Seventy-one percutaneous transpedicle biopsy specimens were taken from 68 patients with cervical, thoracic, lumbar, or sacral vertebral lesions, with the patients under local anesthesia. Sixty-one procedures were done with fluoroscopic guidance and seven procedures were done with computed tomography guidance. Twenty-one patients were diagnosed as having infectious spondylodiscitis, three had tuberculosis, two had coccidiomycosis, two had brucellosis, one had blastomycosis, one had an echinococcus cyst, six had primary neoplasms, 14 had metastatic neoplasms, five had osseous repair for insufficiency fractures, seven had osteoporotic fractures, and one had Paget's disease of bone. In the four remaining patients, the biopsy initially was negative but it was proven to be false-negative because of faulty biopsy technique. The percutaneous transpedicle approach for biopsy is safe, efficacious, and cost-effective. False-negative results and complications can be avoided when adhering to the technical details of this procedure.
