Abstract:
Percutaneous vertebroplasty (PVP) and kyphoplasty (PKP) are perf or med by image-guided spinal procedures and consists in percutaneously transpedic ular injection of the polymer polymethylmethacrylate (PMMA) into a fractured ver tebral body to relieve the pain and to strengthen the bone. Advantages of the te chnology include its relative simplicity, fewer complications and minimally inva sive surgery. PKP can also restore vertebral height. This paper is to sum up the results of biomechanical comparison of different cements, different volumes and different distribution in the vertebras. This article also indicates the disadv antages of PVP and PKP at present. To achieve the goal in the future, the operat ions and ideal biomaterials should be improved and developed.
