orthapedic MD told me once that the fibula is non load bearding. he told me that after my compound tib/fib fracture was set and the fib moved out of place about a week later.
hurt like hell when it moved but they never reset it. it healed with a bit of a bulge - but i'm still kicking 15 years later with no hitch in my gitty up!
heal fast good man... there's trail to be ridden!
