Abstract:
BACKGROUND: Percutaneous kyphoplasty is of breakthrough significance in minimally invasive treatment of vertebral compression fractures, but it also has shortcomings, such as bone cement leakage, limited height recovery of the vertebral body, and increased risk of fracture of adjacent vertebral bodies. In recent years, a variety of spinal implants have been developed, and the application of these implants in the treatment of vertebral compression fractures in percutaneous kyphoplasty has achieved good clinical efficacy, and is beneficial to reduce the complications of traditional percutaneous kyphoplasty. OBJECTIVE: To describe the types and characteristics of various spinal implants and explore their clinical applications in percutaneous kyphoplasty. METHODS: CNKI, PubMed and Elsevier were retrieved for relevant literature. The key words were "percutaneous kyphoplasty, spinal implants, vertebral stents, vertebral compression fractures". Relevant articles published from January 2000 to June 2019 were reviewed, including review, basic research and clinical research. Preliminary screening was conducted by reading the article title and abstract, and the literatures with low relevance to the article topic were excluded. According to the inclusion and exclusion criteria, 62 articles were finally included for analysis. RESULTS AND CONCLUSION: (1) Spinal implants used in percutaneous kyphoplasty include VBS stent, Jack vertebra expander, SKY bone expander system, Osseofix system, SpineJack, KIVA system and memory alloy vertebral stent. (2) They are modified and developed on the basis of classic percutaneous kyphoplasty to achieve the same clinical efficacy while minimizing complications such as cement leakage, loss of vertebral height, and increased risk of adjacent vertebral body fracture.
