What are they? Do they have the same effect as egg bars. What do you use them for? Are there any detrimental effects. Said horse goes fabulously in egg bars but specialist is concerned about heal crushing long term and mentioned straight bars. Can you please tell me every thing you know about straight bars the good and the bad.
Heel crushing results from toe leverage opposing the ground forces in the heel. Straight vs. egg bar shoe choice ought to be determined by the needs of the horse. The results should be evaluated at every appointment to determine if the baseline is improving, steady, or deteriorating. Usually that evaluation is done by the person shoeing the horse.
I rarely see egg bar shoes here...maybe it is all the mud we have (trouble enough keeping regular shoes on!). I have had straight bar shoes on my horses at different times for different problems. One was a horse with white line that was cut out, so he was missing a large chunk of hoof...bar shoes were put on to help distribute the weight and provide more support while the hoof grew out. Another horse had coffin joint issues that responded well to the extra support of bar shoes and pads. He did not have any heel crushing issues, but I also kept him on a fairly short cycle (5 weeks or less) and my farrier is super skilled and attentive. He wore them for years while in work, and I only put him back in regular shoes while languishing at home (which he has been fine in, but he's just turned out).
I took specialist to mean some sort of vet that is a lameness specialist? When discussing shoeing changes, if possible, I get my vet and farrier together, even if just with a phone call. I've had my vet and farrier here working side by side with x-rays and horse at hand when we dealt with a founder case (might have done straight bars then too? I can't remember!). Depends on the personalities of the people involved, as I know some farriers and vets don't always get along, but all mine do!
