The entry point of the C1ZAS was defined as the projection point of the inner of the recess to the posterior arch and the trajectory should be angled cephalad by 8.7° and medially by 0°. The 61 patients (122 sides) with AAD or AAI were classified into three groups: the low-risk (76 sides, 62%), the intermedial-risk (18 sides, 15%), and the high-risk (28 sides, 23%) groups. Satisfactory C1ZAS placement and atlantoaxial reduction were achieved in all eight patients with AAD and unilateral/bilateral narrow C1 pedicles. No instance of C1ZAS placement-related VA injury or dural laceration was observed.</p><p><strong>Conclusions: </strong>When the placement of C1 PS is not feasible in patients with AAD and unilateral/bilateral narrow C1 pedicles, C1ZAS placement with \"in-out-in\" technique can be considered an effective alternative option, providing tricortical or quadricortical purchase for rigid fixation of the atlas.</p>","PeriodicalId":19566,"journal":{"name":"Orthopaedic Surgery","volume":" ","pages":"437-445"},"PeriodicalIF":1.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11787991/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142770951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
