Never say "avoid trails" ! My last bone breakage was 4 years ago at age 50 ( femur in 4 places, now have 24" rod in the leg, pins clamps etc) at Morris Bridge, so it is not about the trail. Stuff Happens, regardless of the type of trail you ride.
And yes I have broken many other bones in my younger years, colar bone twice, once doing Moto and once on MTB. If you don't get it plated, make damm sure you wear the harness pulled TIGHT or you will end up with a big hump where it broke, gotta make sure it is held together as much as possible.
PS. You will be back and should ride all trails, I do not avoid any trails because of past crashes or injuires.
My name is Frank and yes I have broken my arm( needed plates and screws) on my namesake trail @ Alafia and yes I ride it today. ( Ok, if truthful, I was actually off of the Frank's Loop trail a little when I did it)
By the way, Sand Pine still rides the SandPine trail too, where he broke one of his bones.
