case_images: Lauenstein view of the right hip immediately after surgery (a) and at 2 (b), 4 (c), 6 (d), 8 (e), and 10 (f) years after surgery. After 4 years, acetabular osteolysis developed in zones 1 and 2 (black arrow heads), and the lesion was most significant at 6 years after surgery. However, most of the osteolytic area had been replaced by newly formed bone at 10 years (white arrow heads) without evidence of implant loosening.

case_images: THA, major acetabular osteolysis developed in his right hip in Delee and Charnley zones 1 and 2 (Figure 3(c)), whereas no osteolytic change was observed in the left side. The osteolytic change was most significant at 6 years after surgery (Figure 3(d)). Finally, most of the osteolytic area had been replaced by newly formed bone at 10 years (Figure 3(f)).
