World Journal of Surgical Oncology 2010 8 39 http content 8 1 39 RESEARCH WORLD JOURNAL OF SURGICAL ONCOLOGY Open Access Analysis of limb function after various reconstruction methods according to tumor location following resection of pediatric malignant bone tumors Yukihiro Yoshida 1 Shunzo Osaka2 and Yasuaki Tokuhashi1 Abstract Background In the reconstruction of the affected limb in pediatric malignant bone tumors since the loss of joint function affects limb-length discrepancy expected in the future reconstruction methods that not only maximally preserve the joint function but also maintain good limb function are necessary. We analysis limb function of reconstruction methods by tumor location following resection of pediatric malignant bone tumors. Patients and methods We classified the tumors according to their location into 3 types by preoperative MRI and evaluated reconstruction methods after wide resection paying attention to whether the joint function could be preserved. The mean age of the patients was years Osteosarcoma was observed in 26 patients Ewing s sarcoma in 3 and PNET primitive neuroectodermal tumor and chondrosarcoma grade 1 in 1 each. Results Type I were those located in the diaphysis and reconstruction was performed using a vascularized fibular graft vascularized fibular graft . Type 2 were those located in contact with the epiphyseal line or within 1 cm from this line and VFG was performed in 1 and distraction osteogenesis in 1. Type III were those extending from the diaphysis to the epiphysis beyond the epiphyseal line and a Growing Kotz was mainly used in 10 patients. The mean functional assessment score was the highest for Type I 96 n 4 according to the type and for VFG 99 according to the reconstruction method. Conclusion The final functional results were the most satisfactory for Types I and II according to tumor location. Biological reconstruction such as VFG and distraction osteogenesis without a .
