As the average human life span increases and the aging population increases, the incidence of osteoporosis is increasing year by year. Clinically, there are often elderly people who suffer fractures from very small external forces due to osteoporosis. Osteoporotic fractures are especially common in thoracolumbar compression fractures, a disease that seriously affects the mobility and quality of life of the elderly. The traditional treatment methods are long-term bed rest, brace fixation and drug therapy, but it is difficult to relieve the stubborn back pain and cannot restore the vertebral height (such as hunchback deformity), and the reduction of activity after long-term bed rest further leads to osteoporosis, bone loss and bone strength, which may cause fracture to occur again. Percutaneous vertebroplasty, a minimally invasive surgical method carried out in recent years by the Orthopedic Column Surgery Department of the Second City Hospital, is gradually becoming the main means of treating osteoporotic fractures as it can instantly relieve patients’ low back pain and provide early functional exercise out of bed. The procedure is performed by making two 5-mm incisions in the skin of the low back, inserting a small sleeve into the diseased vertebral body under a C-arm fluoroscope, and then using a special vertebral body repositioner to enter the fracture site along the sleeve to open and reposition the fracture, and injecting a strengthening agent (commonly known as “bone cement”) into the vertebral body, thus achieving the effect of strengthening the vertebral body. The strengthening agent (commonly called “bone cement”) is injected into the vertebral body to strengthen the vertebral body. The procedure usually takes only about half an hour, and local anesthesia is sufficient. The procedure itself has very little effect on the elderly patient’s body, and the back pain disappears immediately after the procedure.
