For malignant (malignant) tumors, one strives for removal in healthy tissue with a safety margin.
The following form of surgical therapy is available:
- Wide resection – method of choice for malignant (malignant) bone tumors.
- Procedure: wide and radical resection (surgical removal) of the tumor with a safety margin of 5 cm (proximal (toward the center of the body) and distal (away from the center of the body)).
- After tumor removal, an osteosynthesis (insertion of a spongiosaplasty) or a reconstruction of the resulting bone defect, for example, in the form of a tumor endoprosthesis, a bone graft or muscle, nerve and vascular replacement plastics.
- Through the use of megaendoprostheses, amputations of the affected limb are rarely necessary (“Ultima ratio” (last resort)).
In the case of dedifferentiated (highly malignant/very malignant) chondrosarcoma and joint involvement, amputation may be necessary.
