DIP joint inside and underside.

Yep, the injury i had was a suspected volar plate breakage.

Neither do i, it was a photo to illustrate clearly what i meant.
> Lastly, there's not much difference between crimping and pinching something (depending on the size of the pinch). The only difference is the lack of the thumb over the index - the rest of the joints are generally at the same angle as when you are crimping.
Unless very small, pinches are more of an sloper/open-handed grip.
