[Imageology study of correlation loss and its related factors after short-segment pedicle screw reduction and fixation for lumbar fractures].

To analyze the correction loss after posterior segmental fixation for lumbar spine fractures and explore the related image factors. Posterior short-segment fixation was received in 48 patients with L 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 ( 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.
