New Developments of Ti-Based Alloys for Biomedical Applications
TL;DR: Efforts have been made to reveal the latest scenario of bulk and porous Ti-based materials for biomedical applications, emphasizing their current status, future opportunities and obstacles for expanded applications.
Journal ArticleDOI
Direct metal fabrication of titanium implants with tailored materials and mechanical properties using electron beam melting technology
TL;DR: In this paper, the design and fabrication of tailored titanium implant components having tailored mechanical properties that mimic the stiffness of bone to reduce stress shielding and bone remodeling is discussed, and results are verified using mechanical testing.
Journal ArticleDOI
Review: titanium and titanium alloy applications in medicine
TL;DR: The use of titanium and titanium alloys for use in biomedical applications is reviewed, finding titanium exhibits superior corrosion resistance and tissue acceptance when compared with stainless steels and Cr-Co-based alloys.

Titanium as a Biomaterial for Implants
TL;DR: The first metal alloy developed specifically for human use was the "vanadium steel" but it was no longer used in implants because its corrosion resistance is inadequate in vivo as mentioned in this paper, and the wrought CoNiCrMo alloy is relatively new, now used for making the stems of prostheses for heavily loaded joints such as the knee and hip.

Hip Implant Design With Three-Dimensional Porous Architecture of Optimized Graded Density
TL;DR: The architected hip implant presented in this work shows clinical promise in reducing bone loss while preventing implant micromotion, thereby contributing to reduce the risk of periprosthetic fracture and the probability of revision surgery.

Journal ArticleDOI
The effect of stem stiffness on femoral bone resorption after canine porous-coated total hip arthroplasty.
TL;DR: Femora with the flexible stems consistently showed much less bone resorption than those with the stiff stems, and gross differences in femoral bone remodeling were observed both roentgenographically and histologically.
Journal ArticleDOI
The influence of prosthetic stem stiffness and of a calcar collar on stresses in the proximal end of the femur with a cemented femoral component.
TL;DR: Three-dimensional finite-element models of the proximal end of the femur were used to examine the influence of stem material, stem geometry, and the use of a calcar collar on the stresses in and around implanted total hip-replacement femoral components.
