However, the procedure is technically demanding and may result in complications such as hinge fracture, facet joint violation, and improper gutter placement. The authors present an operative video demonstrating O-arm\u2013based intraoperative navigation during open-door laminoplasty in a 75-year-old man with multilevel ossification of the posterior longitudinal ligament (OPLL) and severe cervical canal stenosis. Navigation allowed precise localization of the medial facet, controlled hinge preparation, and accurate screw placement. Postoperative CT confirmed adequate decompression without complications, suggesting that navigation may enhance the safety and precision of laminoplasty.<\/jats:p>\n \n The video can be found here:\n https:\/\/stream.cadmore.media\/r10.3171\/2026.4.FOCVID2630<\/jats:ext-link>\n <\/jats:p>","DOI":"10.3171\/2026.4.focvid2630","type":"journal-article","created":{"date-parts":[[2026,7,1]],"date-time":"2026-07-01T00:08:45Z","timestamp":1782864525000},"page":"V3","source":"Crossref","is-referenced-by-count":0,"title":["O-arm\u2013navigated open-door laminoplasty to reduce technical complications in multilevel cervical ossification of the posterior longitudinal ligament: operative video"],"prefix":"10.3171","volume":"15","author":[{"given":"Suchel","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryosuke","family":"Maruiwa","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Keio University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keung Nyun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seong","family":"Yi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dong-Ah","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chang-Kyu","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kota","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Keio University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoon","family":"Ha","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Severance Hospital, Yonsei University College of Medicine, Seoul, Republic of Korea; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"10","key":"b1","series-title":"Clin Spine Surg","first-page":"E553","article-title":"Accuracy of the gutter position in cervical double-door laminoplasty using intraoperative computed tomography navigation and the factors associated with C5 palsy","volume":"33","author":"Kudo H","year":"2020","unstructured":"Kudo H, Wada K, Kumagai G, Accuracy of the gutter position in cervical double-door laminoplasty using intraoperative computed tomography navigation and the factors associated with C5 palsy.
