Subject: Human Skeletal Growth / Human Skeletal ReGrowth

Note: The question that follows may require answering by a person that has more 
knowledge than basic medical Skeletal Growth knowledge. When the question is 
answered I would also like details of the answerer(s) expertise.


I am familiar with the human bodies skeletal bone growth process at the level of 
detail as it is usually explain (including other answers to similar questions on 
MadSci.Org). But my question asks at a more detailed level.

My questions are :

1. Do bones in the human body stop growing at different times (ages) ? If so which 
bones at which ages ? (More importantly/in detail, which in the later years age 15/
16+)

2. How is the human skeleton tested to see if its growth is ended/stopped/finished. 
Is there some kinda reference point that is tested ?. I refer to growth here as in 
the measurement of the skeletal length.

3. How can a bone be altered to be made to grow again once it has stopped growing. 
I mean altered back into a state of growth as in developement growth (length) and 
not repair or maintainace, surgically I presume. I do not mean  'broken'/
'stretched'.
