Methods: CT imaging files of 152 consecutive traumatic patients with thoracolumbar fractures were retrospectively reviewed. MSCT scannings were performed with a collimation of 3-5 mm and a pitch of (5.5). The postprocessing included sagittal and coronal multiplannar reconstruction, and 3-D reconstruction.Results: There were 88 cases of compression fracture, 54 cases of burst fracture and 10 cases of fracture-dislocation. Transverse images of MSCT could visualize all fractures directly and determine whether spinal canal was intact. Postprocessing image was helpful in depicting the displacement of fragment and orientation of dislocation.Conclusions: MSCT plays an important role in diagnosis and management of acute thoracolumbar spinal fracture and fracture-dislocation.展开更多

Patients who had an improvement in LBP scores evaluated by Japanese Orthopaedic Association （JOA） scoring system during the fol- low-up periods were classified as the recovery group, and others were classified as the non-recovery group. Patients＇ clinical data and radiographic parameters like lordosis angle, range of motion and intervertebral rotational angle were analyzed using binary logistic regression analysis to detect factors significantly related with the occurrence of residual LBP. Results： The average preoperative JOA score of 14.8± 5.05 improved to 21.59±5.51 at the final follow-up. Binary logistic regression analysis revealed that significant predictors of residual LBP were preoperative lumbar lordosis angle and range of motion. Conclusions： Our results suggest that patients with flat back and limited lumbar mobility before surgery tend to have poor results in terms of LBP. Therefore, these sagittal radiographic parameters should be taken into account when choosing laminectomy as the surgical option for LCS.展开更多
