CT guided injection of bone cement vertebroplasty (PVP/PKP) is an effective treatment for osteoporosis with vertebral compression fractures, vertebral tumors, and bone metastases. Basic principle: Osteoporosis accompanied by vertebral compression fractures and tumor metastasis are both stubborn pains. Under CT guidance, percutaneous puncture is performed to inject polymethylmethacrylate (PMMA) into the affected vertebral body, increasing the compressive strength of the vertebral body and improving spinal stability. Through the aggregation heat effect of the bone cement, the pain nerve endings undergo degeneration and necrosis, cutting off tumor blood supply, causing thermal damage to tumor tissue, stabilizing microfractures to alleviate or eliminate pain, and preventing the development of vertebral collapse.
