Three-dimensional Printed Endoprosthesis for Reconstruction of the Distal Tibia and Ankle Joint After Tumor Resection.

Below-knee amputation is the treatment of choice for distal tibia malignancies, considering the specific anatomic features of the distal leg and ankle. However, advances in imaging modalities and adjuvant therapies and improved surgical techniques have made limb salvage surgery increasingly possible. The distal tibia is an uncommon location for malignant bone tumors, and there is limited information about limb salvage and reconstruction. Currently, 3-dimensional printed implants may successfully address reconstruction challenges after tumor resection. We present a patient with high-grade osteosarcoma of the distal tibia who underwent limb salvage and distal tibia and ankle joint replacement with a 3-dimensional printed endoprosthesis.
