An acute infection is going to happen soon after the injury or the surgery. Let’s say you break your leg, you have a rod put in your leg, and within two weeks the incision starts to drain a little bit. That’s usually what we would call an acute infection. It’s a lot different than an infection that doesn’t really manifest itself for 9, 10 months or even a couple of years. Again, it’s a question of timing. An acute infection is often easier to get rid of because you catch it early on, it hasn’t had a chance to establish itself. The soft tissues may be part of the issue, but the bone really hasn’t been thoroughly colonized where you must remove infected, dead bone. Whereas an infected non-union, the infection has been there longstanding, it’s into the bone usually, and you have to then get rid of that bone in order to cure the infection. It’s a question of chronicity, how long has it been going on prior to you noticing it or it becomes clinically manifest.
