In this case, we describe a patient with a combination of AAD, an anterior arch fracture of the atlas, and a rare congenital anomaly known as atlanto-occipital assimilation (AOA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation:<\/jats:title>\n                    <jats:p>A 70-year-old man presented with posterior neck pain and right-sided torticollis following an accident that collision with a car while riding an electric scooter. Radiographic findings confirmed posterior AAD with anterior arch fracture of C1 in the inherent setting of AOA. The patient showed no neurologic deficit, so a closed reduction technique using Gardner-Wells tongs was attempted in an awakened state, and successful reduction could achieve without a neurologic deficit. After about three months of rigid brace application, head and neck motion was allowed, and no recurrence of dislocation or cervical pain occurred during the follow-up period of about one year.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>Because the posterior AAD is usually accompanied by anterior arch fracture of atlas, the transverse atlantal ligament remained intact. So nonoperative management after manual reduction was possible. The presence of a C1 anterior arch fracture observed in our case can be regarded as an indicator predicting the success of closed reduction of AAD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Our case highlighted the successful nonoperative management of traumatic posterior AAD with an accompanying anterior arch fracture of the atlas in a peculiar inherent combination of AOA through the closed reduction technique and rigid cervical brace application.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2023.109133","type":"journal-article","created":{"date-parts":[[2023,12,12]],"date-time":"2023-12-12T21:43:44Z","timestamp":1702417424000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Traumatic posterior dislocation of atlanto-axial joint with anterior arch fracture in the patient of atlanto-occipital assimilation: A case report"],"prefix":"10.1097","volume":"114","author":[{"given":"Sungan","family":"Hong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gang-Un","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"issue":"6","key":"R1-47-20260325","article-title":"Complete atlantooccipital assimilation with basilar invagination and atlantoaxial subluxation treated non-surgically: a case report","volume":"9","author":"Electricwala,","year":"2017","journal-title":"Cureus"},{"issue":"3","key":"R2-47-20260325","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1055\/s-0034-1376371","article-title":"A review of the diagnosis and treatment of atlantoaxial dislocations","volume":"4","author":"Yang,","year":"2014","journal-title":"Global Spine J."},{"issue":"7","key":"R3-47-20260325","doi-asserted-by":"crossref","first-page":"1212","DOI":"10.1016\/j.injury.2012.01.013","article-title":"Traumatic atlantoaxial rotatory subluxation (TAARS) in adults: a report of two cases and literature review","volume":"43","author":"Venkatesan,","year":"2012","journal-title":"Injury"},{"issue":"4","key":"R4-47-20260325","doi-asserted-by":"crossref","first-page":"E128","DOI":"10.1097\/BRS.0b013e3181bad0c2","article-title":"Single stage reduction and stabilization of basilar invagination after failed prior fusion surgery in children with Down's syndrome","volume":"35","author":"Hedequist,","year":"2010","journal-title":"Spine (Phila Pa 1976)"},{"issue":"5","key":"R5-47-20260325","doi-asserted-by":"crossref","first-page":"975","DOI":"10.31616\/asj.2023.0030","article-title":"Radiological study of atlas arch defects with meta-analysis and a proposed new classification","volume":"17","author":"Suphamungmee,","year":"2023","journal-title":"Asian Spine J."},{"issue":"1","key":"R6-47-20260325","doi-asserted-by":"crossref","first-page":"612","DOI":"10.1186\/s12891-019-3005-2","article-title":"Traumatic posterior Atlanto-axial dislocation: case report of an atypical C1-C2 dislocation with an anterior arch fracture of C1","volume":"20","author":"Ghailane,","year":"2019","journal-title":"BMC Musculoskelet.
