Introduction:
Giant cell tumor of bone is a locally aggressive tumor. Preserved joint reconstruction for tumors in the distal radius is challenging, especially when there is extraosseous extension and less subarticular bone.
Presentation of case:
To preserve the joint, we developed a new reconstruction technique using β-tricalcium phosphate (TCP) with strong compressive resistance.
Discussion and conclusion:
Giant cell tumor of bone in the distal radius was treated by curettage and bone grafting, plus the use of β-TCP. This new method will preserve joint junction.
