Superior Articular Facet Of The Thoracic Vertebrae, Posterior View

Description

Superior articular facets (facies articulares superiores) of a thoracic vertebra are presented from a posterior perspective, highlighting the smooth cartilage-bearing surface on the superior articular process (processus articularis superior). Each facet faces posteriorly with a slight lateral orientation, positioned just lateral to the base of the spinous process and posterior to the pedicle-lamina junction. Surrounding bony landmarks logically in frame include the laminae converging toward the midline spinous process, with the superior articular processes rising superiorly and slightly posterolaterally from the vertebral arch. Orientation is the point. Facet orientation in the thoracic spine underpins segmental mechanics and pain patterns, since the zygapophysial joints (articulationes zygapophysiales) bias rotation while limiting flexion and extension compared with the lumbar region; seeing the posterior-facing articular surface helps explain why thoracic facet loading increases with extension and ipsilateral rotation. Degenerative facet arthropathy, synovial cyst formation, and post-traumatic capsular irritation are common generators of axial thoracic pain, and the clinician often correlates symptoms with palpation along the paraspinal gutter just lateral to the spinous processes. The fixed posterior viewpoint also supports procedural planning by anchoring the facet to palpable posterior elements, a practical reference when discussing fluoroscopic obliquity for medial branch blocks or radiofrequency ablation at thoracic levels. Use this illustration in gross anatomy and musculoskeletal courses when contrasting cervical, thoracic, and lumbar zygapophyseal joint planes, or in spine surgery and pain medicine materials explaining thoracic facet-mediated pain and target selection for diagnostic blocks. It also suits journal figures and patient-facing educational handouts that need a posterior bony landmark map without distracting soft tissues.
