Abstract:

OBJECTIVE: To introduce application and advances of pedicle screw internal fixation in treating thoracolumbar fracture.
METHODS: A computer-based online search of PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) and CNKI database (www.cnki.net/index.htm) was performed for related articles with key words “vertebral pedicle screw, thoracolumbar fracture, internal fixation” in English and Chinese. Articles related to anatomic basis, biomechanical analysis, clinical application and advantages and disadvantages, published in authoritative journals recently in the same filed were included. A total of 31 articles were finally included.
RESULTS: Transpedicular internal fixators can effectively restore vertebral height and physiological curve to recover and fix the displaced bone block to original position to decompress the neural tube. Pedicle screw fixation can provide strong fixation, correct deformity, maintain spinal three-dimensional position, and provide good biomechanical stability. Recently, the combination of various techniques and development of minimal invasive technique increase posterior approaches for thoracolumbar fracture, which are all on the basis of pedicle screw fixation.
CONCLUSION: Pedicle screw fixation is an effective technique for thoracolumbar internal fixation and can be used for various thoracolumbar instabilities, in particular the thoracolumbar fractures.
