Data on 20 patients with giant cell tumor of bone
Figure 1. Localization of main tumor components. 3 groups according to Enneking and Dunham (Citation1978). Region I: iliosacral area; region II: acetabular area; region III: ischiopubic area. 9 tumors affected region I, 6 affected region II, and 5 affected region III.

Figure 5. Case 11. a. After intralesional resection of a GCT of the ischium. Additional curettage and bone cement packing of the acetabular extension was performed. The cement was fixed with 2 screws to prevent dislocation. b. CT showing dislocation of the dorsal screw, necessitating surgical removal.
