Design Optimization of Hip Resurfacing Prosthesis Using Finite Element Analysis
Hip resurfacing is an alternative to total hip arthroplasty for the young and active patient likely to outlive traditional means of hip joint replacement. To optimize design on the hip resurfacing prosthetic stress profile in the proximal femur after hip resurfacing. The acetabular cup is implanted in much the same fashion as an uncemented total hip arthroplasty, however, implantation of the fe...
متن کاملShape Design Optimization of Unimorph Piezoelectric Cantilever Energy Harvester
The most promising method for micro scale energy scavenging is via vibration energy harvesting which converts mechanical energy to electrical energy. Using piezoelectric cantilevers is the most common method for vibration energy harvesting. Changing the shape of the cantilevers can lead to changing the generated output voltage and power. In this work vibration energy harvesting via piezoelectri...
متن کاملActive Shape Models for Customised Prosthesis Design
Images and computer graphics play an increasingly important role in the design and manufacture of medical prostheses and implants. Images provide guidance on optimal design in terms of location, preparation and the overall shape and configuration of subcomponents. Direct manipulation of a graphical representation provides a natural design environment. RaPiD is a CAD-like knowledge-based assista...
متن کاملDesign and Fabrication of Polymer-ceramic Composite Hip Prosthesis
A composite hip prosthesis (CHP) made from alumina reinforced ultra high molecular weight polyethylene (UHMWPE) was designed and manufactured. The main objective of the study was to fabricate the composite hip prosthesis which would be an ideal replacement of metallic one as bone is a composite material consisting of collagen fibre matrix and embedded hydroxyapatite mineral. With this idea we d...
متن کاملStress-based Design of a Femoral Hip Prosthesis
INTRODUCTION In the normal hip, stress is distributed over the entire crossection of the femur. Bending and axial compression are the major modes of loading. Following THA, the stress in the bone is significantly different mainly due to the manner in which the load is transferred to the femur (Huiskes, 1990, Huiskes, 1995). In this case, the load is primarily transferred through shear across th...
