The Initial Modelling of Hybrid Plating for Internal Fixation Construct by Using 3-D Bone Model

Abstract

The development of locking plate design provides benefits especially for more stable plate fixation in bone and allows better fracture joint development. Hybrid locking plate modelling as fixation on femur fracture by using a real bone model were investigated. Internal fixation modelling were successfully perfomed on ANSYS v.14.5 with the geometry of femur as a 3D bone model which was obtained from CT-scan process. The configuration of screw bone mounting with the N-L-N-L L-N-L-N pattern filled 8 holes in the locking plate. The mounting of bone screws in the fixation process induced the contact areas as the origin of stress development. It is worked as the support of the locking plate that has been locked with locking screw and it is expected to maintain a stable position of the femur bone on its position. The low stress on femur bone were obtained which means that the bone was not much sufferedd due to applied load and may also affect the bone healing process. The use of hybrid plating is expected to guarantee a fixed fixation condition so that the bone healing process by callus formation between broken bones can take place continuously.
