206 patients with tumorendoprosteses of the KMFTR-type at the lower extremity were operated at the Institute Rizolli Bologna and at the University Clinic of Vienna. The minimum follow up was 2 years (mean 3.2, max. 8 years). In order to bridge the defect caused by tumor resection the proximal femur was replaced in 42 cases, the distal femur in 119 cases and in 6 patients a total femur prosthesis was used. The proximal tibia was replaced in 35 cases and in 4 cases a total knee prosthesis was implanted. Clinical evaluation according to Enneking revealed 71.6% excellent and good results. In 83.4% the radiological score was higher then 20. We saw deep infections in 8.2% (17 patients), breakage of the prosthesis in 6.8% and aseptic loosening in 5.8%. 3 patients had to be amputated due to infection. In the remaining cases of infection in 66% of the patients healing was observed. All cases of aseptic loosening or breakage could be revised successfully by an exchange of the prostheses and therefore salvage of the leg was achieved.

Abstract
206 patients with tumorendoprosteses of the KMFTR-type at the lower extremity were operated at the Institute Rizolli Bologna and at the University Clinic of Vienna. The minimum follow up was 2 years (mean 3.2, max. 8 years). In order to bridge the defect caused by tumor resection the proximal femur was replaced in 42 cases, the distal femur in 119 cases and in 6 patients a total femur prosthesis was used. The proximal tibia was replaced in 35 cases and in 4 cases a total knee prosthesis was implanted. Clinical evaluation according to Enneking revealed 71.6% excellent and good results. In 83.4% the radiological score was higher then 20. We saw deep infections in 8.2% (17 patients), breakage of the prosthesis in 6.8% and aseptic loosening in 5.8%. 3 patients had to be amputated due to infection. In the remaining cases of infection in 66% of the patients healing was observed. All cases of aseptic loosening or breakage could be revised successfully by an exchange of the prostheses and therefore salvage of the leg was achieved.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
