Which positioning technique is used for a hand when performing a 'fan lateral' view?

The fan lateral view of the hand is designed to provide a comprehensive view of the phalanges. In this technique, the fingers are arranged in a fanned-out position. This technique enhances the visibility of the individual bones of the fingers and minimizes superimposition. By having the four fingers (2nd to 5th digits) arranged anterior to the first digit (thumb), it allows for a clearer distinction between the bone structures in the radiograph.

This configuration not only facilitates a better visualization of each finger but also assists in ensuring that any potential fractures or pathologies can be accurately assessed by offering less overlap. Therefore, the fanned arrangement of the digits in the specified order is crucial for optimal imaging results in a fan lateral view.
