Modular adaptive bone plate for humerus bone osteosynthesis.
The present paper describes a bionics application of shape memory alloy in construction of orthopedic implant. The main idea of this paper is related to design modular adaptive implants for fractured bones. In order to target the efficiency of medical treatment, the implant has to protect the fractured bone, for the healing period, undertaking much as is possible from the daily usual load of the healthy bones. The adaptability of this design is related to medical possibility of the doctor to made the implant to correspond to patient specifically anatomy. Using a CT-realistic numerical humerus bone model, the mechanical simulation of the osteosyntesis process for humerus bone using staples made out of Nitinol. The stress and displacements diagrams for bone, for plate modules and for staples, are presented.
