Question of the Day:

We notice that our snowboarder with the anterior shoulder dislocation has trouble abducting his arm. He cannot abduct it beyond the first 20 degrees. What nerve has been damaged, where is it damaged, and what muscles are affected? How could this be confirmed by testing cutaneous sensation?
