Recently, our spine surgery department has made another technical breakthrough by successfully treating two centenarians with minimally invasive osteoporotic vertebral fractures, and the patients were treated from lying in the hospital to walking out of the hospital in less than 5 days. Traditional treatment of osteoporotic vertebral fractures requires bed rest, painkillers and osteoporotic drugs, orthopedic devices and functional exercises, but the following problems exist: the fractured vertebrae cannot be well reset, which further increases the decalcification capacity of bone tissue and aggravates osteoporosis, causing pneumonia, bed sores, urinary stones and venous thrombosis of the lower extremities in the elderly. Increases mortality The minimally invasive treatment of osteoporotic vertebral fractures mainly utilizes the properties of bone cement and performs vertebroplasty. It can achieve strengthening of the vertebral body, maintenance of vertebral stability and relief of spinal pain. There are two minimally invasive methods, one is simple vertebroplasty (PVP) and the other is posterior kyphoplasty (PKP), which is mainly used in our department. The disadvantage of PVP is that it cannot restore the vertebral height and correct the kyphosis. It is difficult to control the flow of bone cement when it is injected directly into the vertebral cancellous bone under high pressure, so the leakage rate of bone cement is higher.
