Abstract:

BACKGROUND: For thoracolumbar fractures, there are a lot of fixed ways, however, at present intermediate screws in short segment pedicular fixation is minimal damage, cost less, and fixed tightly.
OBJECTIVE: To systemic illustrate the technology of intermediate screw and clinical application effect.
METHODS: A computer-based online search was performed on PuMed database and CNKI database with key words of “Intermediate screws, pedicular screw fixation, thoracolumbar fracture” in English and Chinese from January 1983 to June 2011. Repeated literatures were eliminated.
RESULTS AND CONCLUSION: A total of 48 articles were included to review. Biological mechanics experimental and clinical application result indicates that intermediate screws in short segment pedicular fixation can instantly reset vertebral fracture, restore vertebral body height, and compared with the traditional short segments of the posterior fixation, intermediate screws in short segment pedicular fixation can effectively reduce the incidence of complications of internal fixation loose or screw breakage, vertebral height lost again.
