When a bone is fractured, bone-plate is inserted into the human body to fix the bone. Usually the plate is made of metallic materials proved biocompatible safety. In the environment where bone begins to be recovered just, it is disadvantageous to act for the simple high strength plate. The reason is that this sites do not provide the best environment where according to the study of Perren, the initial resilience is the best when inter-fragmentary strain of the bone is 2~10%. In this study, Compliant Mechanism was applied to the Locking Compression Plate in order to design a plate with improved the drawback. Then, it was analyzed using a finite element analysis program ABAQUS and compared to the conventional bone-plate.

Bone-plate inserted into the human body fixes the bone fractured. The plate is usually made of metallic materials. In the environment where bone is recovered, it is detrimental to act for the plate. The reason is that if the strength of the bone-plate is too high relative than that of bone, the plate bears most of the load receiving while the fracture is recovering, whereby the stress shielding phenomenon is caused in the bone. As a result, the bone due to the reduced stimulation causing low bone density has a greater risk of re-fracture. The purpose of this study is to design a Locking Compression Plate applied with Compliant Mechanism in order to improve the drawback and to analyze with a finite element analysis program ABAQUS and to compared to the conventional plate.
