I had carpal tunnel surgery in both hands and after the hands had healed
my
ability to grip between my thumb and the pinky was near zero.

This doesn't seem to have much effect in day to day use such as using
screwdrivers on tight screws or opening jars, but the experience suggests
to
me that you might be spot on in your theory.


That is because the carpal tunnel affect the median nerve, most of the grip
is controlled by the ulnar nerve.
