Reconstruction with β-tricalcium phosphate for giant cell tumor of the talus.

Giant cell tumor of bone (GCTB) is a locally aggressive tumor, commonly occurs in the long bones, and is rare in the talus and the foot. The talus is a weight-bearing bone and strut reconstruction is preferred. Reconstruction with low porosity β-tricalcium phosphate (β-TCP) blocks is reported for GCTB in the knee. In the current report, a 25-year-old female suffered from GCTB in the talus extending to the subchondral bone. The tumor was treated by curettage and the bone was reconstructed with low porosity β-TCP blocks, which have strong compressive strength. The implanted β-TCP blocks were incorporated successfully. The current reconstruction method can be applied for GCTB in the talus.
