Wow,
Schefty posted JPP's actual medical chart. That's a big deal and the hospital will get into serious trouble over this, with certainty of lawsuit for millions.
With that info, looks like JPP had a "ray amputation", which
is explained here with pictures. Basically, they're going to take out all remaining parts of the index finger, so he can use the middle finger for handgrip instead.
From the article,
"However, conversion to a ray amputation can narrow the palm and result in a loss of grip strength and pronation strength.. [They] found that power grip, key pinch, and supination strength are diminished by approximately 20% of normal with index ray amputations.[19] Pronation strength is diminished by 50% in the same group of patients. "
The end result is-- JPP will likely come back, but his handgrip will be weaker. I suspect he'll still be quick but the grip strength may limit a little of what he was able to do before.
