What is vertebroplasty

Vertebroplasty is the percutaneous injection of polymethylmethacrylate (PMMA) into a vertebral body to provide stabilization and relief of pain. The procedure was introduced in the 1980s, initially for treatment of vertebral hemangiomas. Currently, the procedure is most commonly used to treat acute and subacute osteoporotic vertebral body compression fractures. The procedure is performed with local anesthetic, with or without intravenous sedation, or with general anesthesia. The patient is placed prone on a radiolucent table and positioned to optimize fracture alignment. High-quality, high-resolution fluoroscopy is required and biplane fluoroscopy is preferable. Following placement of a needle into the vertebral body through either a pedicular or extrapedicular approach, bone cement mixed with barium contrast is introduced into the vertebral body with fluoroscopic monitoring. Multiple small syringes are commonly used to introduce the PMMA into the access needle. Alternatively, use of a remote cement delivery system permits the operator to stand away from the fluoroscope and needle to decrease radiation exposure to the operator. The typical amount of cement injected varies from 2 to 4 mL for thoracic vertebrae and 4 to 8 mL for lumbar vertebrae (Fig. 66-2).
