China. Email: huangcy0595@sina.com Purpose: This study biomechanically compared a novel semi-cannulated lateral mass screw with cement augmentation against conventional solid screws for stabilizing loosened cervical lateral masses under cyclic loading.\nMethods: Eight fresh human cervical specimens underwent \u03bcCT scanning for BMD assessment. Each specimen received both screw types: on the augmentation side, semi-cannulated screws were initially loosened via pull-out testing then reinserted with cement; on the (contralateral) primary side, conventional solid screws were placed Awithout augmentation. After cyclic loading, vertical displacement, toggling angle, and rotation center distance (ORC) at the screw-bone interface were measured, followed by final pull-out force tests.\nResults: The mean BMD of the lateral masses was 305.05 \u00b1 48.33 mg\/cm\u00b3. Following cyclic loading, the augmentation side exhibited a significantly higher pull-out force than its initial state (P &lt; 0.01), though not statistically greater than the primary side. Under cyclic loading, the augmentation side demonstrated significantly superior stability: vertical displacement increased by only 6.25%, compared to a 70.69% increase on the primary side (P &lt; 0.05). The toggling angle decreased by 2.36% on the augmentation side, versus a significant 79.92% increase on the primary side (P &lt; 0.05). The ORC increased by 2.13% on the augmentation side, markedly lower than the 38.03% increase on the primary side.\nConclusion: The novel semi-cannulated lateral mass screw with cement augmentation demonstrated superior dynamic stability and significantly improved fixation strength after cyclic loading compared to conventional solid screws, offering a promising revision strategy for cervical spines with screw loosening or osteoporosis.<\/jats:p>","DOI":"10.52628\/92.3.15488","type":"journal-article","created":{"date-parts":[[2026,10,15]],"date-time":"2026-10-15T22:37:13Z","timestamp":1792103833000},"source":"Crossref","is-referenced-by-count":0,"title":["A Novel Semi-Cannulated Screw with Cement Augmentation for Revision Lateral Mass Fixation: A Cyclic Loading Biomechanical Study"],"prefix":"10.52628","volume":"92","author":[{"given":"CANYANG","family":"HUANG","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ZHIPING","family":"HUANG","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"ZHENQIANG","family":"WANG","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XIUHUA","family":"WU","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"QINGAN","family":"ZHU","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"DONGBIN","family":"QU","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"27062","published-online":{"date-parts":[[2026,10]]},"container-title":["Acta Orthopaedica Belgica"],"original-title":[],"deposited":{"date-parts":[[2026,10,15]],"date-time":"2026-10-15T22:37:14Z","timestamp":1792103834000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.actaorthopaedica.be\/archive\/volume-92\/autumn\/experimental-basic-science-research\/a-novel-semi-cannulated-screw-with-cement-augmentation-for-revision-lateral-mass-fixation-\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,10]]}},"URL":"https:\/\/doi.org\/10.52628\/92.3.15488","relation":{},"ISSN":["0001-6462"],"issn-type":[{"value":"0001-6462","type":"print"}],"subject":[],"published":{"date-parts":[[2026,10]]}}}
