Human engineering on prosthesis

Cranioplasty prosthesis manufacturing based on reverse engineering technology

BACKGROUND Most patients with large focal skull bone loss after craniectomy are referred for cranioplasty. Reverse engineering is a technology which creates a computer-aided design (CAD) model of a real structure. Rapid prototyping is a technology which produces physical objects from virtual CAD models. The aim of this study was to assess the clinical usefulness of these technologies in craniop...

Human Knee Prosthesis Equipped with Force Sensors

In-vivo monitoring of human knee implants after total arthroplasty increases the knowledge about articular motion and loading conditions. The proposed knee prosthesis equipped with force sensors executes force measurements in polyethylene human knee prosthesis by two sensorized metal bars positioned under the femoral condyles and fully contained in the polyethylene insert. In this paper, a new ...

Actuating a Human Hand Prosthesis: Model Study

The researchers all over the world give a lot of attention to modeling the human hand in order to obtain good hand prosthesis. Despite many attempts, very few solutions are available on the market, and even those are far too expensive to reach for most of the patients. Knowing that it is very important to have a model as close as possible to the natural one, we determined the kinematical and dy...
