Fast and reliable methods for predicting and monitoring in-vivo bone strength are of great importance for hip joint replacement. To avoid adaptive remodeling with cortical thinning and increased porosity of the bone due to stress shielding, in a preoperative planning process the optimal implant design, size, and position has to be determined. This process involves interactive implant positioning within the bone as well as simulation and visualization of the stress within bone and implant due to…

A set of novel algorithms and methods to improve an efficient simulation of breast deformation between the prone image and the supine surgery positioning are outlined, namely non-linear material properties, the sliding of the breast tissue on the chest wall, and a fine-tuning step to align the breast model to a measured surface.

This paper proposes a system that specifically includes the ability to handle multiple labels and their interfaces and implements a fast Integer Medial Axis algorithm, and suggests that using a local reconstruction scheme is a good approach to decouple the system from strict sampling limitations.

It is revealed that only at the proximal lateral and proximal medial aspects of the femur were some differences observed between the strain patterns of the prostheses studied, and the effect of stem stiffness on the strain deviation relatively to those obtained with the intact femur was assessed.

A massive decrease in stress in the region of the calcar femorale was found when the implants were in place, and it was concluded that this decrease could contribute substantially to the Calcar Femorale resorption sometimes observed in patients after total hip replacement.
