Finite element models have been widely employed in an effort to quantify the stress and
strain distribution around implanted prostheses and to explore the influence of these …

Sinus lifting is performed with a variety of materials and techniques without a precise
knowledge of the quantity of augmentation. This study based on three‐dimensional finite …

Failure of an orthopaedic fixation due to stress shielding and consequent screw loosening is
a major concern among surgeons: the loosened screws could not only interfere with the …

Progressive loosening of bone fixation screws is a well-documented phenomenon, induced
by stress shielding and subsequent adaptive bone remodeling which results in bone loss …

This work presents a computational model for bone remodelling around cementless stems.
The problem is formulated as a material optimisation problem considering the bone and …

Although the revision rates for modern knee prostheses have decreased drastically, the total
number of revisions a year is increasing because many more primary knee replacements …

Periprosthetic adaptive bone remodelling after total hip arthroplasty (THA) has been
frequently simulated in computer models, combining bone remodelling theory with finite …

In this study, the finite element method (FEM) is employed to describe the strain situation in a
model of the human femur under a number of loading conditions. Two three-dimensional …

The present thesis is based on investigations performed at Orthopaedic Research
Laboratory, Department of Orthopaedics, Aarhus University Hospital, Denmark, and at …

Although cemented total hip replacement (THR) is a very successful surgical procedure,
high revision rates are occasionally reported for hip implants that are introduced on the …
