X-rays showed significant osteolysis of the proximal femur, distal to the greater trochanter of his left hip (Figure 1). Comparison to the current x-rays (Figure 1) revealed that the particle disease had expanded and significantly increased the endosteal lytic zone, it was also evident that the ceramic head had penetrated deeper into the acetabulum.
