Palmar digital should block navicular bursa, distal sesamoidean, DDFT/DDFT sheath, digital cushion, Corium, palmar 1/3 of the sole, palmar coffin joint, palmar distal phalanx, and of course the skin.
It’s not super specific but it is generally the heel, yes.
Interestingly this horse was overdue for a trim from his usual 5 weeks by 2 weeks when he was done last. It was a scheduling problem too. I strongly suspect the shoes are what got us here but I can’t back that up.
Vet wants to see a wedge or an egg bar, believes that will fix the problem right away, by fixing the NPA.
On x ray sole depth was good:
LF sole depth 18.4mm
LF heel height 15.5mm
LF toe length 40mm
LF break over 21.6mm
LF medial heel 15.9mm
LF lateral heel 21.2mm
So there is a lateral imbalance, too much toe, too-long break over.
The RF is actually worse on the toe length and break over.
