A swollen, painful deformity to the lateral bone of the left forearm suggests injury to which bone?

Explanation:
When assessing a forearm injury, focus on which bones are in that region. The forearm has two bones: the radius and the ulna. In the anatomical position, the radius is on the lateral side (the thumb side) and the ulna is on the medial side (the pinky side). A swollen, painful deformity on the lateral aspect of the forearm points to the radius being injured. The humerus is the upper arm bone, and the clavicle runs from the sternum to the shoulder, so they are not involved in a forearm deformity.
