Abstract
The autolyzed antigen-extracted allogeneic (AAA) bone implant was placed into a 17-mm long diaphyseal periosteum-free defect in the radius in 27 rabbits. The animals were observed physically and roentgenologically every week. The continuity of the radius was evaluated macroscopically and histologically. Maximum length of the follow-up period was 114 days. The AAA implants were progressively resorbed and replaced by the recipient's bone growing from fragments of radius, restoring the continuity of diaphysis. Osteoinductive activity of the implant was transferred across a tube of a polyamide vascular prosthesis. There were no appreciable histologic signs or immune of foreign-body reaction.
