Pathoanatomical Changes in the Thoracolumbar Junctional Region of the Spine

Pages 367-368 | Received 29 Aug 1989, Published online: 08 Jul 2009
 

Abstract

The thoracolumbar junctional region (T10-L1) of the spine is a transitional zone, where more than half of the thoracic and lumbar fractures occur. In this presentation the origin of the pathoanatomical changes in the thoracolumbar junctional region of the spine is discussed in view of the previous studies. These studies refer to a torsional force contributing to the formation of the degenerative changes, especially in the facet joints. Degenerative changes anteriorly and posteriorly do not concur in the thoracolumbar junctional region. Only a weak concurrence is found between disc degeneration and spondylosis, which refer to differences in their pathomechanisms. A strong concurrence between the degenerative changes at different levels, especially anteriorly, reflects factors causing overall degeneration in the thoracolumbar junctional region.
