In the case of a broken arm, what should be done before applying a splint?

Before applying a splint to a broken arm, it is essential to assess circulation and sensation. This step is vital for several reasons. First, evaluating blood flow ensures that the nerves and blood vessels are intact and functioning properly. If there is significant swelling or displacement of the fracture, assessing circulation aids in determining the need for immediate medical attention, as compromised circulation can lead to further complications, including tissue damage.

Furthermore, checking for sensation helps to identify any potential nerve injuries that may have occurred alongside the fracture. If the patient reports numbness, tingling, or an inability to move their fingers, it underscores the importance of prompt medical evaluation. Ensuring that circulation and sensation are intact before splinting can guide how to splint the injury effectively and prevent additional harm.

In this context, moving the arm to a comfortable position might seem beneficial, but it could exacerbate the injury if not done carefully. Shouting for help continuously may not be practical or helpful in managing the situation effectively. Keeping the arm hanging loosely may not provide the necessary stability and immobilization required for a fracture, potentially allowing for further injury.
