Total femur replacement: primary procedure for treatment of malignant tumours of the femur.

We present our experience of treating patients with tumours involving the whole femur with excision and total femur endoprostheses over the last 30 years (1975-2005). There were 26 consecutive patients (14 men and 12 women). Average age was 40 years (14-82 years) at the time of surgery and 21 of the patients had primary malignant bone tumours with five having the procedure for metastases. 11 patients were still alive of which nine were free of disease at the time of review at a mean follow-up of 57 months (3-348). The overall patient survival at 10 years was 37%. The survival of patients with a primary localised tumour was 50% at 10 years. Revision of the prostheses was necessary in two patients (at 110 and 274 months) because of recurrent dislocation and aseptic loosening. Amputation was necessary in two patients but long term limb survival was 92% at 10 years. Nine patients alive with no evidence of disease had a mean MSTS functional score of 72%.
