A Superior View Of The Inferior Costal Facet Of The Thoracic Vertebra

Description

Rotating in a superior perspective, the thoracic vertebral body fills the frame with the inferior costal facet (fovea costalis inferior) cut into its posterolateral lower margin. The sequence clarifies how this demifacet sits inferior to the superior costal facet and anterior to the vertebral foramen, with the pedicles rising posteriorly toward the vertebral arch. As the camera tracks subtly across the rim of the body, the smooth articular surface of the costal facet contrasts with the surrounding cortical bone and adjacent intervertebral disc margin. Clinically, this small indentation is the bony half of the costovertebral joint that meets the head of a rib, so its position explains both normal rib kinematics and pain generators at the thoracic spine. Close-ups of the demifacet help anchor level-specific anatomy, including why a typical rib head spans two vertebral bodies and why degenerative change or inflammatory arthropathy at the costovertebral articulation can refer pain along the rib and mimic cardiopulmonary symptoms. Motion makes the relationships easier to teach: a static plate rarely communicates how the facet’s location on the vertebral body predicts where a rib head will sit relative to the spinal canal and the intervertebral disc. Use this animation in thoracic osteology and regional anatomy teaching, rib and spine biomechanics lectures, and radiology correlation for CT bone windows where costal facets can be subtle but diagnostic of thoracic level. It also suits surgical education when discussing posterior approaches to the thoracic spine and the need to respect costovertebral joints during rib head resection or deformity work-up.
