A-C surgery would depend upon the grade of the separation. My concern was the way he landed on the elbow which could have driven the head of the humerus up into the glenoid and disrupted the integrity of the AC ligaments.
No siht. The angle he came down on the elbow, he could have also crammed the long thingy that fits up in that other thing, tearing a couple doo-dads loose from that what's it that makes the arm bone maintain its integrity, OR, the top bone could be cracked if not fractured, in which case, he'll be pretty sore.
So I sort of disagree in that this isn't very humerus. Not funny at all.
And polish up a bit on your spelling.
