Which structure in the dataset is associated with the lumbar angle?

• A. Structure A
• B. Structure B
• C. Structure F
• D. Structure E

Answer: (C)

The lumbar angle reflects the curvature of the lower spine, specifically the lumbar lordosis. That curvature is defined by the lumbar vertebrae, so the structure in the dataset that represents that region is the one labeled to correspond to the lumbar spine. In this item, that is Structure F. On radiographs, you evaluate lumbar lordosis by looking at the lumbar vertebrae region and the lines that trace the endplates within that region, which is why the structure representing the lumbar spine is the correct association. The other structures correspond to regions or features not defining the lumbar curvature, so they don’t match the concept of the lumbar angle.
