Imageology study of correlation loss and its related factors after short-segment pedicle screw reduction and fixation for lumbar fractures / 中国骨伤

OBJECTIVE@#To analyze the correction loss after posterior segmental fixation for lumbar spine fractures and explore the related image factors.@*METHODS@#Posterior short-segment fixation was received in 48 patients with L@*RESULTS@#The average follow-up was 12 to 18 (16.13±5.39) months. LKA, AVH and VWA at 1 week postoperative and those at the final follow up, were significantly improved compared with those preoperative (@*CONCLUSION@#The angle of adjacent intervertebral discs and anterior height of injured vertebrae were lost statistically after posterior short-segment pedicle screw treatment for lumbar fractures, and multivariate analysis showed that all of them were correlated with load-sharing score.
