[Malignant fibrous histiocytoma after supracondylar femoral fracture (author's transl)].

Supracondylar slanting fracture of the femur was treated by osteosynthesis in a 14-year-old girl. Two months after removal of the plate and screws, 10 months after the initial trauma, a malignant bone tumour in the form of malignant fibrous histiocytoma was diagnosed at the same location after a renewed fracture. The preceding trauma may be assumed to be one of the reasons for occurrence of this rare tumour.
