Femoral Expandable Prosthesis In Bone Tumor of an Adult: A Case Report

Management of bone tumors of the limbs is still a field to be explored. The problems to be faced are diff erent, especially when the lower limbs are the point of interest, due to the diff erent leg length residual. A possible solution, provided by new technologies, is the use of electromagnetic expandable prosthesis. This device is successfully used in the management of paediatric malignant bone tumors. The strength of this prosthesis is the possibility to assist the musculoskeletal growth in children. To our acknowledge review of literature points out only few cases in which this mechanism is used in adult population. The authors present their results with expandable endoprosthetic replacement in an adult patient with severe lower limb discrepancy which occurred after a malignant bone tumor of the knee, obtaining a recovery of approximately 6 cm.
