The paper deals with the clinical experience in the use of a biological adhesive system in conjunction with bone transplants to close large bone defects. The gluing technique has been exactly described, 11 patients with a follow-up between 9 and 21 months are being presented. The application of this system which consists of highly concentrated native fibronogen, thrombin, and clotting factor XIII results in an acceleration of homogenous incorporation of the implants. No deterioration of wound healing occurred. The advantages of this method are: exact local hemostasis, adhesive strength, and plasticity.

The influence of a biological tissue glue--based on fibrinogen clotting--on bone healing has been investigated in animal experiments. Standardized cortical defects in the tibiae of rabbits were closed with a plug of homologous or heterologous fibrin. The course of restoration has been studied using histological techniques, x-ray examinations and isotopes (Ci 99 TC). Heterologous fibrin delays bone formation, due to a local immune response. Homologous fibrin on the other hand cubances and accelerates sprouting of capillary vessels and connective tissue cells which results in rapid new formation of bone.

At 89 Patients with painfull wrist and clinical symptoms like a lesion of the triangular disc, arthrography of the radiocarpal joint was performed. In 18 cases with corresponding arthrographical findings removal of the disc results in clear recovery respectively painlessness. That simple operation seems to be an alternative to the resection of the ulna and a replaceable method if symptomatology and arthrography are accordingly. The described proceeding becomes important because no recovery was seen by conservative treatment.
