Broken figure hip

Not a great way to fix that. If you want to try to avoid taking it completely apart, which would be better, you can try drilling a small hole on the peg portion and a small one on the other part it careful not to drill through. Insert a piece of paper clip or similar into the hole and glue. Plastic epoxy would work the best but you'd need to be very careful and wrap a rubber band around the joint until the glue dries. You may want to try super glue first and see if it holds.
