Percutaneous Biopsy of Vertebrae and Ribs

Clinical and roentgenographic evidence of bone metastases is often sufficient to contra-indicate operation in cases of malignancy. Attempts to arrive at a conclusive diagnosis must of course be made should the signs in the skeleton be in any way atypical. The facilities now available for localization of pathologic changes by roentgen television screening make possible the introduction of instruments for the sampling of material. Tissue material was collected during videofluoroscopy in 17 patients with lesions thought to be vertebral metastases and in 17 patients with costal lesion. The technique is relatively simple and appears to be of considerable help in the establishment of a definite diagnosis.
