The hand will never be 100% but it should work with a release trigger. I lost some flexibility because the tendon adhered to the flesh. But he skin graft saved the day. I'm ok with the deal. Just cannot make a fist. With either hand now. I can still grip, but not closing the fingers to the palms.
Jack, would any "rice therapy" help? I believe many baseball pitchers, pro and otherwise work their fists in a bucket of rice..plunge the hand in etc. But I imagine you are taking some kind of physical therapy?
