Hi there!

With the knee x-rays the bone age seems around 16-18 years. With the other X-ray as well, there is no ‘gross’ delay and I would not worry much as well. I assume the growth hormone deficiency has been confirmed and documented by appropriate serial tests and you may benefit with the treatment.

As for the predicted height this is a formula used to calculate height in normal individuals and may need to be adjusted for growth hormone deficiency. Also the coefficients described in the formula are race and population specific, based on normal charts and it would not be possible for me to calculate these for you. You may however request your doctor, if he/ she could provide a rough estimate.
Hope this helps.

Take care!
