Radiographs of the left hip of a 46-year-old man with osteonecrosis of the femoral head (ONFH) after failure of the tantalum implant with conversion to total hip arthroplasty with ceramic-on-ceramic bearing. a Pre-operative radiograph. b Radiograph at 1-year, postoperatively, shows no osteolysis. Tantalum debris can be observed in the proximal, middle and distal regions (black arrows). c An anteroposterior view of the left hip at two years after total hip arthroplasty reveals a well-defined sclerotic edge near the medulla of the greater trochanter (black arrow). d Radiograph at four years, postoperatively, shows that the acetabular and femoral components are solidly fixed in a satisfactory position, with the radiolucencies in zones 1 and 7. e Radiograph at six years, postoperatively, shows no evidence of prosthesis loosening. The Harris score was 93 points at the last follow up
