Its a little peanut shapped bone in the wrist that only has blood suply from one end. I broke mine in half so 1 end of the bone has no blood suply to it so it aint healing :ahhh: so it looks like i have to go under the knife soon.
I done it at one of the last race's of the season i was trying to make a pass on a off chamber corner and went in a bit to steep and went straight into the ground.I took a handle bar end to my chest which fractured my cartilege of my sternmum and also hit my head :) .
