TL;DR: The paper focuses on the loading of the femoral implant component but complete data are additionally stored on an associated compact disc that contains complete gait and hip contact force data as well as calculated muscle activities during walking and stair climbing and the frequencies of daily activities observed in hip patients.

TL;DR: In one hip in the first patient and in the second patient the direction of large forces approximated the average anteversion of the natural femur, so the joint loading was observed over the first 30 and 18 months, respectively, following implantation.

TL;DR: In general, resultant contact forces during dynamic activities were lower than the ones predicted by many mathematical models, but lay in a similar range as measured in vivo by others.

TL;DR: Three-dimensional, nonlinear finite element model of the L3/L4 functional unit was used to study the influence of disc degeneration on motion segment mechanics and found that a mildly degenerated disc increases intersegmental rotation for all loading cases.

TL;DR: A method was developed for calibrating the two-composite structure of the annulus fibrosus, the ground substance and collagen fibers to fulfil the required range of motion obtained from in vitro results within an accuracy of 99%.
