Given the high rate of pseudarthrosis in multilevel stand-alone ACDF, there is a need to explore the utility of novel grafting materials. In this study, the authors present a single-institution retrospective study of patients with multilevel degenerative spine disease who underwent multilevel stand-alone ACDF surgery with or without cellular allograft supplementation.<\/jats:p>\n <\/jats:sec>\n \n METHODS<\/jats:title>\n In a prospectively collected database, 28 patients who underwent multilevel ACDF supplemented with cellular allograft (ViviGen) and 25 patients who underwent multilevel ACDF with decellularized allograft between 2014 and 2020 were identified. The primary outcome was radiographic fusion determined by a 1-year follow-up CT scan. Secondary outcomes included change in Neck Disability Index (NDI) scores and change in visual analog scale scores for neck and arm pain.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n The study included 53 patients with a mean age of 53 \u00b1 0.7 years who underwent multilevel stand-alone ACDF encompassing 2.6 \u00b1 0.7 levels on average. Patient demographics were similar between the two cohorts. In the cellular allograft cohort, 2 patients experienced postoperative dysphagia that resolved by the 3-month follow-up. One patient developed cervical radiculopathy due to graft subsidence and required a posterior foraminotomy. At the 1-year CT, successful fusion was achieved in 92.9% (26\/28) of patients who underwent ACDF supplemented with cellular allograft, compared with 84.0% (21\/25) of patients who underwent ACDF without cellular allograft. The cellular allograft cohort experienced a significantly greater improvement in the mean postoperative NDI score (p < 0.05) compared with the other cohort.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n Cellular allograft is a low-morbidity bone allograft option for ACDF. In this study, the authors determined favorable arthrodesis rates and functional outcomes in a complex patient cohort following multilevel stand-alone ACDF supplemented with cellular allograft.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2021.3.focus2150","type":"journal-article","created":{"date-parts":[[2021,7,1]],"date-time":"2021-07-01T02:31:04Z","timestamp":1625106664000},"page":"E7","source":"Crossref","is-referenced-by-count":10,"title":["Cellular allograft for multilevel stand-alone anterior cervical discectomy and fusion"],"prefix":"10.3171","volume":"50","author":[{"given":"Alec W.","family":"Gibson","sequence":"first","affiliation":[{"name":"School of Medicine and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdullah H.","family":"Feroze","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Washington, Seattle, Washington; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Madeline E.","family":"Greil","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Washington, Seattle, Washington; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret E.","family":"McGrath","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Washington, Seattle, Washington; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sananthan","family":"Sivakanthan","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Washington, Seattle, Washington; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabrielle A.","family":"White-Dzuro","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Brigham and Women\u2019s Hospital, Boston, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John R.","family":"Williams","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Washington, Seattle, Washington; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher C.","family":"Young","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Washington, Seattle, Washington; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph P.","family":"Hofstetter","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Washington, Seattle, Washington; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"207","key":"r1","series-title":"Paraplegia","first-page":"213","article-title":"The pathology of vascular disorders of the spinal cord","volume":"2","author":"Hughes JT","year":"1965","unstructured":"Hughes JT.
