This book presents analyses of the most commonly reported failure modes of hip stems: loosening
and thigh pain both are attributed to the relative motion and instability at the bone-implant
interface due to failure to achieve sufficient primary fixation. The book investigates various
factors that could affect primary stability and therefore the long-term outcome of hip
arthroplasty. The results complement experimental work carried out in this area as in-vitro
experiments have several limitations that could be addressed through computer simulations.
