do you have an xray that shows this exactly?
from what i remember of anatomy i cant picture what you are describing and that pic shows nothing out of the ordinary to me.
of course when i read what you said, i imagined that the humerus was dislocated and sitting in an anterior position. after reading it again and again all i could imagine is that the humerus is pronated in to such a degree that what you described is happening. and for that i would need to see where the elbow lies which i cannot see in that pic.
are we on the same page here or am i just not seeing the forest for the trees?
