A retrospective study was conducted on eight patients who underwent AMPF for axis complex fractures at the General Hospital of Central Theater Command from February 2004 to October 2021. The types of axis injuries, reasons for injuries, surgery time, intraoperative blood loss, spinal cord injury classification (American Spinal Injury Association, ASIA), as well as complications and technical notes, were documented. This study included eight cases of type II Hangman\u2019s fracture, five cases of type II and three cases of type III odontoid process fracture. Five patients experienced traffic accidents, while three patients experienced falling injuries. All patients underwent AMPF surgery with an average intraoperative blood loss of 288.75\u00a0mL and a duration of 174.5\u00a0min. Two patients experienced dysphagia 1 month after surgery. The patients were followed up for an average of 15.63\u00a0months. One case improved from C to E in terms of neurological condition, three cases improved from D to E, and four cases remained at E. Bony fusion and Atlantoaxial Motion Preservation were successfully achieved for all eight patients. AMPF is a feasible and effective way for simultaneous odontoid process fracture and Hangman\u2019s fractures with C2\/3 instability, while preserving atlantoaxial movement.<\/jats:p>","DOI":"10.1038\/s41598-024-51367-2","type":"journal-article","created":{"date-parts":[[2024,1,6]],"date-time":"2024-01-06T04:22:11Z","timestamp":1704514931000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Anterior atlantoaxial motion preservation fixation technique for axis complex fractures (odontoid process with Hangman\u2019s fractures) and technique notes"],"prefix":"10.1038","volume":"14","author":[{"given":"Qilin","family":"Lu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin","family":"Tang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Xie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianzhong","family":"Mei","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hui","family":"Kang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ximing","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Xu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianhua","family":"Cai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,1,6]]},"reference":[{"issue":"4","key":"51367_CR1","doi-asserted-by":"publisher","first-page":"715","DOI":"10.1007\/s10140-022-02041-5","volume":"29","author":"Y Cai","year":"2022","unstructured":"Cai, Y. et al.
