Materials and Methods: Prospectively collected data of 56 patients with CSM have been analyzed. The mean age at surgery was 35.6 years (range: 25\u201343 years). The mean follow-up was 28.2 months (range: 13\u201342 months). The range of motion (ROM) of the index segments, as well as upper and lower adjacent segments, was measured before surgery and at final follow-up. The C2-C7 sagittal vertical axis (SVA), C2-C7 cervical lordosis (CL), and T1 slope minus cervical lordosis (T1s-CL) were analyzed as well. Pain intensity was measured preoperatively and during follow-up using an 11-point numeric rating scale (NRS). Modified Japanese Orthopaedic Association (mJOA) score was assessed preoperatively and during follow-up for the clinical assessment of myelopathy. Surgical and implant-associated complications were analyzed as well. Results: The NRS pain score improved from a mean of 7.4 (\u00b11.1) preoperatively to a mean of 1.5 (\u00b10.7) at last follow-up (p &lt; 0.001). The mJOA score improved from a mean of 13.1 (\u00b12.8) preoperatively to a mean of 14.8 (\u00b12.3) at last follow-up (p &lt; 0.001). The mean ROM of the index levels increased from 5.2\u00b0 (\u00b13.0) preoperatively to 7.3\u00b0 (\u00b13.2) at last follow-up (p &lt; 0.05). Four patients developed heterotopic ossifications during follow-up. One patient developed permanent dysphonia. Conclusions: CDA showed good clinical and radiological outcome in this cohort of young patients. The motion of index segments could be preserved. CDA may be a viable treatment option in selected patients with CSM.<\/jats:p>","DOI":"10.3390\/jpm13040592","type":"journal-article","created":{"date-parts":[[2023,3,29]],"date-time":"2023-03-29T02:03:53Z","timestamp":1680055433000},"page":"592","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Clinical and Radiological Outcome of Disc Arthroplasty for the Treatment of Cervical Spondylotic Myelopathy"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4923-1064","authenticated-orcid":false,"given":"Peter","family":"Obid","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Freiburg University Hospital, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6171-8292","authenticated-orcid":false,"given":"Anastasia","family":"Rakow","sequence":"additional","affiliation":[{"name":"Center for Orthopaedics, Trauma Surgery and Rehabilitation Medicine, Greifswald University Hospital, 17475 Greifswald, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0685-1909","authenticated-orcid":false,"given":"Gernot Michael","family":"Lang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Freiburg University Hospital, 79106 Freiburg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolfgang","family":"Marx","sequence":"additional","affiliation":[{"name":"Spine and Scoliosis Center, Asklepios Klinik Wiesbaden, 65197 Wiesbaden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Niemeyer","sequence":"additional","affiliation":[{"name":"Spine and Scoliosis Center, Asklepios Klinik Wiesbaden, 65197 Wiesbaden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamim","family":"Rahim","sequence":"additional","affiliation":[{"name":"Spine and Scoliosis Center, Asklepios Klinik Wiesbaden, 65197 Wiesbaden, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"193","DOI":"10.1016\/j.ocl.2009.12.010","article-title":"Cervical Spondylotic Myelopathy: A Review of the Evidence","volume":"41","author":"Klineberg","year":"2010","journal-title":"Orthop.
