RT Journal Article SR Electronic T1 Synthetic Bone Graft Materials in Spine Fusion: Current Evidence and Future Trends JF International Journal of Spine Surgery JO Int J Spine Surg FD International Society for the Advancement of Spine Surgery SP 104 OP 112 DO 10.14444/8058 VO 15 IS s1 A1 Mark A. Plantz A1 Erik B. Gerlach A1 Wellington K. Hsu YR 2021 UL http://ijssurgery.com//content/15/s1/104.abstract AB Historically, iliac crest bone autograft has been considered the gold standard bone graft substitute for spinal fusion. However, the significant morbidity associated with harvesting procedures has influenced decision-making and practice patterns. To minimize these side effects, many clinicians have pursued the use of bone graft extenders to minimize the amount of autograft required for fusion in certain applications. Synthetic materials, including a variety of ceramic compounds, are a class that has been studied extensively as bone graft extenders. These have been used in combination with a wide array of other biomaterials and investigated in a variety of different spine fusion procedures. This review will summarize the current evidence of different synthetic materials in various spinal fusion procedures and discuss the future of novel synthetics.
