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…

Computational Steering for Implant Planning in Orthopedics
TLDR
This work presents the first planning system that allows for an implant selection based on the patient-specific prediction of the stress distribution, and provides a virtual 3D planning environment, where the physician can interactively insert implants into the bone.
A 3D Simulation System for Hip Joint Replacement Planning
TLDR
A tool for hip joint replacement planning is presented that allows the surgeon to rank the long-term stability of an implant, and the application of this tool is shown in a clinical routine setting.
Stress Tensor Field Visualization for Implant Planning in Orthopedics
TLDR
The application of advanced 3D visualization techniques to determine the optimal implant design and position in hip joint replacement planning can immediately react to changes in the simulated stress tensor field and provide an effective means for optimal implant selection and positioning in a computational steering environment.
Interactive Computing in Pre-operative Planning of Joint Replacement
TLDR
An integration framework applicable to different engineering applications which supports distributed simulations as well as visualisation on-the-fly and enables real time interactive computational steering is introduced and its integration into a previously existing pre-operative planning environment for joint replacement surgery is presented.
Non-standard bone simulation: interactive numerical analysis by computational steering
TLDR
This article investigates an application to pre-surgical planning of a total hip replacement where it is desirable to select an optimal implant for a specific patient, and proposes methods on how the FCM can be made computationally efficient to the extent that it can be used for patient specific, interactive bone simulations.
Towards Navigated Breast Surgery Using Efficient Breast Deformation Simulation
TLDR
Specific extensions of a highly efficient dynamic corotated finite element method (FEM) are proposed to incorporate non-linear material properties while maintaining stability and speed of the original simulation.
Efficient Breast Deformation Simulation
TLDR
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.
Conformal multi-material mesh generation from labelled medical volumes
TLDR
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.
The Finite Cell Method for Geometry-Based Structural Simulation
TLDR
A CT-derived data specific integration scheme for the FCM which accelerates the stiffness matrices computation by precomputation with respect to material constants and voxel dimensions is presented.
Physically-based Simulation of Cuts in Deformable Bodies: A Survey
TLDR
This report presents a coherent summary of the state-of-the-art in virtual cutting of deformable bodies, focusing on the distinct geometrical and topological representations of the deformable body, as well as the specific numerical discretizations of the governing equations of motion.

TLDR
The system enables the simulation of the operation and the construction of a custom-made implant depending on the chosen resection planes and the patient's anatomy and the combination of multi-modal image information (CT and MR) enables an accurate 3D visualization of the bone tumor within the bone.

TLDR
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.

TLDR
Although immediate full-weight bearing was strongly recommended to the patients, no implant subsidence was seen in the treatment follow-up X ray studies and any fractures or fissures could be avoided through the use of Robodoc.

TLDR
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.
