The authors report 26 cases of high-grade malignant tumors of the distal femur (23 osteosarcomas, 3 Ewing's tumors) submitted to rotation-plasty. The five-years actuarial survival rate (in the 23 cases of osteosarcoma) was 69% and there was no incidence of local recurrence. The following complications were observed: wound dehiscence (6 cases), arterial thrombosis (in 2 patients submitted to resection and vascular termino-terminal suturing), paralysis of the sciatic nerve (2 cases), delay in consolidation (2 cases), traumatic fracture of the neo-femur (3 cases). All of the complications were resolved favorably, 5 of these requiring surgical treatment (33%). Satisfactory functional results were obtained in all of the cases, except in one patient who had limitation of the ankle joint subsequent to vascular compartmental syndrome. On the basis of the oncological, functional and biomechanical results reported in this study and in the literature, the authors discuss current indications for rotation-plasty.
