Included studies were those that reported results of 1\u20134 levels ACDF using pure structural allograft compared with a mechanical interbody device augmented with an osteobiologic. Excluded studies were those that reported on ACDF with cervical corpectomy; anterior and posterior cervical fusions; circumferential (360\u00b0 or 540\u00b0) fusion or revision ACDF for nonunion or other conditions.

All included studies compared fusion rates following ACDF among structural allograft vs non-allograft interbody device\/osteobiologic pairs. Fusion rates were reported between 84% and 100% for structural allograft, while fusion rates for various interbody device\/osteobiologic combinations ranged from 26% to 100%. Among non-allograft cage groups fusion rates varied from 73-100%. One study found PEEK cages filled with combinations of autograft, allograft, and demineralized bone matrix (DBM) to have an overall fusion rate of 26%. In one study comparing plate and zero-profile constructs, there was no difference in fusion rates for two-level fusions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>There was limited data comparing fusion outcomes of patients undergoing ACDF using structural allograft vs interbody devices augmented with osteobiologic materials to support superiority of one method.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/21925682231171857","type":"journal-article","created":{"date-parts":[[2024,2,29]],"date-time":"2024-02-29T09:53:21Z","timestamp":1709200401000},"page":"34-42","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Structural Allograft Versus Mechanical Interbody Devices Augmented With Osteobiologics in Anterior Cervical Discectomy and Fusion: A Systematic Review"],"prefix":"10.1177","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9983-3365","authenticated-orcid":false,"given":"Amit","family":"Jain","sequence":"first","affiliation":[{"name":"Orthopaedic Surgery, Johns Hopkins Medicine, Baltimore, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suraj","family":"Dhanjani","sequence":"additional","affiliation":[{"name":"Johns Hopkins University, Baltimore, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Harris","sequence":"additional","affiliation":[{"name":"Orthopaedic Surgery, Johns Hopkins Medicine, Baltimore, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"Cartagena","sequence":"additional","affiliation":[{"name":"Johns Hopkins University, Baltimore, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob","family":"Babu","sequence":"additional","affiliation":[{"name":"Orthopaedic Surgery, Johns Hopkins Medicine, Baltimore, MD, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Riew","sequence":"additional","affiliation":[{"name":"Weill Cornell Brain and Spine Center, New York, NY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Shin","sequence":"additional","affiliation":[{"name":"Mass General Brigham Inc, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeffrey C.","family":"Wang","sequence":"additional","affiliation":[{"name":"USC Spine Center, Los Angeles, CA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0497-1130","authenticated-orcid":false,"given":"S.
