There was a near equal distribution of onecolumn (12), two-column (9), and three-column (10) injuries, as well as a near equal involvement of anterior (20), middle (18), and posterior columns
In VitB12 deficiency, the dominant neurological pathology is myelopathy in the cervical and thoracic posterior columns
.  Magnetic resonance imaging of the spinal cord may show contrast enhancement involving the dorsal or lateral columns in VitB12 deficiency.
Sensory ganglionopathy appears to be mediated by direct mononuclear infiltration and destruction of the dorsal root ganglion and the posterior columns
of the spinal cord, promoted by the leaky basement membrane of the capillaries supplying these structures .
It showed that the femoral head-neck junction was entrapped through the hiatus created by the medially displaced quadrilateral surface between the anterior and posterior columns
Paraspinal-approach indirect reduction and fixation without fusion provides another treatment option for managing TLBF, in which there is an intact posterior longitudinal ligament and injury to the anterior and middle columns or to the anterior, middle and posterior columns
(Denis type B).
FA was first described in the 1860s by German physician Nicholaus Friedreich as a "degenerative atrophy of the posterior columns
of the spinal cord" (5).At a prevalence of 1:50 000 in European populations, it is the most frequent form of hereditary ataxia, although it is rare in sub-Saharan Africans and not yet seen in the Far East (6).
INTRODUCTION: The pedicles of thoracic vertebrae are tube like bony structures that connect the anterior and posterior columns
of pedicle .
Spongiform demyelization is produced in scattered plates that start at the level of the lateral and posterior columns
of the cervical and thoracic spinal cord, which can often affect the anterior columns with axonal degeneration and gliosis in advanced stages of the disease (8).
(10) Originating from the vertebral arteries, (10) the single anterior spinal artery supplies the anterior third of the spinal cord, including the central grey matter and anterolateral white matter, while the paired posterior spinal arteries supply the posterior third, including the posterior columns
Measurements used to predict difficult airway may, therefore, be classified into one of the three columns described in this model: the anterior, middle and the posterior columns
4) and, inside it, the posterior columns
of the fornix, parallel to the posterior part of the alveus.
