Instead of making the IK from the shoulder to the wrist, have it go from the shoulder to the extra joint. Then, go into Hypergraph, find the effector for that IK and use insert mode to snap it to the wrist. Now the arm moves as if you had made the IK from the shoulder to wrist, but doesn't rotate the extra joint you've added.

Also, if you have more joints in your forearm or a more complex setup. You can create a simpler arm, with just a shoulder, elbow and wrist and use it to drive the more complex one with orient constrains.

Good Luck :thumbsup:
