Abstract
For the first time all relevant adhesive groups were analyzed for their adhesive strength in bone-surgery. After having glued bone pieces in a special designed system, the tensil- and shearing-strength was determined. All adhesives showed a loss of adhesive strength under in vivo-conditions. Moderate moisture increased the tensile strength in some adhesives. While the fibrin adhesive had only a low adhesive strength under simulated in vivo-conditions, the adhesives containing gelatine, epoxy resin or acrylates reached reasonable results. The relationship between chemical structure and adhesive strength will be further used for the development of a special bone adhesive as a new surgeon's tool.
