Kyphoplasty and vertebroplasty are used to treat painful vertebral compression fractures in the spinal column, to stabilize the bone, and to restore some or all of the lost vertebral body height due to the fracture. Such fractures are a common result of osteoporosis and can be secondary to injury, or a tumor.
During a vertebroplasty/kyphoplasty procedure, a small incision is made in the back through which the doctor places a narrow tube using imaging guidance ensuring the correct position. The tube creates a path through the back into the fractured area through the pedicle of the involved vertebrae. Your doctor may inject a cement-like material called polymethylmethacrylate (PMMA) into the fractured bone (vertebroplasty) or insert a balloon into the fractured bone to create a space and then fill it with cement (kyphoplasty). This pasty material hardens quickly, stabilizing the bone. Following vertebroplasty, about 75 percent of patients regain lost mobility and become more active.
