AbstractVertebroplasty is a image-guided therapeutic procedure, consisting of an injection of acrylic cement through a bone biopsy needle into a vertebral body. Main indication for vertebroplasty is painful vertebral body compression fracture due to osteoporosis. The procedure is an efficient mean with high success in pain release and prevention of further collapse of the treated vertebrae; however, the technique does not allow to realign the spine. Kyphoplasty was designed to address the kyphotic deformity. It involves the percutaneous placement of an inflatable bone tamp into a vertebral body (VB). Restoration of VB height and kyphosis correction is achieved by inflation of the tamp with contrast material liquid. After deflation a cavity is created that eases the cement application. The most modern way of guidance in spinal surgery is neuronavigation--the use of frameless stereotaxy. The system reformats patient-specific CT images acquired prior surgery, performs image fusion with intraoperative plain X-ray. Before the operation, the surgeon may create surgical plan and simulate advancement of a virtual instrument along one or more surgical trajectories. During surgery, the system tracks the position of specialized surgical instruments. All three modalities mentioned above have been applied in the treatment of our patient suffered from multiple osteoporotic vertebral body compression fractures. Using kyphoplasty an almost total VB height restoration could be achieved. The pain relief was more than 50% after both operation.
