Man that sucks. My BRS snapped at the joint under her breast area. That sucked. I glued it, but lost movement in that area due to the glue, Plus it has broken since...
Where did the Luka come off from? Hips are just a ball joint, but you will need to hold the other leg steady as the 'hip' piece is just like a coathanger (to put it simply) with balls on the end and will therefore move away from any force.
