Question
I had a dislocation C4 and C5 also a fracture. I am walking but with greater difficulty as I get older.
I love mountain biking - do you think that this is bad for my neck ?

Answer
Wow.   Okay first there is a liabilty issue with me saying YES or NO.  That said, I am not the best per4son to say this, anyway.  If I had a set of films, an MRI and an exam and a history, I would say one way or the other.  

Do you have a doc who you can follow up with?  GET ONE!  You and I will both feel better about you biking.   Just last week I had a  patient whose husband died mtn biking.   Don't be the next guy.  Hope this note gets you to the doc.  Please let me know what they find!
