The Prestige I Cervical Disc System has been used clinically since June 1998, and long-term results can now begin to be assessed. The authors conducted clinical and radiographic examinations at 3 and 4 years postoperatively to evaluate the long-term performance of the Prestige I device.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A pilot trial was initiated in which the Prestige I disc was implanted in a cohort of patients with end-stage disease, who often had a history of multiple previous fusion procedures. All patients were followed according to a standardized clinical and radiographic protocol until 2 years postoperatively. Outcome measures included the Short Form\u201336 (SF-36) and Neck Disability Index (NDI) questionnaires, neurological status, and radiographic status. To evaluate the long-term function of the device, Ethics Committee approval was obtained to assess the patients at 3 and 4 years postoperatively. All patients were contacted, and after signing an additional informed consent document, were reevaluated according to the standardized protocol.<\/jats:p>\n                    <jats:p>Of the 17 patients in the original cohort, 13 were evaluated at 3 years and 14 were evaluated at 4 years postoperatively. Clinical outcome measures including the NDI and SF-36 showed good improvement, especially when the end-stage nature of the disease is considered. Radiographic analysis showed that the Prestige I disc maintained motion at the treated segment at 3 and 4 years postoperatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In this report the authors demonstrate the clinical viability of the Prestige I cervical disc system at long-term postoperative intervals, even in the more severe biomechanical environment of end-stage disease.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/foc.2004.17.3.10","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T07:03:01Z","timestamp":1201158181000},"page":"69-71","source":"Crossref","is-referenced-by-count":58,"title":["Long-term outcome after implantation of the Prestige I disc in an end-stage indication: 4-year results from a pilot study"],"prefix":"10.3171","volume":"17","author":[{"given":"James T.","family":"Robertson","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Newton H.","family":"Metcalf","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"p_1","first-page":"533","volume":"16","author":"Cherubino P","year":"1990","journal-title":"Ital J Orthop Traumatol"},{"key":"p_2","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1958.15.6.0602"},{"key":"p_3","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1998.88.6.0943"},{"key":"p_4","doi-asserted-by":"publisher","DOI":"10.1097\/00024720-200308000-00002"},{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-199904000-00009"},{"key":"p_6","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199707150-00009"},{"key":"p_7","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199904010-00011"},{"key":"p_8","doi-asserted-by":"publisher","DOI":"10.1097\/00006123-199902000-00078"},{"key":"p_10","first-page":"223","volume":"96","author":"Robinson RA","year":"1955","journal-title":"Bull Johns Hopkins Hosp"},{"key":"p_11","doi-asserted-by":"publisher","DOI":"10.1001\/jama.196.6.479"},{"key":"p_12","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199503010-00004"},{"key":"p_14","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-200211150-00006"},{"key":"p_15","doi-asserted-by":"publisher","DOI":"10.1097\/00024720-200310000-00002"}],"container-title":["Neurosurgical Focus"],"original-title":[],"link":[{"URL":"https:\/\/thejns.org\/view\/journals\/neurosurg-focus\/17\/3\/foc.2004.17.3.10.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/thejns.org\/downloadpdf\/journals\/neurosurg-focus\/17\/3\/foc.2004.17.3.10.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/thejns.org\/downloadpdf\/journals\/neurosurg-focus\/17\/3\/foc.2004.17.3.10.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,30]],"date-time":"2026-05-30T08:31:37Z","timestamp":1780129897000},"score":1,"resource":{"primary":{"URL":"https:\/\/thejns.org\/view\/journals\/neurosurg-focus\/17\/3\/foc.2004.17.3.10.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,9]]},"references-count":13,"journal-issue":{"issue":"3"},"URL":"https:\/\/doi.org\/10.3171\/foc.2004.17.3.10","relation":{},"ISSN":["1092-0684"],"issn-type":[{"value":"1092-0684","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,9]]}}}
