Hope that you don’t mind me replying to all. Here are 2 companion cases of patients with chronic Monteggia injuries – the first looks similar to yours Hilary and the 2nd has the annular ligament flipped backwards and the AL and brachialis are interposed between the radial head and ulna.

I sure do love this group and what I’m learning is so so good. I will try to contribute more as I am loving the comradery. When you are not in an academic setting, these conversations are few and far between!!
From:
I’m no expert on elbow dysplasia….but I am not a veterinarian.
Say What????
After Ken Schreibman wrote to ask if I had access to contralateral elbow XRs (I do not, I doubt they were done…the ones I shared were from outside), I did a quick search about elbow dysplasia.
Try it.
It is apparently rampant in many breeds of dogs….and, in those affected, it is bilateral in 80%
I kept changing the search terms to include the words "human" or "people"…but it stubbornly refused to bring up any images or references on elbow dysplasia in humans!
I’m thinking the apparent "dysplasia" is simply remodeling from 1 month of dislocation.

So there is volar dislocation of the Radial Head
The red arrow points to what seems to look a lot like a flipped bucket handle meniscal tear, but this is not the knee (What is that???)
Is it just a markedly thickened anterior capsular plica? (I thought those were lateral)
I’m not seeing the posterior annular ligament well, but I don’t know if it’s gone or just really attenuated
XRs shared by the referrer
Another question
There was an acute injury with onset of symptoms 1 month ago by history
But the RH looks a bit blunted and the adjacent proximal ulna seems a bit deformed—-is that remodeling from chronic dislocation, or was there underlying dysplasia?
