[Advances in the diagnosis and therapy of bone tumors with special reference to modern surgical possibilities]

Progress in the diagnosis of bone tumors is primarily to be seen in the possibilities of exact radiological demonstration, the differentiation of morphological characteristics of tumor growthdynamics (tumor vessels) and in the possibilities of modern nuclear methods, which provide preoperative information on the metabolism of the tumor. Remarkable progress could be achieved regarding therapy especially with surgical measures, as combined osteosynthesis and alloplastic, as well as in the development of improved materials for implantation (metal, plastic, cement) and improvement of implantation itself. The implantation of extensive amounts of foreign material in the modern ultrasterile operating rooms with horizontal or vertical flow is today possible with greater safety. In the combination of orthopaedic surgery and cytostatic and immunotherapy there exist today greater chances in the treatment of malignant bone tumors.
