Ligament-Bone Interaction in a Three-Dimensional Model of the Knee
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In mathematical knee-joint models, the ligaments are usually represented by straightline elements, connecting the insertions of the femur and tibia. Such a model may not be valid if a ligament ...
Microdamage and Osteocyte-Lacuna Strain in Bone: A Microstructural Finite Element Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Damage accumulation in living tissues occurs when the rate of damage formation is greater than the rate of damage repair. For very large increases in the loading rate of bones, this can ...
The Predictive Value of Stress Shielding for Quantification of Adaptive Bone Resorption Around Hip Replacements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The presence of a femoral hip stem changes local mechanical signals inside the surrounding bone. In this study we examined the hypothesis that the eventual loss of bone can be estimated from ...
Mathematical Optimization of Elastic Properties: Application to Cementless Hip Stem Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The designer of a cementless hip stem in total hip replacement must find a balance between two conflicting demands. On the one hand, a stiff stem shields the surrounding bone from mechanical ...
Recruitment of Knee Joint Ligaments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: On the basis of earlier reported data on the in vitro kinematics of passive knee-joint motions of four knee specimens, the length changes of ligament fiber bundles were determined by using ...
Effects of Fit and Bonding Characteristics of Femoral Stems on Adaptive Bone Remodeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bone atrophy caused by stress-shielding may cause serious complications for the long-term fixation of hip stems. In particular, uncemented total hip arthroplasty is threatened by this problem, ...
Development and Validation of a Three-Dimensional Finite Element Model of the Pelvic Bone
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to both its shape and its structural architecture, the mechanics of the pelvic bone are complex. In Finite Element (FE) models, these aspects have often been (over) simplified, sometimes ...
Effects of Data Smoothing on the Reconstruction of Helical Axis Parameters in Human Joint Kinematics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In biomechanical joint-motion analyses, the continuous motion to be studied is often approximated by a sequence of finite displacements, and the Finite Helical Axis (FHA) or “screw axis” for ...
