Dr. Corenman,
I have a follow up question regarding using a bike for exercise. Your patients resume riding outside at 12 weeks. Do you allow a more normal flexed position on the bike at that time? Sometimes a fall can occur,In your opinion would this bone be at more risk than others at this point? You say 16 weeks before climbing, is this due to the greater effort or the extra motion while standing? Thanks for your advice with this topic.
