Answer
Bob-

Sorry about the misfortune. I am afraid that some damage may have been done to the hinge pillar. This may require the assistance of a body shop or some sort of hydraulic action to pull the hinge pillar back into shape, new hinges or even some other more involved repair. I can't advise you to drive the vehicle with the door open even partially but many times I have been presented with a vehicle with a similar condition at the shop. Have it looked at and see what they think. Good Luck- Mark
