Abstract

painful cervical hemangioma. Since then, there has been an explosion of interest in this remarkable procedure, which can be useful for the majority of vertebral fractures throughout the spinal column. This procedure is indicated for painful vertebral compression fracture(VCF) due to osteoporosis or malignancy, and for painful hemangiomas.
Vertebroplasty is the injection of bone cement, generally polymethylmethacrylate (PMMA), into a vertebral body (VB). Kyphoplasty is the placement of balloons into the VB, followed by an inflation/ deflation sequence to create a cavity prior to the PMMA injection. These procedures are most often performed in a percutaneous fashion under local anesthesia.
Although these methods are minimally invasive procedure, numerous complications can occur. The common complications include bleeding at the puncture site, PMMA leakage, local infection, and adjacent vertebral body fracture. A grave complication, which is rarely reported, is pulmonary embolism by PMMA leakage.
These procedures can reduce pain in about 90% of patients with osteoporotic VCFs. Additionally, improvements in mobility and in activities of daily living occur. The success rate is slightly less in patients with metastatic VCFs than osteoporotic VCFs. Much evidence favors the use of these procedures for pain associated with the aforementioned disorders. The risk/benefit ratio appears to be favorable in carefully selected patients.
This article summarizes the indications, techniques, complications and outcomes for the vertebroplasty and kyphoplasty.
