A Posterior View Of The Superior Articular Process Of The Thoracic Vertebra

Description

Arising from the junction of the pedicle and lamina, the thoracic superior articular process projects superiorly from the vertebral arch and is presented from a posterior viewpoint. The animation tracks the upright, flattened plate of the process as it leads into the superior articular facet, oriented to meet the inferior articular facet of the vertebra above and form a zygapophysial (facet) joint. As the camera settles, adjacent landmarks come into register, including the laminae flanking the spinous process medially and the transverse processes extending laterally. Facet orientation matters in the thoracic spine. Thoracic superior articular facets are generally arranged closer to the coronal plane than in the lumbar region, a geometry that favors axial rotation while limiting flexion and extension, and that distribution of motion helps explain common pain generators in the mid back. Seeing the process and facet surface sequentially, with subtle changes in angle and depth, clarifies where capsular synovitis, osteoarthritic hypertrophy, or small osteophytes can narrow the adjacent intervertebral foramen and contribute to radicular symptoms, and it mirrors the bony targets used during fluoroscopic or CT guided medial branch blocks. Use this clip in vertebral osteology labs, thoracic spine biomechanics lectures, or as an anatomical callout in radiology and pain medicine materials discussing facet joints, medial branch innervation, and thoracic facet interventions. It also fits surgical education on posterior approaches where precise identification of the superior articular process guides orientation before addressing the lamina, pars region, or adjacent joint capsule.
