Because the points of insertion are under the end of the inferior articular process, and because the screws are inserted toward the lateral side, there is less soft tissue development than with the conventional technique; the <jats:styled-content style=\"fixed-case\">CBT<\/jats:styled-content> technique therefore enables less invasive surgery than the conventional technique. However, it has some drawbacks. For example, in the original <jats:styled-content style=\"fixed-case\">CBT<\/jats:styled-content> approach, the points of insertion are in the vicinity of the end of the inferior articular process. Because this joint has been destroyed in many patients who have indications for intervertebral fusion surgery, it is sometimes difficult to use it as a reference point for screw insertion location. With severe lateral slippage, the screw insertion site can become significantly dislocated sideways, with possible resultant damaging to the spinal canal and\/or nerve root. The <jats:styled-content style=\"fixed-case\">CBT<\/jats:styled-content> technique here involved inserting the screws while keeping clear of the intervertebral foramen with the assistance of side view <jats:styled-content style=\"fixed-case\">X<\/jats:styled-content>\u2010ray fluoroscopy and using the end of the inferior articular process and the isthmus as points of reference for screw location.<\/jats:p>","DOI":"10.1111\/os.12122","type":"journal-article","created":{"date-parts":[[2014,9,1]],"date-time":"2014-09-01T12:26:12Z","timestamp":1409574372000},"page":"244-248","source":"Crossref","is-referenced-by-count":42,"title":["Isthmus\u2010guided Cortical Bone Trajectory for Pedicle Screw Insertion"],"prefix":"10.1111","volume":"6","author":[{"given":"Koichi","family":"Iwatsuki","sequence":"first","affiliation":[{"name":"Department of Neurosurgery Osaka University Medical School  Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiki","family":"Yoshimine","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Osaka University Medical School  Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu\u2010ichiro","family":"Ohnishi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Osaka University Medical School  Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kosi","family":"Ninomiya","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Osaka University Medical School  Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshika","family":"Ohkawa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Osaka University Medical School  Osaka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2014,9]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199106000-00009"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199311000-00016"},{"key":"e_1_2_4_4_1","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.92B8.24237"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinbiomech.2006.11.007"},{"key":"e_1_2_4_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2008.07.008"},{"key":"e_1_2_4_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0000000000000116"},{"key":"e_1_2_4_8_1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1979.51.2.0172"}],"container-title":["Orthopaedic Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fos.12122","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/os.12122","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,2]],"date-time":"2023-10-02T11:12:25Z","timestamp":1696245145000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/os.12122"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,8]]},"references-count":7,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2014,8]]}},"alternative-id":["10.1111\/os.12122"],"URL":"https:\/\/doi.org\/10.1111\/os.12122","archive":["Portico"],"relation":{},"ISSN":["1757-7853","1757-7861"],"issn-type":[{"value":"1757-7853","type":"print"},{"value":"1757-7861","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,8]]}}}
