Pelvic limb-salvage surgery for malignant tumors

Thirteen patients with primary malignant tumors of the pelvis underwent int ernal hemipelvectomy. The diagnoses were: Ewing's sarcoma 7, osteosarcoma 4 , chondrosarcoma 1, and malignant fibrous histiocytoma 1. No megaprostheses or massive allografts were used for reconstruction. Six patients underwent resection only with no reconstruction, 5 had strut grafts inserted to rest ore the pelvic ring, 1 had an autoclaved autograft of the acetabulum and 1 had an ilio-femoral arthrodesis. No patients were lost to follow-up. Nine p atients died from their disease after an average of 23 months (range 2 to 7 2 months). The 4 survivors (3 free of disease) have an average follow-up of 84 months (range 60 to 120 months).
