Arm Rig breaks at wrist - Any Ideas how to fix it?

[Erik]

Dearest Animators,

I rigged an arm very simple shoulder-Elbow-Wirst bones attached to the Structure layers. And a Hand piece attached to the S|Structure.
I set up the character looking to the right side (of my screen).
When I lift the arm the rig breaks at the wrist. Any Ideas?

to the left - all is good , but to the right side it breaks

Try adjusting the hand rotation as you move the arm.
