My son is 9 and was just diagnosed with an advanced bone age.

My son just turned 9, and was just told he has a bone age of a 12 1/2 to 13 year old.  He has not started puberty yet.  Is there anything we could or should be doing besides monitoring him.? I'm just so scared for his self confidence.  He has always been the tallest in his class, but his dad is 6'5".  Is it possible that all boys that are taller than their classmates just have a more andvanced bone age?  My husband just continues to believe that it is no big deal.  When we go back for our next bone scan, will we find that his bones have aged even more?

If his bone age is equal to his height age, I think he should be fine.  How you figure this out is get a height growth chart, plot your son for his age and height he is now.  Where your plot is for your child you go straight across toward the higher ages until your line is at the 50%.  Look down to see what age this turns out to be, if it is 12 1/2-13 years, then he should be fine.  Just means he is going to be a tall boy!! Let me know if you need help figuring this out.

Thanks for responding.  He is in the fifty percentile range for a 12 1/2 year old.  I'm trying to remain positive that this is normal for big boys with big dads.  We are still waiting on blood work to come back.
