The positions of each VBT screw were analyzed using intraoperative computed tomography (CT) scans performed for image guidance during VBT. Differences for screws placed using an open versus thoracoscopic approach were noted for the screw position in each vertebra, distance from the spinal canal, unicortical versus bicortical placement, the distance of screw tips from the thoracic aorta, and impingement of screws on adjacent rib heads.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Seventy three (73)\u00a0screws in ten (10)\u00a0patients were available for analysis. Only 21% of screws were placed traversing the middle one-third of the vertebral body, without spinal canal penetration, with the distal tip placed unicortically or bicortically as planned, and without touching the thoracic aorta. The rates of non-ideal screw placement were not significantly different for screws placed via thoracoscopic versus open approaches. Five (5)\u00a0screws (6.8%) penetrated the spinal canal 1\u20132\u00a0mm, but without known clinical sequelae.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion<\/jats:title>\n            <jats:p>The majority of VBT screws available for analysis were placed in non-ideal positions, suggesting that accurate screw placement using intraoperative fluoroscopy and anatomic landmarks can be challenging, but without adverse clinical consequences.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1007\/s43390-024-00970-4","type":"journal-article","created":{"date-parts":[[2024,9,19]],"date-time":"2024-09-19T16:08:19Z","timestamp":1726762099000},"page":"153-158","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Accuracy of screw placement during vertebral body tethering using fluoroscopic guidance and anatomic landmarks"],"prefix":"10.1007","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8870-8286","authenticated-orcid":false,"given":"Kevin M.","family":"Neal","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-0304-1791","authenticated-orcid":false,"given":"Kylie","family":"Krombholz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4553-2054","authenticated-orcid":false,"given":"Mona","family":"Doshi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,9,18]]},"reference":[{"issue":"13","key":"970_CR1","doi-asserted-by":"publisher","first-page":"1169","DOI":"10.2106\/JBJS.19.00980","volume":"102","author":"DG Hoernschemeyer","year":"2020","unstructured":"Hoernschemeyer DG et al (2020) Anterior vertebral body tethering for adolescent scoliosis with growth remaining: a retrospective review of 2 to 5-year postoperative results.
