On the left side, You probably don't have a row of polygons belonging to HIP between abdomen and thighs. If you skip a group in a hierarchy, the polygons don't stay connected to one another when bending.  I learned that the hard way too!

On the right, at his groing, probably the same thing, perhaps a few polygons are not in the right group.  Make sure you have 'bend' turned on in properties. That's happened before too, I'd be looking for advanced problems, and miss something really simple.
