I want to sum up the responses in this case. The hand surgeon claims that there is a trapezium dysplasia and a subluxation in the CMC-joints.
I also think there is an unexpected subluxated appearance in the 1. CMC joints, but I am not experienced with trapezium dysplasia.
I received this link from Volker Lapczynski, with some illustrations that are quite suggestive:

Some of you agreed with this once I mentioned the possibility, but only 1 commented initially on the subluxation appearance rather than the brachydactyli.
On the other hand (pun intended), others are in doubt:
I see this all of the timeI have been told by a hand surgeon in other cases that it was "nothing"
I think it depends on the clinical context
I don’t think the trapeziums (trapezii?) look abnormal. lateral subluxation of 1st CMC joints could be due to ligamentous laxity. Consider SLE, Ehlers-Danlos, etc
So, I am not sure about this case, but will have a focus on this bone from now on…
Thanks, everyone!

A lot of people immediately point out the brachydactyli, I did not see that (and the symptoms were not there either). Actually the symptoms are from the 1st ray, some hypermobility, weak thumb pinching bilaterally, associated with some pain.
I am not sure here – so happy to get input. Ingrid Kjellin mentioned already to me that there appears to be subluxation of the 1st CMC joints. Is there a trapezium dysplasia? (This is what the hand surgeon claims)
I decided to give you this view as well:
Hi again
History withheld. The hand surgeon says that the primary "Normal findings" description is not correct. I think I agree, but let’s hear if anyone has any opinion?
There were other projections as well, but this is what you get!Best,
