The International Society for the Advancement of Spine Surgery (ISASS) has published a new policy statement on bone grafting. An expert panel looked at alternatives to autologous bone grafting (ABG) and reviewed the available literature for five current strategies and techniques for bone grafting and compared them for safety and efficacy. They also compared the methods by regulatory approval pathway and quality of the clinical evidence supporting them. Their findings appear in the Feb. 2019 International Journal of Spine Surgery, the official ISASS journal.
