Abstract:

BACKGROUND: The posterior transpedicular instrumentation of bone graft and vertebral pedicle screw in fractured vertebra has been widely used in the treatment for thoracolumbar fractures. Prior to its feasibility, effectiveness, safety and other aspects of biomechanics and clinical research, but there are still more controversial.
OBJECTIVE: To summarize the effectiveness and security of thoracolumbar fractures treated with posterior transpedicular instrumentation of bone graft and vertebral pedicle screw in fractured vertebra.
METHODS: VIP database and PubMed database (1989-01/2011-09) were used to search the related articles about the treatment of thoracolumbar fractures with posterior transpedicular instrumentation of bone graft and vertebral pedicle screw in fractured vertebra. The key words of “thoracolumbar fractures, injured vertebral, fixation, bone graft” in Chinese and English were put in the title and abstract to search the relate articles. Finally, a total of 33 articles were included to review.
RESULTS AND CONCLUSION: The posterior transpedicular instrumentation of bone graft and vertebral pedicle screw in fractured vertebra is a more solid fixation, while helping to fracture reduction and kyphosis correction, and benifit to restore and maintain the vertebral height, reduce the correction rate of loss. However, the surgery reports at present are mainly the retrospective analysis, and there lacks the long-term follow-up, a series of forward-looking analysis and research, as well as the evidence-based medicine, and there is considerable controversy on the indications of nail set on the injured vertebral, security and technical specifications, which need further study and improvement.
