However, accurate placement is challenging due to the inherent risk of neurovascular complications. Navigation technology based on intraoperative 3D imaging allows highly accurate screw placement, yet studies specifically investigating screw placement in patients with traumatic atlantoaxial injuries are scarce. The aim of this study was to compare atlantoaxial screw placement as treatment of traumatic instabilities using iCT-based navigation or fluoroscopic-guidance with intraoperative 3D control scans.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>This was a retrospective review of patients with traumatic atlantoaxial injuries treated operatively with dorsal stabilization of C1 and C2. Patients were either assigned to the intraoperative navigation or fluoroscopic-guidance group. Screw accuracy, procedure time, and revisions were compared.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Seventy-eight\u00a0patients were included in this study with 51\u00a0patients in the navigation group and 27\u00a0patients in the fluoroscopic-guidance group. In total, 312 screws were placed in C1 and C2. Screw accuracy was high in both groups; however, pedicle perforations\u2009&gt;\u20091\u00a0mm occurred significantly more often in the fluoroscopic-guidance group (<jats:italic>P<\/jats:italic> =\u20090.02).

When comparing these data with other studies, the application of different classification systems for assessment of screw accuracy should be considered.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00586-024-08232-7","type":"journal-article","created":{"date-parts":[[2024,4,18]],"date-time":"2024-04-18T14:01:48Z","timestamp":1713448908000},"page":"2304-2313","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Comparison of iCT-based navigation and fluoroscopic-guidance for atlantoaxial screw placement in 78 patients with traumatic cervical spine injuries"],"prefix":"10.1007","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3955-0339","authenticated-orcid":false,"given":"Jula","family":"Gierse","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Mandelka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonia","family":"Medrow","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benno","family":"Bullert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul A.","family":"Gruetzner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jochen","family":"Franke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8024-9276","authenticated-orcid":false,"given":"Sven Y.","family":"Vetter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,4,18]]},"reference":[{"issue":"5","key":"8232_CR1","doi-asserted-by":"publisher","first-page":"905","DOI":"10.1007\/s00586-014-3424-6","volume":"24","author":"SB Jazayeri","year":"2015","unstructured":"Jazayeri SB, Beygi S, Shokraneh F, Hagen EM, Rahimi-Movaghar V (2015) Incidence of traumatic spinal cord injury worldwide: a systematic review.
