and ligamentum flavum were calcified but not disrupted and the atlantodental interval was within normal limits. The neurological examination was unremarkable with the exception of neck pain. The patient was treated conservatively and placed in a rigid cervical collar for 10\u2005weeks with serial CT studies to monitor healing of the fracture. At 4\u2005months of follow-up, the patient was pain free with nearly complete resolution of his occipital condyle fracture.<\/jats:p>","DOI":"10.1136\/bcr-2015-209623","type":"journal-article","created":{"date-parts":[[2015,5,14]],"date-time":"2015-05-14T14:54:52Z","timestamp":1431615292000},"page":"bcr2015209623","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Occipital condyle fracture in a patient with occipitalisation of the atlas"],"prefix":"10.1136","volume":"2015","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9522-8734","authenticated-orcid":false,"given":"Shane M","family":"Burke","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taylor A","family":"Huhta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles E","family":"Mackel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ron I","family":"Riesenburger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2015,5,14]]},"reference":[{"key":"2025042706200850000_2015.may14_1.bcr2015209623.1","doi-asserted-by":"publisher","DOI":"10.3171\/2009.5.SPINE08866"},{"key":"2025042706200850000_2015.may14_1.bcr2015209623.2","doi-asserted-by":"publisher","DOI":"10.1227\/NEU.0b013e3182775527"},{"key":"2025042706200850000_2015.may14_1.bcr2015209623.3","first-page":"294","article-title":"Occipitalization of the atlas","volume":"24","author":"Srisopark","year":"1974","journal-title":"J Dent Assoc Thai"},{"key":"2025042706200850000_2015.may14_1.bcr2015209623.4","unstructured":"Wackenhein A .
