[A new way of producing autogenous cancellous bone graft (author's transl)].

Transplantation of autogenous cancellous bone graft is used with an increasing frequency in the operative treatment of fractures or in reconstructive procedures for stimulating bone healing, replacing traumatic or other defects, treating non-unions, especially in septic conditions. The amount of autogenous cancellous bone available for transplantation often is below the requirements in certain cases, e.g. in large bone defects or when repeated transplantations have to be done. To cover these needs, the author filled the donor site in the iliac crest with large amount of "specially treated" (disantigenized) calf cancellous bone. 10 weeks later a known quantity of fibrous reticular tissue with osteo-inductive capacity filled the framework of the implanted graft, which could be transplanted as autogenous cancellous bone. The procedure can be repeated according to further requirements.
