Can you get a rib fracture as a result of anesthesia?

Can you get a rib fracture as a result of anesthesia? Had back surgery on 12/8- complained x3 post op visits to surgeon about left side rib pain. He said the rib pain had nothing to do with the back surgery. .Still having pain, saw GP on 2/1- Chest x-ray shows healing 7th left side rib fracture. Pre OP chest x ray is normal I have not bee sick. Can this fx have been a result of the anesthesia?
