Minimally invasive percutaneous vertebroplasty is mainly used for osteoporotic vertebral compression fractures and bone tumors to: ① restore or preserve adequate neurological function ② relieve pain; ③ ensure immediate or permanent spinal stability. Percutaneous Vertebroplasty (PVP) Percutaneous kyphoplasty (PKP), is mainly used for pain and vertebral compression fracture caused by vertebral metastatic tumors, myeloma, lymphoma, hemangioma and so on. Artificial bone cement is injected into the vertebral body through the pedicle or directly into the vertebral body to enhance the strength and stability of the vertebral body and relieve low back pain. It is believed that pain relief can be achieved because the mechanical support of bone cement reduces the compressive stress on the vertebral body, and the chemical and thermal effects of bone cement may necrose the tumor tissue or destroy the nerve endings in the vertebral body and the surrounding tissues. In recent years, we have used minimally invasive percutaneous vertebroplasty to treat a large number of patients with vertebral compression fractures and vertebral metastatic tumors, especially those with multisegmental vertebral metastatic tumors that cannot be surgically resected because they do not yet have neurological impairment. After 2-3 years of follow-up investigation and study, it has obvious therapeutic effects on enhancing the strength and stability of the vertebral body and rapidly relieving low back pain, greatly improving the survival rate and quality of life of patients. Meanwhile, due to the minimally invasive operation, it has short operation time, minimal bleeding and high safety, and can be operated even for elderly patients.
