Looking at Bar Distortion

Here a nice little dissection video of a hoof in the way we look at hooves at our hoofcare seminar. It’s always great to see when people walk away from a seminar with enriched understanding.

A little video for you to share my excitement as I dissect a frog out to peek inside this foot!Hoof TK1www.patreon.com/hoofstudies

The key thing to understand here, but not mentioned in the video, is that some internal structures, aka pedal bone, navicular bone, and deep digital flexor tendon are descening slightly on weight bearing. When you see how little space there is from the top of the collateral groove to those descending structures, then it starts to make sense, that if the horn is not “moving out of the way”, aka is not descending as well, the soft-tissue in between will get compressed. Since this is is uncomfortable to the horse, the horse will choose not to load the back part of the hoof, i.e. it will not demonstrate a heel-first loading in movement or it will stand under when at rest. Unfortunately, this is easily mistaken for conformational issues, or we here statements like “that’s just how this horse is”, but we must realise that is a compensation issue.

The purpose of trimming such a foot must be to establish the correct deflection of the hoof capsule in the compromised araes and with that establishing comfort. This will alter the way the horse chooses to load the feet in movement and rest. In order to achieve this, the trim must focus on the internal structures and hoof deformations at corium level, rather than aiming for a certain look on the outside. Illustrated here.

  1. It looks to me like there is more overgrown bar smashed into the sole on the right side. It also looks like there is more hoof on the right-it’s wider. Is the digital cushion less developed because the weight bearing under at the hoof level is compromised due to pain? Would the dgital cushion become thicker if the bar were trimmed off of the sole? I’m just trying to correlate all of this stuff.

    1. The hoof in the video is more than likely a RH. The lateral side is more flared and slanted, with a more underrun heel. As such, the bars tend to lay over the sole more than in the medial side. The collateral groove (CG) on the medial side tends to be more upwards distorted.
      For the digital cushion (DC) to develop, the horse needs to use and load the foot correctly, aka load the heels well. With upwards distorted CG’s with full bars underneath will cause discomfort in the back part of the hoof and the horse will unload the area. As a result, the DG remains weak. When the CG contour normalises, aka straigtens out like the green line in marked up photo, then the horse will load the hoof better and the DC will strengthen.
