Son Just Had Bone Age Done Of Left Wrist At

Son just had bone age done of left wrist at 14 years & 11 months. In the past year he grew approximately .75 inches. His current height is 5 feet 5 inches tall. My husband is approx. 5 feet 7 inches and I am approximately 5 feet 2 inches tall. His bone age results show it resembles male standard #28-29 and a skeletal age of 16-17. However, it does not mention whether the bones have fused. Do you know whether there is an chance of anymore growth potential? Thanks!
