[Clinical data on the frequency, localization, and surgical therapy of bone tumors (author's transl)].

Between 1973 and 1978 a total of 77 patients suffering from a tumor of bone were treated and followed up at this hospital. Of these patients, 52 were found to have benign tumors and pathologic tumorlike changes of bone. 25 were found to have semimalignant and malignant tumors. This paper describes localisation of bening semimalignant and malignant tumors of bone by means of a modified WHO-classification. The surgical treatment of different bone tumors is discussed on the basis of special cases.
