Giant-cell tumor of bone in the distal radius. Plain radiographs have an osteolytic and expansive lesion (A). Shaped iliac cortical bone is put on both sides of the wrist, and a beta-TCP block with high compressive strength is put between the autografts. Kirschner wires are used for fixation (B). Complete incorporation was seen 14 months after the operation (C).

A plain radiograph showed an expansive and ill-defined osteolytic lesion involving the distal epiphysis of the radius (Fig. 1A). Cuneiform shaped beta-TCP blocks were placed between the autografts (Superpore hard-type: Department PENTAX New Ceramics Division HOYA Corporation) and fixed with Kirschner's wires (Fig. 1B). Local recurrence was not observed on follow up fourteen months after the operation, and complete incorporation of the graft was seen (Fig. 1C).
Giant-cell tumor of bone in the distal radius. The lesion has homogeneous low-signal intensity on a T1 weighted image (A) and heterogeneous intermediate and high signal intensity on a T2 weighted image with (B) and without (C) fat-suppression on MRI. CT images show an expanded but thin cortex (D).

Magnetic resonance imaging (MRI) of the lesion showed homogeneous low-signal intensity on a T1 weighted image and heterogeneous intermediate and high signal intensity on a T2 weighted image (Fig. 2A-C). Computed tomography (CT) failed to detect the cortex at the flexor, radial or dorsal sides of the lesion (Fig. 2D).
