title: Acetabular osteoarticular allograft after Ewing's sarcoma resection.
abstract: Ewing's sarcoma of the pelvis traditionally has been a difficult problem in orthopaedic oncology. Multiple studies have had inferior outcomes when compared with outcomes of patients with similar stage disease involving only the extremities. A major reason for this discrepancy is the difficulty associated with resection and reconstruction of pelvic tumors. Often the tumors are deemed nonresectable and are treated with chemotherapy and radiation or radiation alone. Patients treated in this manner have lower 5-year survival rates, higher local recurrence rates, and multiple long-term complications. The case of a 4-year-old girl with Ewing's sarcoma of the left hemi-pelvis is reported. Combined with adjuvant chemotherapy, this patient was treated with resection followed by osteoarticular allograft reconstruction. At 2 years followup, the patient was disease-free with an excellent functional outcome.
