Abstract: BACKGROUND: Percutaneous vertebroplasty is an important treatment for osteoporotic vertebral compression fractures. With the development of clinical practice, its limitations gradually revealed. Many researchers have studied and improved it. OBJECTIVE: To summarize the latest research progress on the navigation and surgical approach, fracture reduction system, prevention of cement leakage, and bone cement materials. METHODS: The computer was used to search relevant articles from PubMed, Embase, CNKI, Wanfang, and VIP databases from January 2000 to April 2020. The Chinese and English terms were “osteoporotic vertebral compression fracture, percutaneous vertebral augmentation, percutaneous vertebroplasty, percutaneous kyphoplasty”. After consulting the relevant articles, 61 articles were included to analyze the results. RESULTS AND CONCLUSION: (1) O-arm navigation and 3D printing technology are very helpful for patients with upper thoracic vertebral compression fracture, severe vertebral compression fracture, and compression fracture with scoliosis. (2) Most opinions think that unilateral approach is more advantageous than bilateral approach, but further research is still necessary. (3) There are many fracture reduction systems and technologies of preventing cement leakage. Different structural characteristics make them have their own advantages, which one should be chosen to treat patients depends on different conditions. (4) Calcium phosphate cement has great potential and may gradually replace traditional bone cement materials in the future.
