There is still much controversy over the ideal candidate for anterior odontoid screw fixation (AOSF), with outcomes affected by characteristics such as fracture morphology, nonideal body habitus, and osteoporosis. Therefore, this systematic review seeks to discuss the optimal criteria, indications, and adverse postoperative considerations when deciding to pursue AOSF.<\/jats:p>\n<\/jats:sec>\n\nMethods: <\/jats:title>\nThis investigation was conducted from experiential recall and article selection performed using the PubMed electronic bibliographic databases. The search yielded 124 articles that were assessed and filtered for relevance. Following the screening of titles and abstracts, 48 articles were deemed significant for final selection.<\/jats:p>\n<\/jats:sec>\n\nResults: <\/jats:title>\nAOSF is often utilized to treat Type IIB odontoid fractures, which has been shown to preserve atlantoaxial motion, limit soft-tissue injuries\/blood loss\/vertebral artery injury\/reduce operative time, provide adequate osteosynthesis, incur immediate spinal stabilization, and allow motion preservation of C1 and C2. However, this technique is limited by patient characteristics such as fracture morphology, transverse ligament rupture, remote injuries, short neck or inability to extend neck, barrel chested, and severe spinal kyphosis, in addition to adverse postoperative outcomes such as dysphagia and vocal cord paralysis.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nDue to the fact that odontoid fractures have a significant morbidity in elderly population, treatment with AOSF is generally recommended for this population with higher risk for nonoperative fusion. Considerations should be made to achieve fracture stability and fusion, while lowering the risk for operative and postoperative complications.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_165_2021","type":"journal-article","created":{"date-parts":[[2021,4,19]],"date-time":"2021-04-19T13:14:23Z","timestamp":1618838063000},"page":"170","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Determination and optimization of ideal patient candidacy for anterior odontoid screw fixation"],"prefix":"10.25259","volume":"12","author":[{"given":"Brian","family":"Fiani","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Desert Regional Medical Center, Palm Springs, California, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thao","family":"Doan","sequence":"additional","affiliation":[{"name":"University of Texas Medical Branch at Galveston, Galveston, Texas, United States,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudia","family":"Covarrubias","sequence":"additional","affiliation":[{"name":"School of Medicine, Anahuac Quer\u00e9taro University, Santiago de Quer\u00e9taro, M\u00e9xico,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Shields","sequence":"additional","affiliation":[{"name":"College of Human Medicine, Michigan State University, East Lansing, Michigan, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manraj","family":"Sekhon","sequence":"additional","affiliation":[{"name":"William Beaumont School of Medicine, Oakland University, Rochester, Michigan, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Rose","sequence":"additional","affiliation":[{"name":"School of Medicine, University of New Mexico, Albuquerque, New Mexico, United States."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2021,4,19]]},"reference":[{"key":"10.25259\/SNI_165_2021\/ref-1","doi-asserted-by":"crossref","first-page":"1065","DOI":"10.1097\/00007632-198910000-00007","article-title":"Fractures of the odontoid process.
