Kyphoplasty and vertebroplasty.
Percutaneous vertebroplasty is the injection of a vertebral compression fracture (VCF) with bone cement, generally polymethylmethacrylate. Percutaneous kyphoplasty is the placement of balloons into the vertebral body with an inflation/deflation sequence to create a cavity before the cement injection. These procedures are most often performed in a percutaneous fashion on an outpatient (or short stay) basis. The procedure is indicated for painful VCFs due to osteoporosis or malignancy, and painful hemangiomas. The procedure may have efficacy in painful vertebral metastasis and traumatic compression fractures. Much evidence favors the use of this procedure for pain associated with these disorders. The overall risks of the procedure are low, but serious complications (including spinal cord compression) can occur. With good patient selection and careful technique, these complications are avoidable, making the risk-to-benefit ratio highly favorable.
