Happened to me this year w/ my Oneida - 10 years of constant shooting, the yoke cable came aprart at full draw (while practicing from a treestand). I was glad I had my harness on, a bow coming apart at full draw, kind of makes you jump back a bit.
luckily, I was not injured.

Sorry to hear it happended while hunting and that you were hurt. Hope you get back on the horse, if it seems to be a problem, consider a different style bow.
