Abstract:

BACKGROUND: With the development of diagnostic radiology, biomechanics, a variety of new fixation devices and methods emerged in recent years, the growing number of thoracolumbar fractures can be treated through surgery.
OBJECTIVE: To study the pedicle screw implantation for thoracolumbar fractures.
METHODS: A computer online retrieval was performed to search papers regarding the pedicle screw implantation for thoracolumbar fractures, using key words of “thoracolumbar fracture, internal fixation, pedicle, screw, pedicle screws” in both Chinese and English. We summarized thoracolumbar injury severity score, clinical application of pedicle screw, and the characteristics of pedicle screw internal fixation, and analyzed pedicle screw internal fixation for thoracolumbar fractures.
RESULTS AND CONCLUSION: Pedicle screw fixation is an effective thoracolumbar fixation technique, which can be used for various reasons-induced thoracic and lumbar instability, in particular the treatment for thoracolumbar fractures. Pedicle screw fixation provides rigid internal fixation, which can correct deformity and maintain the spine three-dimensional position, and provides better biomechanical stability. Pedicle screw fixation system can effectively rebuild vertebral height, restore physiological curvature, relieve spinal cord nerve oppression, restore the diameter of the damaged spinal canal, and reconstruct spinal stability, correct kyphosis. Pedicle screw fixation with fewer traumas, satisfactory reduction, fixed and strong, easy to operate and other advantages has been widely used in clinic.
