We demonstrate the application of advanced 3D visualization techniques to determine the optimal implant design and position in hip joint replacement planning. Our methods take as input the physiological stress distribution inside a patient's bone under load and the stress distribution inside this bone under the same load after a simulated replacement surgery. The visualization aims at showing principal stress directions and magnitudes, as well as differences in both distributions. By…

Interactive Residual Stress Modeling for Soft Tissue Simulation
An interactive method to compute a physically meaningful patient-specific residual stress distribution by using doctors' experience to sketch directional stress strokes and specify stress magnitudes at a few control points on the body surface is presented.
Biomechanical Analysis of Femur with THA and RHA implants using CT-Image Based Finite Element Method
A novel three-dimensional finite element analysis to analyze biomechanical changes in a femur with two different type of hip prosthesis provides an effective method for planning implants that are ideal for patients and for designing future implants that preserves the biomechanics of the femur to maintain its physiology.
Visualization of Human Spine Biomechanics for Spinal Surgery
A visualization application that facilitates methods such as multiple coordinated views, abstraction and focus and context to display simulation outcomes in a dedicated tool, and introduces new concepts to show the directions of impact force vectors, which were not accessible before.
Distance Visualization for Interactive 3D Implant Planning
The major findings of the performed user study indicate that a visualization that can facilitate an instant and quantitative analysis of distances between two objects in interactive 3D scenarios is demanding, yet can be achieved by including additional monocular cues into the visualization.
Non-standard bone simulation: interactive numerical analysis by computational steering
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.
Feel the inside: A haptic interface for navigating stress distribution inside objects
This paper presents a virtual perception system, which leverages a multi-finger haptic interface to help users intuitively perceive 3D stress fields and provides user a natural and straightforward understanding of the stress distribution without interacting with the parameters in the mapped visual representations.
Medical Visualization and Simulation for Customizable Surgical Guides
An extensive computerassisted surgery (CAS) literature study is performed, a novel optimization technique for customizable surgical guides (CSG) is developed, and three visualization techniques are introduced to make the planning more realistic and allow for remote visualization.
A Globally Conforming Lattice Structure for 2D Stress Tensor Visualization
The capability of the proposed visualization technique to show the global and local structure of a given stress field, based on the construction of a globally conforming lattice, is demonstrated.
The 3D Trajectory-based Stress Visualizer
3D-TSV provides a modular and generic implementation of key algorithms required for a trajectory-based visual analysis of principal stress directions, including the automatic seeding of space-filling stress lines, their extraction using numerical schemes, their mapping to an effective renderable representation, and rendering options to convey structures with special mechanical properties.


Computational Steering for Patient-Specific Implant Planning in Orthopedics
A prototype of a visual analysis tool that considers patient-specific biomechanical properties of the bone to select the optimal implant design, size, and position according to the prediction of individual load transfer from the implant to the bone is presented.
Numerical investigations of stress shielding in total hip prostheses
Stress shielding was demonstrated in both periprosthetic femora and diaphyseally, the femoral neck prosthesis SPIRON, in contrast to the conventional uncemented long-stem prosthesis BICONTACT, causes no decrease in the strain distribution and thus no stress shielding.
New aspects and approaches in pre-operative planning of hip reconstruction: a computer simulation
BackgroundAll computer-aided surgery technologies assume that the surgeon knows the best position for the implant components. However, there is indirect evidence that simple anatomical information
A CT-based high-order finite element analysis of the human proximal femur compared to in-vitro experiments.
A novel, empirically validated high-order finite element method (FEM) for simulating the bone response to loads of human femurs based on QCT data for clinical computer aided decision making is presented.

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.
Simulation of hip operations and design of custom-made endoprostheses using virtual reality techniques.
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.

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 thecalcar femurale resorption sometimes observed in patients after total hip replacement.

Computer-assisted hip navigation offers the potential for more accurate placement of hip components and control of leg length and offset and results of computer-assisted navigation in the future may be improved by incorporation of measurements of each patient's pelvic tilt, femoral stem position, and hip kinematics.
Computed Tomography-Based Navigation for Hip, Knee, and Spine Surgery
Computed tomography-based navigation for orthopaedic surgery provides greater accuracy and reproducibility than conventional surgery, but software improvements are needed to bring it into daily clinical routine.
