It depends on the fracture. Some will go on to fusion no matter who fixes them.
This morning one of my co-residents on Ortho trauma now got a call to the ER for an open fracture.
The guy was rock climbing on a rock wall and forgot to hook his carbeaner to the rope and was alone. He climbed up 25 feet w/out a rope on a rock wall and had no way down. He held on as long as he could then let go.
he landed on his feet it would seem and sustained a pilon fx on L, L2 and L3 fx, calc fx on R.
The pilon was pretty minor. a medial mal fx and one fx thru the joint at the plafond.
THe calc fx on the other hand looked like a the calc blew out into chunks and little tiny pieces. The talus was sitting between the pieces of the cortex of the calcaneus and it was open plantarly.
For now he is in an ex-fix to maintain length.
This guy will probably not be rock climbing anymore. He will be lucky to keep his leg.
I totally understand what you are saying on the level 1 trauma situations. As I'm sure you know, Sanders, in his orig article 15yrs ago, suggested that cat4 calcs were bad news even if you somehow restored alignment. He suggested primary STJ arthrodesis in some cat4s, an option I think a lot of trauma ortho and pods might consider today. I'd be curious to know if the patient you speak of gets a left STJ AD when they ORIF the L calc and R pilon.
I've also ready primary AD suggested in many other intra-articular foot fractures... Lisfrancs, cuboid fx, even first MPJs.
What frustrates me is the clinic patients I've seen who come in with pretty routine trauma that was handled poorly at St Elsewhere. We had one of those in my school clinic last week. PER-3 six months post, and her talus was still translated way lateral on the tib... medial clear space was probably >9mm when we measured it on the digi XR. Her medial malleolar avulsion fx hadn'e even been addressed; they just plated the fibula and put in a transsyndesmotic screw (which was now backing, dehiscing, and growing MRSA at the wound site out since they didn't remove it before WB). You really feel bad for the patient in situations like that.
In school clinics and clerkships, I've also seen Hawkins 2s that were just casted (surprise... AVN!), multiple midshaft met fractures that were perc pinned and allowed to weightbear in a surgical shoe, and many of the craziest ankle alignments that make you simply say "WTF were they doing in the OR?"
Sure, posttraumatic complications happen to even good surgeons, but the lit shows us that the complications happen a lot more when the original fix was subpar. That is understandable in highly destructive pilons, calcs, and lisfrancs where the literature shows that even good alignment still has a decent chance of a bad result. In pretty routine ankles, met fx, or intrarticular foot fx need to either be handled properly or sent to someone who can, though. I'm not sure if it's egos getting in the way or just a lack of properly trauma trained docs (both pod and ortho) out there, but either way, it's bad for patient outcomes - and unfortunately, most trauma patients are fairly young with a lot of (potentially arthritic) years ahead of them.
Wanna see some truly rediculous stuff? Yes, this is a most extreme case of bad trauma fix... these are
post-ops (and pre-ops for the DPMs at the hospital). This lady fx her ankle in the Caribbean, had it fixed there, and now she's in a Miami ER a month later having medial mall pains/wound for some reason...
