The reported patient has a congenital malformation of the cervical spine, which is frequently observed in patients with Klippel\u2013Feil syndrome. Her posterior arch of the atlas (C1) is hypoplastic and a chronic subluxation of the atlanto-axial joint would be possible. Although most common fusions in Klippel\u2013Feil syndrome patients exist at C2\/3, the majority of studies about Klippel\u2013Feil syndrome deal with pediatric or adolescent individuals. Through extreme flexion of her neck, there was a compression of the spinal cord by the odontoid process. This led to a quadriplegia lasting about 10\u2009min. Over the following weeks, all of her symptoms started to diminish. This situation turned out to be the third episode involving temporary neurological disorders in this 60-year-old female\u2019s life.<\/jats:p>","DOI":"10.1177\/2050313x18823387","type":"journal-article","created":{"date-parts":[[2019,1,12]],"date-time":"2019-01-12T00:17:25Z","timestamp":1547252245000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Congenital deformation of the posterior arch of the atlas: Subluxation of the atlanto-axial joint with temporary quadriplegia"],"prefix":"10.1177","volume":"7","author":[{"given":"Tobias M","family":"Ballhause","sequence":"first","affiliation":[{"name":"Department of Trauma, Hand and Reconstructive Surgery, University Hospital Hamburg-Eppendorf, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirko","family":"Velickovic","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Sports Traumatology and Trauma Surgery, Wolfenb\u00fcttel Municipal Hospital, Wolfenb\u00fcttel, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darius M","family":"Thiesen","sequence":"additional","affiliation":[{"name":"Department of Trauma, Hand and Reconstructive Surgery, University Hospital Hamburg-Eppendorf, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Dreimann","sequence":"additional","affiliation":[{"name":"Department of Trauma, Hand and Reconstructive Surgery, University Hospital Hamburg-Eppendorf, Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2019,1,11]]},"reference":[{"key":"bibr1-2050313X18823387","doi-asserted-by":"publisher","DOI":"10.1155\/2017\/6131703"},{"key":"bibr2-2050313X18823387","doi-asserted-by":"publisher","DOI":"10.1016\/j.jspd.2017.12.002"},{"key":"bibr3-2050313X18823387","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-018-3876-9"},{"key":"bibr4-2050313X18823387","unstructured":"Menger RP, Notarianni C.
