Our technique aims to achieve stability of the atlanto-occipital and atlantoaxial joints while preserving mobility of the upper cervical spine.<\/jats:p><jats:p>\n            Patients and Methods\u2003Two male patients, 43 years and 29 years of age, respectively, were admitted to our hospital due to a fracture of the ventral arch of the atlas with no damage of the transverse atlantal ligament. Both men also presented a congenital cleft of the posterior arch. Initial conservative management with a halo-thoracic vest was performed in one case and failed. As a result, surgical treatment was performed in both cases using bilateral C1 mass screws and a transverse connector.<\/jats:p><jats:p>\n            Results\u2003The patients showed no neurologic deficits on follow-up examination 4 weeks after surgery with a full range of head and neck motion. Computed tomography (CT) showed no dislocation of the implanted material with good dorsal alignment and a stable ventral fracture distance. Follow-up CT showed osseous stability in both cases with the beginning of bony ossification of the bone graft.<\/jats:p><jats:p>\n            Conclusion\u2003Isolated instable fractures of the ventral arch of the atlas with a congenital cleft of the posterior arch with no damage of the transverse atlantal ligament can be stabilized using bilateral C1 mass screws and a transverse connector preserving upper cervical spine mobility.<\/jats:p>","DOI":"10.1055\/s-0037-1603636","type":"journal-article","created":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T18:45:39Z","timestamp":1498157139000},"page":"066-072","source":"Crossref","is-referenced-by-count":0,"title":["Ventral C1 Fracture Combined with Congenital Posterior Cleft: What to Do?"],"prefix":"10.1055","volume":"79","author":[{"given":"Philipp","family":"Dammann","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital Essen, University of Duisburg-Essen, Germany"},{"name":"Department of Neurosurgery, University Hospital Geneva, University of Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tobias","family":"Schoemberg","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital Essen, University of Duisburg-Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yahya","family":"Ahmadipour","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital Essen, University of Duisburg-Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Payer","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital Geneva, University of Geneva, Switzerland"},{"name":"Department of Neurosurgery, Hirslanden Klinik, Z\u00fcrich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ulrich","family":"Sure","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital Essen, University of Duisburg-Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enrico","family":"Tessitore","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital Geneva, University of Geneva, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neriman","family":"\u00d6zkan","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital Essen, University of Duisburg-Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oliver","family":"Gembruch","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital Essen, University of Duisburg-Essen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2017,6,22]]},"container-title":["Journal of Neurological Surgery Part A: Central European Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0037-1603636.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,1,18]],"date-time":"2019-01-18T02:21:55Z","timestamp":1547778115000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0037-1603636"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,6,22]]},"references-count":0,"journal-issue":{"issue":"01","published-online":{"date-parts":[[2018,1,2]]},"published-print":{"date-parts":[[2018,1]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0037-1603636","relation":{},"ISSN":["2193-6315","2193-6323"],"issn-type":[{"value":"2193-6315","type":"print"},{"value":"2193-6323","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,6,22]]}}}
