The foot being ripped of is not how the foot would be lost, either David's
explanation of ripping/tearing of tendons or of the fishing line cutting into
the flesh leading to infection and then gangrene are how I had been led to
believe the foot/leg could be lost from fishing line. I'll see if I can find
some sort of reference for it but gangrene makes sense to me.
Cheers,
Chris
