How...would they get their wings beneath their body? The joints attach above their shoulders...
the dragon has elbows and very flexible wrist joints, I'm also assuming the wing socket allows it to rotate - if the dragon was in a upright bipedal posture (like when flying maybe) it would just be a normal 'extra' set of arms with claws rotated so they orientate inwards.
