For the treatment of lytic disease involving the pedicles of vertebrae in patients with metastatic disease, the authors performed percutaneous vertebroplasty by using an access route via the lysed pedicle. Fifty-one pedicles were treated in 32 consecutive patients. In all cases, a radiologically satisfactory filling of both the affected pedicle and the vertebral body was achieved. Clinically effective pain relief was obtained in 24 (75%) of 32 patients, and no clinical complications were observed.
