The structure of the femoral neck: A physical dissection with emphasis on the internal trabecular system

It is accepted that the formation of these trabeculae, and their retention with age, is due to the forces acting through them. The findings of the study, however, suggest that the horizontal trabeculae are responsible primarily for the conduction of compression forces, rather than tension forces as described in the Trajectorial Theory. A suggestion as to how the compression forces may be conducted through both these columns in the upper femur is given in light of the findings. These concepts, if proven, may require a modification of the approach to the biomechanical analysis of this region, particularly when using the various imaging techniques, as well as with physical testing of prostheses and other such hip devices.
