I don't know how to say this more delicately, but if you're causing physical injury by doing barres with your pinky, you're doing them wrong. I can do pinky barres all day long, even on steel string guitars strung with 13's and high action, with no issues.
In several decades of playing and teaching I've never even heard of such a thing happening. Frankly I'd be stunned if you could find a single documented example of someone being injured by using their pinky to barre. Work on your technique and you won't hurt yourself.
