Figure 1.

A 75-year-old man with hip pain and suspected complications of a total hip arthroplasty. (a) A tomosynthesis section through the middle of the hip prosthesis, showing an improved delineation of the osteolysis around the cemented cup, especially the large erosion medial to the cup (arrows). (b) The AP radiograph does not display the osteolysis to full advantage. (c) The cross-table lateral radiograph shows the osteolysis anterior and posterior to the cup (arrowheads), which cannot be appreciated neither with tomosynthesis nor on the AP radiograph.
