Superior Vertebral Notch Of The Thoracic Vertebra, Superior View

Description

Thoracic vertebra anatomy is centered here on the superior vertebral notch (incisura vertebralis superior) along the superior border of the pedicle. From a superior viewpoint, the vertebral body sits anteriorly, while the pedicles project posteriorly toward the laminae and spinous process, and the curved notch is visible as a concavity on the superomedial margin of each pedicle. Posterior to the body, the vertebral foramen opens centrally, bounded laterally by the pedicles and posteriorly by the laminae; the transverse processes extend laterally, with the superior articular processes positioned posterolaterally. The superior vertebral notch matters because it forms the superior half of the intervertebral foramen when paired with the inferior vertebral notch of the vertebra above, creating the osseous corridor for thoracic spinal nerves, radicular arteries, and accompanying veins as they pass laterally from the vertebral canal. Foraminal stenosis from osteophytes or facet arthrosis can narrow this space and produce thoracic radiculopathy, and the pedicle margin adjacent to the notch is a key landmark when planning pedicle screw trajectories where cortical breach risks neural or vascular injury. Sharp light falloff across the concavity helps separate the notch from the pedicle’s cylindrical profile, which is exactly where learners tend to lose the boundary between pedicle, foramen, and canal. Small structure, big consequences. Use this illustration in vertebral column modules for gross anatomy, in orthopedic or neurosurgical teaching on thoracic pedicle fixation, and in radiology education when correlating osseous foraminal boundaries on CT bone windows. It also supports publisher figures on spinal nerve exit anatomy and foraminal stenosis mechanisms. Anatomical accuracy verified by SciePro's Medical Advisory Board.
