Fig. 3　Postoperative evaluation of implant alignment with three dimensional, CT-based software.

Coronal reconstruction（a）, oblique axial reconstruction of the femoral neck（b）, oblique sagittal reconstruction of the cup（c） shows 33° of cup radiographic inclination, 13° of radiographic anteversion, 15° of stem anteversion, and 27° of combined anteversion（postoperative templating in blue）. Three dimensional, canal filling analysis indicates that the edges along the square stem fit well in yellow and red.
