Fig. 1.
Radiograph showing measurements made. A horizontal line was drawn across the bottom of the acetabular teardrops, and a line that connected the superior and inferior edges of the acetabular component was connected to this horizontal line to measure the angle of inclination. The polyethylene wear rates were calculated by measuring the shortest radius from the center of the prosthetic femoral head to a point on the outer surface of the acetabular cup. In this figure. Cup inclination in left hip (a1) is 61.50, and right (a2) is 54.50. Liner wear of left side(o-ó) is 4.191 mm, and right side is 2.921 mm.
