Looks impossible, my thumbs don’t bend that way. Hopefully nobody being abused has similar thumbs.

  I know someone who has that same issue. They started having other wrist/thumb issues, and only realized they had limited range of motion in their thumbs while doing Physical Therapy. The PT didn't help them get more range of motion, just helped reduce some pain they were having.

  Really? You can’t wrap your fingers around your thumb like that? I am not a flexible person and I can do it easily. It’s the same thing as making a fist with your thumb inside it (not usually a good idea!).

    Like depicted in that picture, no; close enough to work, probably. I can't do this ( https://openheart.bmj.com/content/openhrt/2/1/e000169/F5.large.jpg https://openheart.bmj.com/content/openhrt/2/1/e000169/F5.lar... ) because the joint at the base of my thumb doesn't bend that way much at all. I can't do this ( https://www.medmd.org/wp-content/uploads/2016/11/Bend-Your-Thumbs.jpg https://www.medmd.org/wp-content/uploads/2016/11/Bend-Your-T... ) because I can't bend the tip of my thumb while keeping my fingers straight. The index and middle finger bend with the thumb tip. I can do what this picture describes as opposition ( http://i2.wp.com/boneandspine.com/wp-content/uploads/2016/09/thumb-movements.png http://i2.wp.com/boneandspine.com/wp-content/uploads/2016/09... ) with a combination of little finger movement and straight thumb or bent thumb and clawed fingers, and so I can make a fist with my thumb rotated around and tip covered by fingers.

    It's the same move people usually do spontaneously when they're walking out in the cold and/or rain.
