NPA (negative palmar angles) are what I'd consider a plague that I see most commonly amongst Thoroughbreds. NPA is strongly linked to early shoeing in open-heeled shoes with no frog support at a young age leading to very poor caudal development and low angles. I believe other factors play a role here too, inappropriate diets causing flaring/long toes, ulcers and lack of free movement on firm ground.
NPA messes with the horse's posture putting unnecessary strain on tendons, ligaments, the musculoskeletal system and more.
This lovely horse always has me feeling a little sad when I see his feet as there's only so much one can do to improve them. I grabbed some pics at his last appointment and was thrilled to see that he'd actually made some significant gains. This also shows up in improved posture (not featured here as he was being a bit of a worm) which will have him feeling a lot better in his body. While his feet will never be perfect, this was very encouraging progress for five months since his shoes came off.
What to do about caudal failure?
*If you must shoe traditionally, look at frog support options
*Try composite shoes with built in frog support as a more ergonomic option. Your horse may appreciate the support alongside the shock-absorbing properties of composite shoes.
*Consider giving your horse a break from shoes provided you have set him up for success with a barefoot-friendly diet, trim and lifestyle. This often yields some very quick improvements and at least a couple degrees of gains.
*Use hoof boots. We have played around with 3 degree wedge pads in the boots which often results in an immediate improvement in posture. There are debates as to whether wedges are good or not and it's one I'm still exploring myself personally. I think it's fair to let the individual horse tell us what he feels.
*The last option is to not buy these horses in the first place and seek out ones with good angles and strong digital cushions.
