At the risk of intruding into your personal life Linda, could you share how he obtained his fracture?
I had an orbital blowout fracture, I did have to have surgery but not to repair that injury, and it was a result of being attacked by a large ex boyfriend. And I know the exact hit that did it; it was the first hit I received in the attack, and his fist was swung like a hammer, not knuckle first.
I found this article describing what exactly a blowout fracture is, among the other type of orbital fractures, and what the symptoms often are:
