What projection is typically performed in conjunction with the lateral projection to complete a radiographic examination of the calcaneus?

The AP projection is commonly performed in conjunction with the lateral projection to complete a radiographic examination of the calcaneus. This is because the lateral view provides detailed information about the anatomy of the calcaneus from the side, while the AP view captures the bone from the front, allowing for a comprehensive assessment of the bone structure and any potential abnormalities. This combination aids in visualizing the calcaneus in both dimensions, which is crucial for accurate diagnosis and treatment planning.

In the context of the other options, the PA oblique, oblique lateral, and medial oblique projections are not standard views used to complement the lateral view for calcaneal imaging. They focus on different perspectives or adjacent structures, which may not provide the necessary information about the calcaneus specifically when paired with a lateral view. Hence, the AP projection is the correct choice for completing the examination effectively.
