We performed this study in order to analyze the surgical and oncological results of prosthetic reconstruction of the distal tibial or fibular tumors and estimate the effectiveness of this kind of reconstruction in that region.

The data of six patients who underwent prosthetic reconstruction for the distal tibial or fibular tumors were reviewed. Diagnoses were osteosarcoma in four patients, parosteal osteosarcoma in one and recurrent giant cell tumor in one. Five tumors occurred at the distal tibia and one at the distal fibula. The age was 26 years (11-46 years). We performed resection and reconstruction using custom made tumor prosthesis. The mean follow-up duration was 5.8 years.

Average functional score by ISOLS evaluation system was 24.2 (80.5%). All of the patients were continuously disease free at the final follow up. The complications were one wound infection and one collapse of talar component.

The results of prosthetic reconstruction in the ankle regions demonstrated acceptable medium term results. It may be considered an option for malignant tumors of the distal tibia or the distal fibula in selected patients.
