Percutaneous vertebroplasty: current concepts and local experience.
With the aging population in our country, symptomatic osteoporotic compression fractures are increasingly common. Osteolytic compression fractures from spinal metastasis are also becoming more frequently seen because of the longer life expectancy from improvements in chemotherapy. Percutaneous vertebroplasty with PMMA has been shown to be an efficient procedure to treat pain due to these fractures. It is a minimally invasive procedure performed under local anesthesia and sedation. Injection of PMMA provides immediate stability when it hardens, and permits the patient to ambulate without pain. Appropriate patient selection is the key to clinical success. However, this procedure must be treated with respect, and has to be performed by physicians with the necessary training. Otherwise, increased pain, paralysis, and even death may occur from this seemingly innocuous procedure. In this article, I will deal with the background issues of osteoporotic and osteolytic vertebral compression fractures, patient selection, surgical technique, complications, and review of current literature on vertebroplasty. Key areas of development in this field include the use of kyphoplasty, defining the role of prophylactic augmentation, and improvements in biomaterials.
