What is the recommended positioning for a patient's finger for a lateral projection of the fourth digit?

• A. Rest the hand on the radial surface with the fourth finger extended
• B. Rest the hand on the ulnar surface with the fourth finger extended
• C. Rest the hand flat with all fingers straight
• D. Position the finger in an upward angle

Answer: (B)

For a lateral projection of the fourth digit, the recommended positioning involves resting the hand on the ulnar surface while keeping the fourth finger extended. This positioning enables the fourth digit to be accurately depicted in a lateral view, which is crucial for assessing the joints and possible fractures or abnormalities in the finger. Placing the hand on the ulnar surface allows for better alignment and separation of the fourth digit from the other fingers, which minimizes overlying shadows that could obscure diagnostic details. Additionally, extending the finger ensures that it remains in a true lateral position, facilitating clear visualization of anatomical structures. This method of positioning is standard in radiography as it provides the necessary contrast and orientation for optimal imaging, making it easier for the radiologist or clinician to evaluate the finger accurately.
