your in luck...well not really.
your in luck becuase I can give you the straight dope on this fracture
I am an Orthopaedic tech at Mass general hospital.
the same guys that prolly put your son in the cast.
this is one of the MOST aggrivating fractures out there.
it takes the longest to heal.
the schapoid actually gets it healthy blood supply on the way BACK to the heart. its one of the only bones in the body to do this.
which is why we see people in casts for extended amounts of time.
depending on what kind of Fx we are talking here, communuted, transverse, ect ect you might be looking at 2 months in a cast..maybe more.
I suggest a very healthy diet, no smoking (if he is older) and be very careful on the pain meds of choice, certain ones slow down healing even more.
usually tylenol is the way to go.
this is a goo oppertunity to work the OTHER arm.
and by NO MEANS should you play in the cast.
its there to hold the fracture in place, NOT protect the fracture.
hope this helps/
