  • Title: The osteoninductive property of decalcified bone matrix. An experimental study,
    Author: Tuli SM, Singh AD.
    Journal: J Bone Joint Surg Br; 1978 Feb; 60(1):116-23. PubMed ID: 342532.
    Abstract:
    Demineralised homologous bone-matrix implant was used to bridge a large circumferential osteoperiosteal gap in the diaphysis of the ulna of rabbits. Periodic observations of the graft were made clinically, radiologically, histologically and by tetracycline fluorescence up to forty-two weeks. By the twelfth week after operation 81 per cent of the animals revealed bone formation in the implant and complete bridging of the gap. The new bone was laid on the surface and in the substance of the matrix, suggesting that the inductive principle was acting locally. The bone, once formed, remodelled to the texture of a mature tubular bone and did not undergo absorption during a long follow-up period. Demineralise bone-matrix proved to be a highly osteoinductive and readily osteoconductive material. The graft did not evoke any appreciable local foreign-body or immunogenic reaction. The high degree of success in bridging massive bone defects justifies further serious studies and hopes for a useful substitute for massive autologous bone grafts.
