I was hit by a car some years back. Crazed yuppie
female dog came over 4 lanes and hit me from behind in an off ramp. My speed 45mph.. her speed was estimated at 80mph. I was riding an Italian Moto Morini Camel. Bike was totalled. It had 1300 miles.
Shattered my left wrist. 2 operations, pins, casting for 8 months, 2 years of therapy.
At the same time, the ball was broken off my right
humerus (sp) plus ripped up the rotator cuff. 2 surgeries, 8 months in casts, 2 years of therapy.

Yes, you can play the box after such injuries. However, the weight of the box is a consideration.
And, any technique or box configuration that will reduced the push-pull would be of benefit.
