Abstract:
Objective To investigate the relationship between vertical laminar fracture(VLF)in thoracolumbar burst fractures and both neurological injury and dural tear.Methods A retrospective analysis was conducted on the clinical data and multi spiral computed tomography(MSCT)coronal images of 255 patients of thoracolumbar burst fractures.The patients were divided into three groups based on the presence of VLF[Ⅰ group(complete VLF group),Ⅱ group(partial VLF group),and Ⅲ group(normal lamina group)].Statistical analysis was performed using analysis of variance and Fisher's exact test to compare radiological parameters,inci-dence of dural tear,and neurological injury among the groups.Results The Ⅰ group showed significant differences in spinal canal sagittal diameter,pedicle distance,and spinal canal area compared with the other two groups(P<0.05).However,there was no sig-nificant difference in vertebral body compression rate between the Ⅰ group and the Ⅱ group(P>0.05).The Ⅰ group had the high-est incidence of severe neurological injury[American Spinal Injury Association(ASIA)impairment scale grades A and B]and dural tear(P<0.05).Conclusion The severity of VLF is closely related to dural tear and neurological injury.MSCT coronal images can clearly display the extent of VLF,providing an important basis for clinical evaluation and treatment plan.
