[Testing of an intramedullary reinforcement in osteosynthesis bridging of bone defects using methylmethacrylate]

The purpose of this testing was to determine whether the routinely used intramedullary metallic plate can be replaced by our newly constructed metallic reinforcement ladder without interfering with the static properties of the bone alignment. Our results showed that the alignment obtained by the application of the new metallic reinforcement had the same static value as the formerly used technique. The new technique is superior to the former one as concerns the bending loads due to the greater distance between the external osteosynthesis plate and the reinforcement, and because of the greater friction between the reinforcement and methyl-methacrylate than between the metallic plate and methyl-methacrylate.
