Abstract:
PURPOSE: This study was designed to verify intermediate-term functional and radiological results of limb salvage operation using endoprosthetic replacement system (MUTARS(R)) used in patients with a malignant bone tumor. MATERIALS AND METHODS: Thirty one cases which used MUTARS(R) tumor prosthesis were reviewed. The mean age of the patients was 49.2 years and the mean follow up was 39.8 months. We retrospectively reviewed complications, and evaluated functionally and radiologically by Enneking functional score, ISOLS radiological implants evaluation system at last follow-up. RESULTS: 3 patients had died of disease, distant metastasis was seen in 4 patients and local recurrence was seen in 1 patients. Complications were developed in 12 patients. (infection 6, leg length discrepancy 2, aseptic loosening 2, periprosthetic femoral fracture 1, screw loosening 1) Mean value of total functional scores were 81.2% in proximal femur, 77.4% in distal femur, 78.1% in proximal tibia, and 80.2% in proximal humerus. The overall radiological result was relatively satisfactory. CONCLUSION: Our results suggest limb salvage with the MUTARS(R) endoprosthesis is successful with good functional and radiological results. But we should be careful with complications such as infection.
