ABSTRACT
OBJECTIVE: To study the difference between two internal fixation methods Kaneda and Z-plate in the operation of anterior surgical approach and decompression after thoracolumbar fractures. METHODS: The bio-mechanical structure of the internal fixture, install when operating, complications and time of the operation were compared in the cases by Kaneda and Z-plate. RESULTS: Z-plate method had the following characteristics: reasonable of the bio-mechanical structure; stability after internal fixture being installed; capability of completely propping up the injured centrum and keeping the height of middle-column; simple operation when installing internal fixture and shorter time of operation (1.1 hours, P < 0.05); fewer complications. CONCLUSION: Z-plate is an ideal internal fixation method in the operation of anterior surgical approach after thoracolumbar fractures.
