Interrater and intrarater reliability of lumbar spine magnetic resonance assessment of military aircraft pilot candidates.

Background: The development of diagnostic imaging facilitates evaluation of spinal anatomy, but there is no full correspondence between morphologic and pathologic changes observed in radiographic studies and clinical findings. The aim of the study was to: 1. Evaluate the degree of signal intensity and degenerative changes of intervertebral discs in the lumbar spine on MRI.

Classical and modern classifications of luxations and fractures of thoracolumbar spine. Biomechanical and clinical aspects. Review of literature.

The authors present the advantages and disadvantages of the Denis and AO classifications based on a review of classical and recent literature concerning the evolution of classification of thoracolumbar spine conditions. The newest classification of fractures proposed by Vaccaro (TLICS - Thoracolumbar Injury Classification Severity Score) is discussed in detail. Special attention is given to instability in these fractures.

Digital computed tomography affords new measurement possibilities in lumbar stenosis.

Introduction: The problem of lumbar stenosis has been analysed at length in the literature as the number of patients with low back pain of this aetiology continues to increase. The aim of this study was:1. to carry out a prospective study assessing the dimensions of spinal canal on the basis of CT data and to compare patient data with a control group.
