Thus, a file review was performed and patients with complete documentation of neurological status at preoperative, postoperative, 12\u00a0month, 3\u20134\u00a0years follow-up including surgical reports for reoperation with a minimum follow-up of 9\u00a0years were included. Final follow-up assessment included a physical examination, assessment of pain levels, Odoms criteria, Neck disability index. The degeneration of each cervical segment at preoperative and at final follow-up was assessed using an MRI. Forty-six out of 68 included patients participated, the mean follow-up was 11 (range 9\u201315) years, at which 71.7% of patients were free of arm pain, 52.2% of patients were free of neck pain, 63% of patients had no sensory dysfunction, and full motor strength was noted in 95.6% of patients. The clinical success rate was 76.1%, the mean NDI was 12%. Overall repeated procedure rate was 17%, the reoperation rate for sASD was 9%, and removal of CDA was performed in 4%. MRI showed progressive degeneration but no significant changes of SDI from preoperative to final follow-up.<\/jats:p>","DOI":"10.1038\/s41598-022-17652-8","type":"journal-article","created":{"date-parts":[[2022,8,3]],"date-time":"2022-08-03T12:03:37Z","timestamp":1659528217000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Long-term follow-up MRI shows no hastening of adjacent segment degeneration following cervical disc arthroplasty"],"prefix":"10.1038","volume":"12","author":[{"given":"Benedikt W.","family":"Burkhardt","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lukas","family":"Baumann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreas","family":"Simgen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gudrun","family":"Wagenpfeil","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philipp","family":"Hendrix","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wolfgang","family":"Reith","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joachim M.","family":"Oertel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2022,8,3]]},"reference":[{"key":"17652_CR1","doi-asserted-by":"publisher","first-page":"S52","DOI":"10.1097\/BRS.0b013e31826d60fb","volume":"37","author":"BD Lawrence","year":"2012","unstructured":"Lawrence, B.
