Head-neck CT images of 60 patients were included in this study. Maximum screw length, laminar thickness, the screw angle and the laminar height were measured. The feasibility of 3.5-mm diameter screw fixation and the potential risk of transverse foramen injury was analyzed. The TSF was safe at C3 and C4, but risky to the transverse foraman at a rate of 8.7% at C5 (0% on the left side and 20% on the right side), 33.3% at C6 (24.4% on the left side and 42.9% on the right side). C7 had the highest 77.8% rate (65.5% on the left side and 89.8% on the right side). The safe screw length was 27.7\u2009mm at C3, 27.4\u2009mm at C4, 28.0\u2009mm at C5, 25.6\u2009mm at C6 and 25.5\u2009mm at C7, respectively. The present study showed that translaminar screw could place the transverse foramen of C5\u2013C7 at risk. Preoperative CT scanning was necessary for safe screw placement.<\/jats:p>","DOI":"10.1038\/srep46611","type":"journal-article","created":{"date-parts":[[2017,4,21]],"date-time":"2017-04-21T05:58:59Z","timestamp":1492754339000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The risk of translaminar screw fixation to the transverse foramen of the lower cervical spine: a computed tomography study"],"prefix":"10.1038","volume":"7","author":[{"given":"Ganggang","family":"Kong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Ji","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zucheng","family":"Huang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junhao","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianting","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingan","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2017,4,21]]},"reference":[{"key":"BFsrep46611_CR1","doi-asserted-by":"publisher","first-page":"158","DOI":"10.1097\/00024720-200404000-00014","volume":"17","author":"NM Wright","year":"2004","unstructured":"Wright, N.
