Figure 1
(a) Patient 1: anteroposterior radiographs demonstrating eccentric placement of the femoral head within the acetabular polyethylene and excessive acetabular component abduction. (b) Patient 1: direct lateral radiograph demonstrating anterior femoral head subluxation and excessive acetabular component anteversion. (c) Patient 1: anteroposterior radiographs demonstrating concentric femoral head positioning and corrected acetabular component abduction. (d) Patient 1: direct lateral radiograph demonstrating concentric femoral head positioning and corrected acetabular component abduction.
