Overview

The lateral lumbar spine radiograph profiles vertebral bodies intervertebral disc spaces and posterior elements to detect spondylolisthesis and compression fractures. The patient is positioned true lateral with knees flexed for comfort. This view is essential for evaluating sagittal balance and neural foramina indirectly.

Technique

Center the detector to include L1 to S1 and ensure true lateral alignment with minimal rotation. Use appropriate exposure and immobilize the patient to reduce motion. Flex knees to reduce lumbar lordosis when needed for better visualization.

Clinical Indications

Lateral lumbar spine is indicated for low back pain trauma and suspected compression fractures. It helps assess disc height spondylolisthesis and vertebral collapse. MRI is preferred for direct neural element and disc pathology evaluation.

Image Assessment

Measure disc heights and vertebral body alignment and assess for anterior or posterior displacement. Evaluate for compression fractures and osteophyte formation. Report findings relevant to surgical planning and conservative management.
