Limb Salvage Procedure Using Affected Bone and Huckstep Intramedullary Rod for Invasive Soft Tissue Sarcoma of the Femur

We evaluated the preserved limbs of 2 cases reconstructed with affected bone and Huckstep intramedullary rod for invasive malignant fibrous histiocytoma (MFH) of the femur. Case 1, a 65 year old female, had 5×5cm mass contacting with the lateral side of the right femur. At surgery, the partially resected femur was treated with 70% alcohol and was osteosynthesized with the Huckstep rod. Case 2, 67 year old male, had 15×11cm mass invading the left femur. The tumor invaded bone, and was treated with intraoperative radiotherapy. The femur was then reconstructed using the Huckstep rod.Both cases were able to achieve full weight bearing gait within four months after surgery. This limb salvage procedure was useful for elderly patients with soft tissue sarcoma invading the long bones.
