Implanted β-Tricalcium Phosphate Blocks Can Function as a Placeholder in Recurrent Giant Cell Tumor of Bone

Figure 2

Giant cell tumor of bone in a 25-year-old female. The lesion has homogenous low-signal intensity on T1-weighted images (a). The implanted β-TCP is gradually remodeled and incorporated at 3 months (b) and 8 months (c) after the operation. Osteolysis is predominantly observed in β-TCP blocks in plain radiographs (d) and a CT image (e) 2 years and 5 months after the operation. The subchondral bone is preserved (f).
