Lengthening of intercalary allograft combined with free vascularized fibular graft after reconstruction in pediatric osteosarcoma of femur.

Abstract

Involvement of the growth plate by a tumor or an injured growth plate during surgical procedures causes a discrepancy in the limb length. To address this problem,distraction osteogenesis is a well-established procedure for the treatment of defect and leg length discrepancy inviable bone tissues. We present the lengthening of an intercalary allograft combined with a vascularized fibular graft after reconstruction of osteosarcoma in the femoral metaphysis of a 10-year-old boy. The ability to lengthen through a composite allograft-vascularized fibular graft would add another option for reconstruction in skeletally immature children after resection for bone sarcomas.
