Clinical application of percutaneous vertebral kyphoplasty Osteoporosis is a common disease that affects about 200 million people worldwide each year, and many patients suffer from fractures, with the vertebral body being the most vulnerable site for fractures. After vertebral fracture, patients have severe low back pain, limited turning, sleep disturbance, and inability to stand and walk, which seriously affects the quality of life. Traditional treatment is bed rest plus medication for pain relief, but long-term bed rest can aggravate osteoporosis, and about 80% of patients are left with serious complications such as acute or chronic low back pain, hunchback deformity of the spine, deterioration of mental status, infection, deep vein thrombosis and organ failure. Orthopaedic surgeons were previously at their wits’ end when faced with these vertebral fractures of advanced age, institutional weakness, extensive underlying disease, severe osteoporosis, and severe pain. However, a minimally invasive technique, percutaneous kyphoplasty (PKP), which involves injecting bone cement into the diseased vertebral body after puncturing it with a bone puncture needle under fluoroscopic surveillance, can be used to solve this difficult problem. The main effect is to relieve or alleviate pain, strengthen the fractured vertebral body and prevent further compression and collapse of the vertebral body. The Department of Spine and Joint Orthopaedics, under the leadership of Director Fu Qin, started to overcome this technical challenge two years ago, and in 2013, Associate Professor Liuda declared this minimally invasive technology as a triple-new project, and after active theoretical preparation and clinical practice, a number of PKP surgeries have been successfully performed. Happily, all patients in this group had pain relief after surgery, and they could walk normally on the first day after surgery, and they were discharged from the hospital on the second day after surgery. In addition, this surgery is performed with local anesthesia, small incision (5 mm), low bleeding (2-5 ml), short operation time, little tissue damage, few complications, quick recovery of the patient after the surgery, and low cost of the surgery. The superiority of this surgery makes doctors love it, patients suffer from it, medical staff involved in the treatment are convinced, and patients’ families are amazed. Over the past decade, more and more scholars have concluded that once a definite osteoporotic fracture is identified, instead of waiting for conservative treatment, PKP can be performed as early as possible, not only to quickly relieve the patient of severe pain in the low back, but also to significantly shorten bed rest, improve quality of life and prevent kyphotic deformity of the spine. The orthopedic spine and joint ward aims at the development of minimally invasive spine surgery, and percutaneous kyphoplasty has been actively and steadily carried out, and its exact efficacy has been widely recognized. In addition, we have developed a number of minimally invasive spine surgery techniques, many of which have become standard procedures in our department. These include minimally invasive unilateral TLIF, unilateral TLIF + subtle decompression of the contralateral spinal canal, percutaneous pedicle screw fixation, and expandable channel decompression fusion fixation. Currently, we are actively introducing intervertebral foraminoscopy, which is the core technology of minimally invasive spine surgery and will provide a new treatment option for the treatment of lumbar disc herniation, which has a high incidence.
