The so-called PKP surgery refers to a minimally invasive surgery for lumbar spine related diseases. For example, when a patient has a compression fracture of the lumbar spine or a pathological fracture caused by severe osteoporosis of the lumbar spine, such minimally invasive treatment can be used to quickly relieve the patient of a series of symptoms such as lumbar pain and adverse lumbar movement. The main principle of this procedure is to locate the diseased lumbar vertebrae by using some radiological means on the surface of the body, then use special surgical instruments to access the diseased vertebrae directly on the surface of the skin, and then use a balloon to prop up the vertebrae and restore them to their original height and shape. At this point, bone cement can be injected into the resulting defects and cavities. Once the cement is injected into the vertebral body, it sets rapidly, resulting in a very stable strength. At this point, the patient can regain the shape of the spine and have a very stable spine. These patients often have a very rapid recovery after surgery.
