This is sort of off topic, but yes bone does grow. A TV show I saw about 20 years ago addressed this subject, among others.

An X-ray examination of LA Dodgers pitcher Don Sutton (I think) showed that the bones in his pitching arm were quite a bit larger in diameter than the bones in the other arm.
