    Abstract:
    Twenty-five patients underwent an internal hemipelvectomy with endoprosthetic reconstruction of the pelvis for primary bone tumor (n = 17) or bone metastasis in the pelvis (n = 8). According to the Enneking tumor classification system, there were 9 stage II B tumors and 16 stage III. Conventional metal or polyacetal prostheses were used in 5 cases, and in 20 anatomically adaptable modular prostheses with intramedullary anchorage were implanted. In the last 11 cases a 3D CT-controlled manufactured model of the pelvis was used. The functional results according to Enneking were good in 5 cases, fair in 11, and poor in 7. The last endoprosthetic system showed better results, because it is easier to implant and the possibility failure is reduced. The learning curve of the surgeon is important, too.
