T5 or Fifth Thoracic Vertebra, Superior View

Description

Seen from above, the T5 vertebra presents the vertebral body anteriorly and the vertebral arch posteriorly, enclosing a relatively small, round vertebral foramen typical of the thoracic spine. Pedicles form the anterolateral walls of the canal and lead laterally into the transverse processes, while the laminae converge posteriorly toward the base of the spinous process. Superior articular processes sit posterolaterally with their facets oriented largely in the coronal plane, and costal facets at this level are positioned to receive the head and tubercle of the fifth rib. Clear joint surfaces. That superior perspective matters because T5 sits near the apex of thoracic kyphosis, where load transfer and facet orientation bias the region toward rotation rather than flexion and extension. The narrow canal makes thoracic cord compromise less forgiving in burst fractures or metastatic collapse, and the rib-bearing facets explain why thoracic fractures and dislocations often involve costovertebral and costotransverse joints as part of the injury pattern. Posterior elements at T5 also guide surgical anatomy for pedicle screw trajectories, where pedicle width and medial wall integrity are constant concerns. Use this plate in vertebral osteology teaching for anatomy and radiology courses, paired with axial CT to match the vertebral foramen, pedicles, and facet joints in the mid-thoracic spine. It also suits spine surgery texts discussing thoracic instrumentation, rib-related biomechanics, and the segmental anatomy relevant to thoracic epidural placement and laminectomy planning.
