On May 30, 2014, the Department of Orthopedics of the First Affiliated Hospital of Tsinghua University successfully performed the first bone capsule filling vertebroplasty (Vesselplasty) in Beijing for a patient with osteoporotic lumbar compression fracture, successfully solving the problem of bone cement leakage that existed in conventional vertebroplasty (PVP), and now the patient’s postoperative low back pain is completely relieved, and he has already gone down to participate in The patient’s postoperative back pain has been completely relieved, and he has been discharged from the hospital. Patient Liang X (pseudonym) was hospitalized in the Department of Orthopedics of the First Affiliated Hospital of Tsinghua University 2 weeks ago for a lumbar 2 vertebral compression fracture caused by an accidental fall. Since the patient also had severe osteoporosis, vertebroplasty was the first choice for the treatment of the disease. However, after the family made inquiries at several large hospitals in the city, they learned that there was a certain risk of bone cement leakage from vertebroplasty, and although the chance of occurrence was very small, if leakage occurred, it could lead to lower limb paralysis or even life-threatening, so the patient was slow to make up his mind about surgery. After learning of this situation, Prof. Nie Yuanxin, director of the orthopedic department, took the initiative to chat with the patient and his family to dispel their concerns and introduce the patient to the new bone capsule-filled vertebroplasty (Vesselplasty), which was just certified by the State Food and Drug Administration in 2013. This technology was first designed by Taiwan’s A-SPINE in 2007, and was introduced to China in 2013 after experiments in many large hospitals abroad and after officially receiving certification from China’s CFDA. The Vessel-X capsular bag filler is made of interlocking polymer materials woven into a mesh bag structure, which can be expanded by direct infusion of viscous bone cement, and its dense polymer mesh structure can wrap most of the bone cement, and allow a small amount of bone cement to seep outside the mesh layer and couple with bone tissue; moreover, the shape of the bag is relatively fixed after expansion, which can better Moreover, the shape of the capsule is relatively fixed after expansion, which can better control the distribution of bone cement and eliminate the leakage of bone cement, thus greatly improving the safety of the surgery. After meticulous communication with the patient and consent from the family, the orthopedic department, under the leadership of Director Nie Yuanxin, made a strict surgical plan and contingency plan. At 10:00 a.m. on May 30, on the basis of adequate preoperative preparation, Director Nie Yuanxin began to operate on Liang X. The entire operation lasted 25 minutes. The whole operation lasted 25 minutes and was performed under local anesthesia, with the patient fully awake during the whole process. Under the monitoring of the C-arm, Director Nie accurately punctured the fractured lumbar 2 vertebral body through the vertebral arch and slowly injected 2.5ml of bone cement into the bone capsule, which slowly expanded and shaped, and coupled with the bone tissue by extending a small amount of burr-like bone cement. Intraoperative bleeding was only 1 ml, and all signs of the patient were normal. Patient Liang X felt more than 70% relief of back pain immediately after surgery, and could walk on the ground the next day with normal diet and self-care, without clinical complications. According to Nie Yuanxin, director of the Department of Orthopaedics of the First Affiliated Hospital of Tsinghua University, compared with the previous minimally invasive thoracolumbar fracture surgeries PKP (Posterior Kyphoplasty) and PVP (Vertebroplasty), the most important feature of the new Vesselplasty is that the bag for expansion is left inside the injured vertebral body and the bone cement is directly injected into the bag, thus eliminating This eliminates the possibility of bone cement leakage and even serious complications such as lower limb paralysis. In addition, the entire operation is performed under local anesthesia, and the surgical incision is only 5 mm, which can be performed without sutures, and the operation time is short. The successful implementation of this surgery, while providing a safer option for patients with osteoporotic thoracolumbar fractures, also promotes the whole concept of minimally invasive orthopedics one step further. It is reported that the Department of Orthopedics of the First Affiliated Hospital of Tsinghua University is the first department in Beijing to perform this surgery.
