An Investigation of Using RCS-processed Intramedullary Stainless Steel 316L Nail in the Treatment of Diaphyseal Bone Fractures

The method of intramedullary nailing, which leads to the alignment of the diaphyseal broken bone, is one of the diaphyseal fractured bone healing novelties. The rods utilized must be strong enough to withstand the forces exerted by the transplanted bone. Today, various researchers are interested in using severe plastic deformation (SPD) methods to improve the mechanical characteristics of metals. One of the SPD procedures used in this study was repetitive corrugation and straightening (RCS) on a 316L stainless steel rod. After conducting mechanical characteristics tests on the rods produced using this approach, ABAQUS software was utilized to simulate the intramedullary nailing finite element method (FEM). The results of the experiments revealed that raising the number of pressing stages to eight significantly increases the hardness of the samples. The simulation findings revealed that the bone sample implanted by the rod manufactured by the aforementioned procedure has a higher structural hardness than the bone implanted by a basic 316L stainless steel rod under various stress conditions.
