the function of our tissues and organs. Among the biomedical materials, titanium alloys have received attractions for dental and orthopedic implants due to their high strength, great corrosion resistance and biocompatibility, and low density [1,2]. Recently, a series of new β titanium alloys have been developed with low elastic modulus, containing non-toxic alloying elements such as Nb, Ta, Zr ...

This study evaluated the feasibility of using three-dimensional printing (3DP) to fabricate porous titanium implants. Titanium powder was blended with a water-soluble binder material. Green, porous, titanium implants fabricated by 3DP were sintered under protective argon atmosphere at 1,200, 1,300, or 1,400°C. Sintered implant prototypes had uniform shrinkage and no obvious shape distortion aft...

Introduction: Recently, intramedullary nailing for displaced middle third fractures of clavicle has received wide attention. Though open nailing has been widely described, closed nailing finds less mention. This paper therefore aims to study the outcome of closed titanium elastic nailing for displaced mid-clavicular fractures. Material and Methods: This was a prospective study of 34 patients wi...

Femur fractures are common long bone injuries in children which account for less than 2% of all paediatric fractures. Although these fractures are dramatic and disabling injuries for the child and parent, the good part is that they unite rapidly with minimal complications if aligned well. Various methods have been used successfully to treat these fractures, but they differ in their stability an...

Radiation therapy, in conjunction with surgical implant fixation, is a common combined treatment in cases of bone metastases. However, metal implants generally used in orthopedic implants perturb radiation dose distributions. Carbon-Fiber Reinforced Polyetheretherketone (CFR-PEEK) material has been recently introduced for production of intramedullary nails and plates. The purpose of this work w...

This work presents a numerical approach in order to predict the influence of implant material stiffness in a femoral component design when submitted in compression. The implant success depends on the transferred load to the neighboring bone. The finite element method can be used to analysis the stress and strain distribution in the femoral component allowing to improve the implant selection. Fo...
