This monocentric study was conducted in the Spinal-Cord-Injury center of the Berufsgenossenschaftliches Klinikum Hamburg. Data sets of 199 patients from the Spinal-Cord-Injury center admitted between the beginning of 2003 and the end of 2018 were subjected to statistical analyses. The Spinal Cord Independence Measure II (SCIM II) difference between admission and discharge was chosen as the primary outcome variable of a multiple linear regression analysis, including several other variables. The length of fusion, SCIM at admission and the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) values at admission could be identified as significant predictors. The cervical fusion length could be identified as an independent predictor of the functional outcome within our model. This correlation most likely mediates for the range of motion as well as partly for injury severity. This is much harder to evaluate in a newly admitted rehabilitation patient than a single numerical value that represents its rehabilitative implications, such as fusion length. Together with an initial assessment of the SCIM and ISNCSCI, it provides a solid basis for outcome prediction.<\/jats:p>","DOI":"10.3390\/jcm11195867","type":"journal-article","created":{"date-parts":[[2022,10,8]],"date-time":"2022-10-08T23:39:31Z","timestamp":1665272371000},"page":"5867","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The Correlation between Cervical Fusion Length and Functional Outcomes in Patients with Traumatic Spinal Cord Damage\u2014A Registry-Based Cohort Study"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8845-276X","authenticated-orcid":false,"given":"Yannick","family":"Rau","sequence":"first","affiliation":[{"name":"Faculty of Medicine, Universit\u00e4t zu L\u00fcbeck, 23562 L\u00fcbeck, Germany"},{"name":"Spinal-Cord-Injury Center, BG Klinikum Hamburg, 21033 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roland","family":"Thietje","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Universit\u00e4t zu L\u00fcbeck, 23562 L\u00fcbeck, Germany"},{"name":"Spinal-Cord-Injury Center, BG Klinikum Hamburg, 21033 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4927-549X","authenticated-orcid":false,"given":"Arndt-Peter","family":"Schulz","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Universit\u00e4t zu L\u00fcbeck, 23562 L\u00fcbeck, Germany"},{"name":"Zentrum Klinische Forschung, BG Klinikum Hamburg, 21033 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc","family":"Auerswald","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, BG Klinikum Hamburg, 21033 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3037-8066","authenticated-orcid":false,"given":"Ralf","family":"B\u00f6thig","sequence":"additional","affiliation":[{"name":"Spinal-Cord-Injury Center, BG Klinikum Hamburg, 21033 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Hirschfeld","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Universit\u00e4t zu L\u00fcbeck, 23562 L\u00fcbeck, Germany"},{"name":"Spinal-Cord-Injury Center, BG Klinikum Hamburg, 21033 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"E10","DOI":"10.3171\/FOC.2008.25.11.E10","article-title":"Prevalence of cervical spinal injury in trauma","volume":"25","author":"Milby","year":"2008","journal-title":"Neurosurg.
