Abstract
Introduction: Osseointegration are a particular kind of prosthesis that is inserted a short titanium rod or screw into the bone surgically and joined to the prosthetic limb.Experimental part: This study looked at a patient's gait analysis with above-knee amputation wearing osseointegration prosthesis implant when walking above force plate. Evaluated the mechanical and fatigue properties of a Ti13Nb13Zr alloy implant.Theoretical part: Drawing and analysis a femoral bone model with an osseointegration implant using Ansys Workbench 17.2.Results and discussion: The results of the tensile testing showed an ultimate tensile strength of 553 MPa, average yield strength of 480 MPa, an elongation of 19.66%, and a Young's modulus of 2.73 GPa. Furthermore, a compressive strength of 1010 MPa and compression yield strength of 700 MPa were found by compression testing. The results of fatigue testing, which were displayed as S-N curves, highlighted the alloy's time-dependent fatigue behavior by showing decreasing fatigue strength with an increase in cycles. Force plate showed amaximum force of 600 N was reported. A strong safety margin was shown by Finite Element Analysis in the bone containing the implant, with safety factors often more than 5 and low deformation (2.4 mm) appropriate for prosthetic uses. A good static design was confirmed by the Von-Mises stress distribution, which was primarily below 46 MPa.Conclusion: Comprehensive results confirm the mechanical feasibility of the Ti13Nb13Zr alloy for prosthetic applications and offer important new information for improving prosthetic design, guaranteeing durability, and improving safety in practical applications.
