[The treatment of bone lesions in myelomatosis (author's transl)]

41 patients suffering from a bone lesion due to myelomatosis were treated (32 multiple myelomata and 9 solitary myelomata). Diagnosis was established by biopsy in 9 cases. In 8 cases there was compression of the spinal cord or of a spinal root. 15 pathological fractures were treated by fixation and bony union was always obtained. In 7 other cases, fixation was used to prevent fracture and 2 patients had a total joint prosthesis. It is concluded that the treatment of the bony lesions of myelomatosis is comparable to that of bony metastases but the average survival is much longer.
