[Percutaneous cementing techniques in treatment of osteoporotic spinal sintering].

During the last years minimal-invasive augmentation techniques of vertebral bodies have been established to stabilize painful height losses. A vertebroplasty fills the vertebral body with cement, whereas a kyphoplasty intends to achieve a reduction of kyphosis prior to cementing. The present review describes both techniques and summarizes in vivo and in vitro experiences.
