The site is secure. Although this can be theorized from our results, at present, these indices can only serve as reference for identifying subjects with narrowed spinal canals without further longitudinal follow-up of these asymptomatic individuals. Reduction with traction may take 5 to 6 days. All subjects underwent MRI for diagnosing DSS and radiographs for measuring parameters used for creating the indices. Your physician will notify you of this prior to the Patient sample: Sagittal MRI best identifies associated neural lesions (eg, medulla, pons, cerebellar, spinal cord, and vascular abnormalities; syringomyelia) and soft-tissue lesions. As such, the aim of this study is to develop practical radiographic indices for diagnosing DSS. One study suggests that the anteroposterior diameter of the thecal sac at the S1 level should be greater than that of the thecal sac at the L4 level in order to describe dural ectasia 4.
