The measurement of the coronal dimensions of the spinal canal is typically done by assessing the interpediculate distance. This distance refers to the space between the pedicles of adjacent vertebrae in the lumbar spine, representing the width of the spinal canal at that level. It is a crucial measurement as it helps to evaluate the potential for canal stenosis and can be essential for surgical planning, particularly in procedures involving decompression or fusion.

Focusing on this dimension provides valuable insight into the anatomical space available for the spinal cord and nerve roots. Other measurements, such as canal width, vertebral height, and angle of the spine, do not directly assess the coronal dimensions of the spinal canal. Each of these alternatives serves different purposes in spinal assessments, but they do not specifically measure interpedicular distances, which are key to understanding spinal canal width in relation to neurological conditions.
