For the 10 BMP studies, doses varied from 0.26 to 2.1\u00a0mg in 649 patients with fusion rates of 95.3 to 100% at 12\u00a0months. For other osteobiologics, each of six studies reported one type of osteobiologic in certain dose\/concentration\/volume in a total of 580 patients with fusion rates of 6.8 to 96.9% at 12\u00a0months. Risk of bias was low in three of the 13 non-randomized (18.75%) and in all the three randomized studies (100%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Taking into account the inconsistent reporting within available literature, for BMP usage in ACDF, doses lower than 0.7\u00a0mg per level can achieve equal successful fusion rates as higher doses, and there is no complication-free dose proved yet. It seems that the lower the dose the lower the incidence of serious complications. As for non-BMP osteobiologics the studies are very limited for each osteobiologic and thus conclusions must be drawn individually and with caution.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/21925682231195766","type":"journal-article","created":{"date-parts":[[2024,2,29]],"date-time":"2024-02-29T09:53:21Z","timestamp":1709200401000},"page":"129-140","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Dosing Strategy for Osteobiologics Used in ACDF Surgery: Influence on Fusion Rates and Associated Complications.
