As these cartilaginous zones become obliterated, the epiphyses are said to be "closed" and no further lengthening of the bones will occur. A small amount of spinal growth concludes an adolescent's growth.

Check this website. http://depts.washington.edu/bonebio/...owth.html#long

It will give you a better insight of it...Check Growth/Remodeling tab over Long Bones. Check the animations step by step. =)
