Okay.
All right, so this area here is the palm.
Now, where that trapezium, as Will mentioned a few minutes ago, that's really important because that's the joint surface that lets your thumb function, basically.
And when I saw that, it immediately was a red flag because normally you don't have joint surfaces that don't have a matching bone to articulate with, right?
And the skeleton...
Changes through life.
So let's say you were born without a thumb or something, but you still had this hand.
That wouldn't be a normal looking joint.
The joint is going to kind of atrophy if it's not being used.
And you can see that there's a kind of a pocket there that would articulate with the thumb.
So that was one of the major clues is that there used to be a thumb here, but it's just not present anymore.
This little illustration is just showing there's a wide range of motion at this joint.
It's a very distinct, distinct structure.
And just stop me if you have any questions.
Can you tell if it's been cut from this image or not really?
It's not.
I can't really tell.
It's not a very good resolution of an image to see cut marks.
At least I haven't.
Yeah, it wouldn't.
