Abstract

Pelvic bone sarcomas present a challenging therapeutic problem in terms of local control and survival. The most common sarcomas in the pelvis are chondrosarcomas, Ewing's sarcomas, and osteosarcomas. The prognosis is much less favorable than for patients with more distally located tumors. The ability for limb salvage pelvic reconstructions has increased with advances in imaging and surgical techniques and instrumentation. Reconstruction options have also evolved. before the 1970s, most tumors arising from the bone pelvis were surgically treated with hemipelvectomy with amputation of the limb that was resulting in marked functional and gait disability. Compared to the present, the planning tools and imaging techniques used at that time seem archaic: magnetic resonance (MR) imaging did not exist and computed tomography (CT) was a rather new technique. In the meantime, both diagnostic preocedures have greatly improved and made possible to define the exact extent of a tumor and its relation to functionally important structures such as nerves and blood vessels, and intestinal organs. Currently, the development of new techniques in oncologic reconstruction especially of tumor prostheses made possible limb salvage pelvic resections and reconstructions as alternatives to hemipelvectomy and resection-arthrodesis. However, pelvic surgery for sarcomas remains difficult and challenging because of the complexity of pelvic anatomy and the extent of tumor growth; reconstructions also remain difficult, especially when the acetabulum is involved, and complications are often.
