Multiple-level Noncontiguous Spinal Fractures In Adolescent Using Pedicle Screw Fixation

Objective: Analysis study the clinical outcome of pdicle screw fixationfor adolescent non-continuous multi-segmental spinal fractures. Methods: Theretrospective study14cases of adolescent non-continuous multi-segmentalspinal fractures with pdicle screw fixation treatment from January2005toDecember2013. For different patients were performed long segmentcontinuous fixed, short segment respectively fixed. By comparing before andafter surgery, follow-up X-ray, CT, MRI, anterior vertebral height (AVH), theangle of the injured vertebral, sagittal index (SI), thoracic and lumbar lordosis,and intraoperative after the trunk balance and other indicators were observedand measurements. Come to change the relationship between the change ofvarious indicators and the loss of correction postoperative by statisticalmethods. Results: Statistically significant improvements were found in thepercentage of anterior vertebral height (AVH%), the angle of the injuredvertebral and sagittal index (SI) of the pre-and post-operative assessments(P<0.05). have not statistical significance comparison to the last follow-up. Buthave not statistical significance were found percentage of posterior vertebralheight (PVH%) of the pre-and post-operative assessments (P>0.05),Postoperative thoracolumbar lordosis straight. Conclusions: Long segmentpedicle screw fixation and short-segment continuous are effective way of treating MNSF; Internal fixation surgery resulted in young patients spinalcurvature straight, And postoperative activity is limited. The neurologicalfunction of the patients can be improved to some extent after nervedecompression surgery.
