You could try using Ab Straps for movements like Horizontal Cable Rows. Hook them around your upper arm and pull from the elbow to take your grip completely out of it.
Anything where you can hook a velcro cable to your wrist? My gym has velcro attachments for use on cable machines.
Of course leg machines, lateral raise machines…
Or something like this - maybe you can improvise.
Good luck! Hand injuries are hard.
