Using the current Poser joint definition system, it is not possible to get joint deformations like in Maya as Stahlberg does. There would have to be a fundamental change in the way Poser handles joints in order to fix this problem (which is highly unlikely in the near future). There are a couple of workaround to help (but not solve) the problem....either export your posed mesh to another 3d app and fix the joint there, or build yourself some morphs to assist.
