Hi @PasMarra thank U 4 your request - on Thursday 26.02.2026 afternoon @edersonferrante will work on the left hand for the other issue and he will check if intervention may be combined on that opportunity.

You might want to recalibrate the OC joint, but that's just my two cents

I redid the thumb tendon because it wasn't very functional when opening or closing, after redoing it in both directions, it worked correctly, as you can see in the attached video.
