My 13 yr old daughter is going for a bone density test on Monday.  Between the ages of 7-12, she has broken bones at least 5 times.  She has been on Cortef or hydrocortone since she was 3 and was on Lupron from age 5 until just before her 13th birthday.  The number of breaks seem to be excessive to us.  I'll let you know what the tests show.
