Vertebroplasty and kyphoplasty for the palliation of pain.

Vertebroplasty and kyphoplasty are percutaneous techniques developed over the past 20 years to treat vertebral hemangiomas, osteoporotic compression fractures, and osteolytic tumors of the spine. In carefully selected patients, these procedures have led to the cessation or significant reduction in pain in 80 to 90% of patients. In this article, we review the indications and contraindications of these procedures, appropriate patient selection and evaluation, the technique, outcomes, and the potential complications of this form of therapy when performed for the alleviation of pain for osteolytic tumors of the spine.
