T11 Vertebra

Description

Seen in lateral profile, the lower thoracic vertebral column transitions toward the lumbar region, with T11 highlighted in blue against adjacent vertebrae and the intervening intervertebral discs. The T11 vertebral body sits anterior to the vertebral foramen, while the laminae and spinous process project posteriorly to complete the vertebral arch. Superiorly and inferiorly, the endplates of T11 articulate with the T10 to T11 and T11 to T12 discs, and the posterior elements align in a gentle thoracolumbar curvature. Facet (zygapophysial) joints stack posterolaterally, guiding motion between levels. A key landmark. T11 matters because it sits near the thoracolumbar junction, where rib-bearing thoracic morphology gives way to lumbar load-bearing mechanics and where stress concentrates during flexion and axial loading. Clinically, wedge compression fractures often occur around T11 to L1, and a lateral view makes anterior vertebral body height loss and kyphotic angulation easier to appreciate than an en face projection. This level also frames teaching about vertebral foramen caliber changes along the column and how canal dimensions relate to cord and cauda equina anatomy as you move caudally. Use this illustration in gross anatomy labs and radiographic anatomy modules when correlating vertebral body shape, disc spacing, and sagittal alignment on lateral spine radiographs or CT sagittal reconstructions. It also fits well in orthopaedics and emergency medicine teaching materials on thoracolumbar trauma classification and vertebral compression fracture patterns, where a singled-out T11 helps anchor level identification.
