| One of the advantages of this definition of the pelvis segment is repeatability. The greater trochanter landmarks can be identified reliably on most subjects (including patients). The Iliac Crest marker is placed pragmatically (i.e. such that it is placed to have anatomical meaning). For example, the Iliac Crest marker is placed to ensure that the angle of the pelvis relative to the laboratory computed in Visual3D is the same as the clinical measure of pelvis tilt. This can be accomplished by placing the Iliac Crest marker along the Iliac Crest such that the position of the marker relative to the Greater Trochanter marker yields pelvis tilt. In the figure to the left the Iliac Crest marker is placed slightly anterior to the greater trochanter marker to yield a slightly forward leaning pelvis tilt.\\ | One of the advantages of this definition of the pelvis segment is repeatability.
