摘要

Purposes: We would like to inform the characteristics of recurred osteo-fibrous dysplasia (OFD), and also the possible use of vascularized composite autograft and allografts (VCA) combined with live fibular graft (LFG) for the treatment of aggressive benign bone tumor and osteogenic sarcomas in children. Materials and Methods: We reviewed one boy with recurred OFD after LFG, and other four children with osteogenic sarcoma in long bone which was treated with LFG and VCA, and followed them for average 9 years (3 - 14 years). Survival of the LFG and VCA was estimated by the ISOLS Functional Radiologic Scoring System, but not with Kaplans-Meier’s scoring system because of a small series of case reports. Results: All succeed after surgeries initially, but the cause of recurrence of OFD was still unclear, and one girl with osteogenic sarcoma on distal femur died with skip and lung metastasis, 4 years after surgeries. Conclusions: The causes of recurred OFD are not found thru pathologic studies of our patient, but we believe the multifocal origin of tumor cells even on the adjacent soft tissues in OFD is one of the causes. The excised long bone tumor is recycled by pasteurization or autoclaving, or allograft, then LFG, and neo-adjuvant chemotherapy would be one of elective surgery for the treatment of malignant long bone tumors in children. The LFG into recycled autograft or allograft bone is difficult to perform simultaneously, but very effective to increase more earlier regenerative vascularities and also the stabilities of the dead bones in children.
