Methods: this was a retrospective observational study of OCF identified from trauma cases admitted between December 2011 and December 2019 by the neurosurgery team at a Type 3 trauma center. Results: a total of twenty-eight occipital condyle fractures were identified in twenty-six patients. The incidence was less than 0.2% per year and more common in male patients (4:1 ratio) involved in traffic accidents. The mean age was 42.08 years. Anderson and Montesano type II and Tuli type 1 were the most frequent (67.9% and 89.3%, respectively) and no case presented C0-C1-C2 instability. All patients were treated with a cervical collar for 3 to 6 months. About 65% of the patients exhibited good progression (Glasgow Outcome Scale equal to 4), and the severity of traumatic brain injury was the main determinant for negative outcomes. Conclusion: the findings of this study are in accordance with available literature data. The use of external stabilization with a cervical collar is reinforced for the treatment of stable lesions, even when these are bilateral. Assessment of the patients\u2019 follow-up results in the studied sample may contribute with useful information for the treatment of occipital condyle fractures.<\/jats:p>","DOI":"10.1590\/0100-6991e-20213024","type":"journal-article","created":{"date-parts":[[2021,11,29]],"date-time":"2021-11-29T07:29:52Z","timestamp":1638170992000},"source":"Crossref","is-referenced-by-count":2,"title":["Observational study of patients with occipital condyle fracture at a brazilian referral trauma center"],"prefix":"10.1590","volume":"48","author":[{"given":"ANDREW VIN\u00cdCIUS DE SOUZA","family":"BATISTA","sequence":"first","affiliation":[{"name":"Santa Casa de S\u00e3o Paulo School of Medical Science, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3206-2081","authenticated-orcid":false,"given":"GUILHERME BRASILEIRO","family":"AGUIAR","sequence":"additional","affiliation":[{"name":"Santa Casa de S\u00e3o Paulo School of Medical Science, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"PRISCILLA","family":"BENNETT","sequence":"additional","affiliation":[{"name":"Santa Casa de S\u00e3o Paulo School of Medical Science, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M\u00c1RCIA RAMOS","family":"UMIGI","sequence":"additional","affiliation":[{"name":"Santa Casa de S\u00e3o Paulo School of Medical Science, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"JOS\u00c9 CARLOS ESTEVES","family":"VEIGA","sequence":"additional","affiliation":[{"name":"Santa Casa de S\u00e3o Paulo School of Medical Science, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2021]]},"reference":[{"key":"ref1","first-page":"469","article-title":"Surgical observations","volume":"4","author":"Bell C","year":"1817","journal-title":"Middlesex Hospital Journal"},{"issue":"7","key":"ref2","doi-asserted-by":"crossref","first-page":"731","DOI":"10.1097\/00007632-198807000-00004","article-title":"Morphology and treatment of occipital condyle fractures","volume":"13","author":"Anderson PA","year":"1988","journal-title":"Spine (Phila Pa 1976)"},{"key":"ref3","doi-asserted-by":"crossref","first-page":"106","DOI":"10.1227\/NEU.0b013e3182775527","article-title":"Occipital condyle fractures","volume":"72","author":"Theodore N","year":"2013","journal-title":"Neurosurgery"},{"issue":"5","key":"ref4","doi-asserted-by":"crossref","first-page":"1261","DOI":"10.2214\/ajr.178.5.1781261","article-title":"Radiologic and clinical spectrum of occipital condyle fractures retrospective review of 107 consecutive fractures in 95 patients","volume":"178","author":"Hanson JA","year":"2002","journal-title":"AJR Am J Roentgenol"},{"issue":"2","key":"ref5","doi-asserted-by":"crossref","first-page":"289","DOI":"10.1007\/s00586-011-1963-7","article-title":"Occipital condyle fractures Prospective follow-up of 31 cases within 5 years at a level 1 trauma centre","volume":"21","author":"Mueller FJ","year":"2012","journal-title":"Eur Spine J"},{"key":"ref6","series-title":"Occipital Condyle Fractures","first-page":"S114","volume":"50","year":"2002"},{"issue":"2","key":"ref7","doi-asserted-by":"crossref","first-page":"368","DOI":"10.1097\/00006123-199708000-00006","article-title":"Occipital condyle fractures","volume":"41","author":"Tuli S","year":"1997","journal-title":"Neurosurgery"},{"issue":"4","key":"ref8","first-page":"265","article-title":"Implanta\u00e7\u00e3o de registro de trauma como ferramenta para melhorar a qualidade do atendimento a traumatizados os primeiros 12 meses","volume":"42","author":"Parreira JG","year":"2015","journal-title":"Rev Col Bras Cir"},{"key":"ref9","doi-asserted-by":"crossref","first-page":"309","DOI":"10.1007\/978-3-319-62515-7_44","article-title":"The Decision-Making Process in Traumatic Lesions of the Craniovertebral Junction An Evidence-Based Approach?
