CT Diagnosis of Osseous Abnomalities of Lumbar Posterior Margin Concurrent Herniated Disk / 实用放射学杂志

ABSTRACT

Objective To improve the diagnosis of CT for osseous abnomalities of lumbar posterior margin concurrent herniated disk.Methods X-ray and CT scan materials of 56 cases with herniated intervertebral disks were retrospectively studied.Results The morbidity of osseous abnomalities of lumbar posterior margin includedlumbar posterior marginal intraosseons node、lumbar posterior marginal osteophytic formation,herniated disk calcification,post longitudinal ligmentum calcification,lumbar positerior marginal fracture.Conclusion This kind of osseous abaomality is a bony fragment that is seen to protrud into the spinal canal,compression of the dural sac and nerve root,concurrent displacement of intervertebral disk.Analysis in combination with X-ray and CT images of coronal or sagittal reconstruction is helpful increasing the accuracy rate of diagnosis.
