ResumoThe purpose of this study is to determine the validity and limitation of the percutaneous transpedicular biopsy of the vertebral body. Eighteen cases of transpedicular biopsies were performed between 1991 and 2001. All patients were placed in prone position and the biopsies were performed under local anesthesia. Trephine needle of 3 or 4 mm in outer diameter was inserted into the vertebral body under fluoroscopic guidance. Pathological diagnosis was succesful in 13 out of 18 cases. These diagnoses consisted of pyogenic spondylitis in 5 cases, metastatic vertebral tumor in 4 cases, compression fracture in 3 cases, and hemangioma in 1 case, whereas accurate diagnosis was not possible in 5 cases. The accuracy rate of this procedure was 72.2%. Although the percutaneous transpedicular biopsy is safe, rapid, and easy to bring the needle to the target site, considerable care should be taken to obtain adequate samples for accurate diagnosis.
