[Primary malignant bone and soft tissue tumors of the pelvis--oncologic and functional outcome].

Surgical treatment of primary malignant bone and soft tissue tumors involving the innominate bone has to be considered an extensive procedure with high incidence of complications. It requires the knowledge of different techniques of resection and reconstruction of bone, joints, soft tissue and intrapelvic organs, as well as a multidisciplinary management. Therefore, it should be limited to specialized centers. The best oncological and functional results can be achieved by continuity resection and pelvic reconstruction in low grade malignant bone tumors [1-3].
