[RC] Coffin bone growth - k s swigart

Could I get a reference for this?

What type of growing does a coffin bone do and how.

It is my understanding that the P2/P3 joint (i.e. the joint between the
coffin bone and the short pastern bone) is actually "closed" (i.e. the
bone no longer has any cartligeous growth plates) before a horse is
born.  But I am willing to confess that my understanding my be wrong.

Since horses' feet obviously grow bigger than from when they are born, I
consider it unlikely that the coffin bone does not grow at all after the
horse is born, so it would be interesting (if it no longer has "growth
plates") to know HOW the coffin bone grows.
