All RSA analysis will be performed Computer Aided Design (CAD) based Roentgen Stereophotogrammetry Analysis (RSA).
The micro-motion results will be calculated and reported as translations and rotations along and about the three anatomic axes. The subsidence of the hip stem is included in the results. The motion of the femoral stem and acetabular cup will be described in relation to the marker beads placed in the proximal femur and acetabular bone during surgery respectively.
The first CAD based RSA examination (within 5 days and prior to weight bearing) serves as the reference baseline. All subsequent evaluations of micromotion are related to the relative position of the implanted medical device with respect to the bone (bone markers) at the time of the evaluation
