[Rotationplasty in the surgical treatment plan of primary malignant bone tumors. Possibilities and limits].

Long-term survival of patients with a malignant bone tumor increased with a combined therapeutic approach using chemotherapy and possibly radiation therapy. Today up to 80% of patients with an osteosarcoma or Ewing's sarcoma survive. Therefore, it is important that the functional outcome and the quality of life are good after resection of the tumor. Before the era of endoprosthetic devices, rotationplasty, which was introduced in 1974 by Salzer for surgery of malignant bone tumors and modified by Winkelmann, protected many patients from an amputation. Although many authors favor limb-saving procedures today, rotationplasty obtained excellent functional and psychosocial results. Rotationplasty can be recommended in tumors with a large soft tissue component, in tumors located in the proximal femur and proximal tibia, and in children under 10 years of age. Furthermore, rotationplasty can be used in patients in whom a limb-salvage procedure failed because of infection or repeated changes of the endoprosthesis.
