Hairline Fracture?

Thanks for the reply. The injury was a result of direct impact with a rock as a result of falling off my mountain bike. Doc said to walk with a cane to help me get around, increase load bearing as I could manage. Doc said I must have hit it very hard to break a healthy bone. I am a triathlete, so weight bearing exercise and calcium intake apparently helped make this less of an injury than it could have been if my bones were not strengthened by training and diet.

I waited until injury plus 21 days to ride spin bike, I am a very experienced cyclist (experienced with fixed gear riding which in some ways has similar char' to spin bike) so I am very careful not to fight the flywheel or put major stress on the bone. No pain at all from the injured area on spin bike, now have four hours riding on it with no negative symptoms. I do feel like I lost some cardio fitness in three weeks though. Easier to get my heart rate up and keep it up than it was pre injury.

I'll still walk with a cane to keep the injury from stress most of the time until I go see Dr again next week.

ROM in injured ankle is improving with each spin bike session. I'll start stretching soon, taking it very easy.

I have fractured my Tibia.  The break was so small that it was not diagnosed from the first set of x-rays in the ER.  Only a week later (after I walked around on it for a week) did the two parallel lines about an inch apart (perpedicular to the length of the tibia) show up on x-ray.  The break is completely non-displaced and seems stable.  The Dr did not cast it or put me in a boot so I am assuming he thinks it is plenty stable.  He told me to get crutches or a cane and stay off it as much as possible and come back in 4 weeks.
