PVP (Percutaneous
PVP (percutaneous vertebroplasty) is a minimally invasive spine surgery technique that involves percutaneous injection of bone cement into the vertebral body through the pedicle or external pedicle under the fluoroscopic guidance of a C-arm X-ray machine to increase the strength and stability of the vertebral body, prevent collapse, relieve pain, and even partially restore the height of the vertebral body. PKP (Percutaneous kyphoplasty) is a minimally invasive spine surgery technique based on PVP.
PKP (Percutaneous kyphoplasty) is a further improvement on PVP, which also involves the percutaneous insertion of a bone expander (balloon) into the vertebral body under fluoroscopic guidance of a C-arm X-ray machine through the pedicle or extradural pedicle. The balloon expands to restore the height of the vertebral body and creates a cavity within the vertebral body that is used directly for the filling of the bone cement. In this way, the bone cement can be injected at low pressure, thus reducing the risk of leakage. It is a minimally innovative method for treating osteoporotic vertebral compression fractures in the elderly, which has the advantages of restoring vertebral body height, correcting spinal deformities, and reducing the risk of bone cement leakage, in addition to the advantages of minimal trauma and rapid pain relief.
