Vertebroplasty for the treatment of vertebral compression fractures (VCFs) was introduced in the United States in the early 1990s. The procedure is usually done on an outpatient basis, although some patients stay in the hospital overnight. The procedure may be performed with a local anesthetic and intravenous sedation or general anesthesia.
Using x-ray guidance, a small needle containing specially formulated acrylic bone cement is injected into the collapsed vertebra. The cement hardens within minutes, strengthening and stabilizing the fractured vertebra. Most experts believe that pain relief is achieved through mechanical support and stability provided by the bone cement.
Vertebroplasty typically takes about 1 to 2 hours to perform, depending on the number of vertebrae being treated.
Kyphoplasty is a newer approach to treating vertebral compression fractures.

Complication rates for vertebroplasty and kyphoplasty have been estimated at less than 2 percent for osteoporotic VCFs and up to 10 percent for malignant tumor-related VCFs.
