The primary outcome was the C2-7 Cobb angle and secondary outcomes were Neck Disability Index (NDI), modified Japanese Orthopaedic Association (mJOA) scale, revision rates, T1 slope and C2-7 sagittal vertical axis (C2-7 SVA) at final follow-up. Logistic regression analysis adjusted for potential confounders (i.e. age, operated levels, and follow-up). Results: Preoperative C2-7 Cobb angle and T1 slope were higher in the laminectomy group, while the C2-7 SVA was similar. The decrease in C2-7 Cobb angle from pre- to postoperatively was more pronounced in the laminectomy group (\u2212\u20096\u00b0 (IQR 20) versus \u22121\u00b0 (IQR 7), <jats:italic>p<\/jats:italic>\u2009=\u20090.002). When adjusting for confounders, the decrease in C2-7 Cobb angle remained higher in the laminectomy group (coefficient\u2009\u2212\u200912 (95% confidence interval (CI) \u221218 to \u22125), <jats:italic>p<\/jats:italic>\u2009=\u20090.001). However, there were no adjusted differences for postoperative NDI (\u2212\u200911 (\u2212\u200923 to 2), <jats:italic>p<\/jats:italic>\u2009=\u20090.10), mJOA, revision rates, T1 slope and C2-7 SVA. Conclusion: Posterior cervical laminectomy without fusion is associated with mild loss of cervical lordosis of around 6\u00b0 in the mid-term after approximately five years, however without any clinical relevance regarding NDI or mJOA in well-selected patients (particularly in shorter segment laminectomies of\u2009&lt;\u20093 levels).<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00586-024-08260-3","type":"journal-article","created":{"date-parts":[[2024,6,2]],"date-time":"2024-06-02T19:01:23Z","timestamp":1717354883000},"page":"3109-3116","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Cervical kyphosis after posterior cervical laminectomy with and without fusion"],"prefix":"10.1007","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6133-3314","authenticated-orcid":false,"given":"Thorsten","family":"Jentzsch","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oliver T.","family":"Wetzel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Armaan K.","family":"Malhotra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher S.","family":"Lozano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric M.","family":"Massicotte","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jos\u00e9 M.","family":"Spirig","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael G.","family":"Fehlings","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mazda","family":"Farshad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,6,2]]},"reference":[{"issue":"3S","key":"8260_CR1","doi-asserted-by":"publisher","first-page":"S33","DOI":"10.1093\/neuros\/nyw083","volume":"80","author":"JR Wilson","year":"2017","unstructured":"Wilson JR et al (2017) State of the art in degenerative cervical myelopathy: an update on current clinical evidence.
