Influential factors for pedicle screws breakage in 18 cases / 中国组织工程研究

ABSTRACT

0.05), showing that the breakage of pedicle screws had no obvious relation with material. Analysis of 4 observation indexes of two groups showed that the height of the affected intervertebral space was no correlated with the pedicle screws breakage, but the location of the pedicle screws, the degree of bony fusion and rail use were significantly related with pedicle screws breakage. CONCLUSION: Pedicle screw breakage in thoracolumbar fractures fixation are not obvious related to material; but it is correlated with pedicle screw location, degree of the bony fusion and rail use. Pedicle screw breakage is caused by interaction of multiple factors.
