Hoof injured at coronet band

[Montannna@aol.com]

Hi,

I have a horse that hit its hoof in some mysterious way to knock a 1 inch by 
1/2 inch chunk out at the top of the coronet band.  I have it wrapped and 
have been treating with furazone/DMSO.  The vet told me it would cornify 
within about 3 weeks but will take 8-12 months to fully grow out.  I am 
wondering if it will be strong enough to subject to trail conditions.  Does 
anyone know of a way to protect this area of the hoof as it grows out?  Or if 
I even need to protect it?

Thanks,
