What should be visible in a properly performed lateral calcaneus radiograph?

In a properly performed lateral calcaneus radiograph, the goal is to provide a clear view of the calcaneus, or heel bone, along with the surrounding tarsal bones. This comprehensive perspective is essential for assessing the integrity of these structures, diagnosing fractures, and understanding any potential deformities. The entire calcaneus should be visible, showcasing its shape and relation to adjacent bones, such as the talus and cuboid, which are crucial for evaluating the overall anatomy and function of the foot.

It is important for the radiograph to capture not only the calcaneus but also elements of the surrounding anatomy to ensure a thorough examination. This visibility aids in identifying any abnormalities that might not be apparent if the focus were restricted solely to the calcaneus itself. Therefore, having the whole calcaneus along with other tarsals in view leads to improved diagnostic accuracy and understanding of foot mechanics.
