Which of the following describes the correct patient positioning for lateral calcaneus radiographs?

For lateral calcaneus radiographs, the ideal positioning is seated or lying down. In this position, the patient is more stable and can easily maintain the required posture to obtain a clear image of the calcaneus without unnecessary movement. This stability is crucial for achieving an accurate radiograph.

Additional context for the other positioning options: while standing upright can capture certain aspects of weight-bearing views, it is not conducive to obtaining a true lateral view of the calcaneus. Supine positioning may not effectively isolate the calcaneus for lateral imaging and can cause discomfort. Prone positioning with feet hanging off the table may lead to difficulties in achieving the correct angle and alignment necessary for optimal visualization of the lateral aspect of the calcaneus. Thus, the seated or lying position is the most appropriate for this procedure, ensuring clarity and accuracy in the radiographic representation.
