Structural integrity after accident

My 2013 Acura MDX  was in in accident. While low
relativily low speed, it was a police car with the  
push assembly on the front end that hit at my front
wheel with the front corner of the cruiser. (His fault)
It then travel the full length of my car.  Cruiser has
only front corner damage so not a side swipe. The
impact has resulted in bearing, steering a
Rack, control arm, pillar between the doors to be
replaced.  When the pillar is replaced, what
happens to the part of the car that the pillar is
reattached to? Seems from where the pillar was
damaged so low next to the base, the framework it
ties into would be compromised?  Also since
assuming unibody frame with a hit in the front
corner from cruiser with the push assembly on the
front would have compromised the frame? Or can
these be straightened out without issues?
