摘要
Abstract
BACKGROUND: Posterior lumbar interbody fusion cage is one of the main means for the treatment of disc disease. The application of posterior lumbar interbody fusion can cause cage subsidence and other complications due to improper design, besides improper indication selection and improper surgical operation. OBJECTIVE: To optimize the cage design by reviewing the development of cage and concluding the other scholars’ biomechanical research on the application of posterior lumbar interbody fusion cage. METHODS: A computer-based searched was performed in CNKI ful -text database for the articles on optimize design of posterior lumbar interbody fusion cage from January 1990 to February 2012. The key words were“posterior lumbar interbody fusion cage, sinkage, design, bone graft fusion, biomechanical”. The literatures of irrelevant purpose and repetitive content were eliminated, and then 18 literatures were included and checked the Modern Spine Surgery and Spinal Internal Fixation Operation and other related books for further analysis. RESULTS AND CONCLUSION: After optimization, the cage implanted in the interbody could acquire sufficient strength, which can support the end-plate and prevent cage from the early subsiding within the vertebral body. At the same time, the optimization can greatly increase the fusion area, further reduce the stress shielding, improve the fusion rate, accelerate the fusion process, reduce the subsidence, displacement and other complications, and al this wil get a satisfactory clinical effect.关键词
