title: Prosthetic reconstruction for tumors of the distal tibia. Report of two cases.
abstract: Prosthetic reconstruction in two patients with malignant bone tumors of the distal tibia was conducted. The diagnoses were metastatic bone tumor in one patient and low grade central osteosarcoma in another. The mean duration of follow-up was 5.5 years (3 and 8 years). Reconstruction was achieved using custom-made prosthesis (JMM, Japan Medical Materials), which replaced the distal tibia. In the patient with metastasis, local recurrence occurred 8 months after the primary surgery and the recurrent tumor was resected. Both patients were free from neoplastic disease at the latest follow-up. The average functional scores according to the system of the Musculoskeletal Tumor Society were 25 and 23. Custom-made prostheses allow an early return to functional weight-bearing without major complications. This technique provides a safe and effective method of stabilization for properly selected malignant tumors of the distal tibia.
