Abstract:
Two patients with painful lytic lesions of the vertebral pedicle were treated with percutaneous pediculoplasty. This technique, similar to vertebroplasty but with increased procedural risks because of the immediate vicinity of neural structures, was performed under high-quality biplane fluoroscopic guidance. For lesions involving both the pedicle and the vertebral body, a double-needle unipedicular technique is advocated.
