My character was assaulted and, among other injuries, her right forearm was fractured severely. It was surgically repaired using pins.
My question is: Is it possible for her to develop osteomyelitis after a blunt-force trauma (that does not result in a fracture) two years after the original injury? If not, is there another scenario that could cause osteomyelitis after the fact like that? And what would be the immediate treatment plan following the second injury and osteomyelitis? Also, if left untreated for a period of time, could osteomyelitis become life-threatening?
The first part of your question does not seem plausible to me. First, you imply that there isn’t a fracture associated with the second injury to this arm and the length of time doesn’t quite work. The arm should be fully healed two years post surgery to repair the fracture.
If this character were to develop osteomyelitis near the site where she received a blow by a blunt object, but that arm had been previously fractured two years prior, I don’t see the medical staff thinking these two things are related. They are just too far apart.
I don’t know of another scenario that could cause this to happen two years out– that the blunt force blow (that doesn’t break the skin or cause fracture) somehow ignites an osteomyelitis at a previous surgical site. If it did, I think it would be considered happenstance.
Ostemyelitis generally happens when bacteria gets to the bone through an open wound (open fractures are a great way to write this complication) or the infection to the bone is seeded from another area in or on the body (a septic joint for instance). The infection will generally develop within two weeks. Even in the article linked in this paragraph, chronic osteomyelitis usually develops within two months. Nothing even close to two years.
The course of treatment for osteomyelitis would depend on what bacteria (or fungus) is causing the infection. Surgery could also be indicated.
Yes, any infection can become life threatening particularly if the bacteria or fungus gets into the bloodstream.
Hope this helps and good luck with this story!
