It's like a scene out of a "Terminator" flick ... doctors peeling back the skin on Anthony Smith's broken hand to show the metal rod holding the UFC star's bones together!!!
... and it's NASTY!!!
Yes, this is the ultimate "inside look" at Smith's injury -- taken during surgery Wednesday on his left hand.
As we previously reported, Smith fractured a bone in his hand while punching Alexander Gustaffson in the head over the weekend during their UFC Fight Night main event.
Despite suffering the injury in the 2nd round, Smith continued fighting and ultimately choked Gustaffson out for the victory in the 4th.
