Yesterday we were at the local practice track and my 9 yr old son who races the 85 class, had a rider go down in front of him...he went over the bars and the bike landed on him..causing a tibeal spine fracture Type II. Went to the ER and the Ortho on call did not feel comfortable to do surgery...he referred us to another sports/youth ortho, who we will c tomorrow and schedule surgery...I am just curious how long this injury will keep him off his bike...he was running second in our local tri-state series, so he is bummed about that...any thoughts?? :(
