A Geometric Model to Determine Patient-Specific Cup Anteversion Based on Pelvic Motion in Total Hip Arthroplasty

<div>Solid modeling of pelvis, cup and vectors generated by changing pelvic tilt (rotation in sagittal plane). Red lines = vectors normal to the flat cup surface. Blue lines = red lines projected onto the axial plane representing functional anteversion.</div>
