Abstract:

OBJECTIVE: To evaluate effect and adverse effect of pedicle screw internal fixation for thoracolumbar fracture.
METHODS: A computer-based online search was performed with key words “thoracolumbar, fracture, injured vertebra, pedicle screws, internal fixation” in Chinese and English for articles published between January 1993 and October 2009. Articles related to injured vertebra pedicle screws internal fixation for thoracolumbar fracture were included. Repetitive and Meta analysis was excluded. A total of 22 studies were included, which discussed clinical outcomes and adverse effects of injured vertebra pedicle screws internal fixation for thoracolumbar fracture.
RESULTS: Pedicle screws internal fixation through injured vertebra can obtain favorable reduction, reconstruct vertebral height, enhance spinal anti-compression and stability, reduce loosening or breakage, and decrease complications. Biomechanical test shows that pedicle screws internal fixation through injured vertebra can enhance spinal stability. Clinical application shows that pedicle screws internal fixation through injured vertebra is operable, and appropriate, reliable fixator and tools, rigorous operation can reduce adverse effects.
CONCLUSION: Pedicle screws internal fixation through injured vertebra is a reliable and effective therapy for thoracolumbar fracture, with few adverse effects.
