Traumatic spondylolisthesis of the axis, called hangman\u2019s fracture, frequently occurs as a high-energy trauma. However, nontraumatic spondylolisthesis of the axis is quite rare, and relevant literature on this condition is scarce. We reported a case of a 49-year-old man who had spondylolisthesis of the axis without experiencing a traumatic episode. Plain radiograph and CT image showed 7.0\u2009mm anterolisthesis of the axis. Both C2 and C3 facet joints positioned asymmetrically, and the unilateral side oriented coronally, which was less resistant to rotational motion. These facet joint abnormalities could cause segmental instability and spondylolisthesis of the axis. Due to the resultant myelopathy, the slip with cord compression was surgically corrected by posterior decompression with instrumented fusion.<\/jats:p>","DOI":"10.1155\/2020\/6859474","type":"journal-article","created":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T23:31:05Z","timestamp":1584660665000},"page":"1-3","source":"Crossref","is-referenced-by-count":1,"title":["Nontraumatic Spondylolisthesis of the Axis with Cervical Kyphosis"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9416-031X","authenticated-orcid":true,"given":"Shuhei","family":"Mizobuchi","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Kochi Medical School, Kochi University, Kohasu, Oko-cho, Nankoku 783-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuaki","family":"Tadokoro","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Kochi Medical School, Kochi University, Kohasu, Oko-cho, Nankoku 783-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shogo","family":"Takaya","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Kochi Medical School, Kochi University, Kohasu, Oko-cho, Nankoku 783-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsuhito","family":"Kiyasu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Kochi Medical School, Kochi University, Kohasu, Oko-cho, Nankoku 783-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryuichi","family":"Takemasa","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Kochi Medical School, Kochi University, Kohasu, Oko-cho, Nankoku 783-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4493-3657","authenticated-orcid":true,"given":"Masahiko","family":"Ikeuchi","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Kochi Medical School, Kochi University, Kohasu, Oko-cho, Nankoku 783-8505, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1097\/BOT.0000000000000952"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1148\/130.1.77"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1055\/s-0035-1563404"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1055\/s-0035-1550343"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0000000000000722"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/s00264-010-1203-5"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.4172\/2165-7939.1000308"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-7580.2001.19840431.x"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.22603\/ssrr.2017-0017"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0000000000001826"}],"container-title":["Case Reports in Orthopedics"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/crior\/2020\/6859474.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crior\/2020\/6859474.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/crior\/2020\/6859474.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T23:31:06Z","timestamp":1584660666000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/crior\/2020\/6859474\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,3,19]]},"references-count":10,"alternative-id":["6859474","6859474"],"URL":"https:\/\/doi.org\/10.1155\/2020\/6859474","relation":{},"ISSN":["2090-6749","2090-6757"],"issn-type":[{"type":"print","value":"2090-6749"},{"type":"electronic","value":"2090-6757"}],"subject":[],"published":{"date-parts":[[2020,3,19]]}}}
