Treatment outcome of pelvic sarcomas in young children: Orthopaedic and oncologic analysis

Five children with pelvic Ewing's sarcoma whose age was 6-10 years underwen t reconstruction after resection of the tumor. One child with a tumor of th e ilium underwent an iliosacral arthrodesis with allograft. Three patients underwent a hip transposition after the resection of the ilium and the uppe r part of the acetabulum. One patient underwent no skeletal reconstruction after the resection of the acetabulum and the ilium. Two children are alive 96 and 60 months after surgery: however, two died 12, and 21 months after surgery of metastasis, and one is alive with metastasis 15 months after sur gery. Functional evaluation was possible in four patients: one is excellent , and three are fair. After resection of the ilium, including the upper par t of the acetabulum, a hip transposition can be selected. If all the acetab ulum is resected, it will be optimal not to do a bony reconstruction.
