Overview
The lateral thoracic spine radiograph profiles vertebral body heights and intervertebral disc spaces to detect compression fractures and kyphosis. The patient is positioned true lateral with arms elevated to clear the thoracic region. This view is sensitive for anterior wedge compression and alignment abnormalities.
Technique
Center the detector to include the thoracic spine and ensure true lateral alignment with minimal rotation. Use appropriate exposure and immobilize the patient to reduce motion. Consider full spine imaging for scoliosis assessment.
Clinical Indications
Lateral thoracic spine is indicated for trauma back pain and suspected compression fractures. It helps evaluate sagittal balance and vertebral body collapse. MRI is used for spinal cord and soft tissue assessment when indicated.
Image Assessment
Measure vertebral body heights and assess for anterior wedge deformity and kyphotic angulation. Evaluate disc spaces and posterior element alignment. Report findings and recommend advanced imaging for neurologic compromise.
