Abstract
Aims: A series of pelvic bone tumors with special reference to innovative operative procedures were examined. Methods: The series consisted of all patients treated surgically for pelvic bone tumors between 1981–2001. Results: There were 65 benign and 120 malignant tumors. Of the 65 benign tumors most were only biopsied or resected. Reconstructive methods were needed 16 cases, mostly they were cysts in the acetabular region that were þlled with cancellous bone.
48 of the malignant bone tumors were more than just biopsied. 32 were only resected, four hemipelvectomies were performed. 12 resections with reconstruction were done, þve times with endoprostheses, three times with PMMA, three times with bone grafting and once with osteosynthesis. The endoprosthetic solutions included two large pelvic reconstructions. Two large defects in the posterior pelvic ring were reconstructed with autogenous þbular grafts.
Pelvic rings left open after resection were susceptible to fatigue fractures, these cases were all treated conservatively. Large anterior reconstructions were reinforced with meshes to prevent herniation. Conclusion: In selected cases good function and stability is possible after large pelvic ring resections
