This is undesirable because the steep angle of the horse's hoof will not only change the way it moves but also makes the horse prone to foot and leg lameness. Best to have some angle to the bottom of the coffin bone to allow for proper and comfortable functioning of the hoof and its supportive parts. A straight wall, for example, may read the same as a concave wall or a convex wall when, in reality, they each have different mechanical functions. Guidelines such as 48-55° for the front feet, or 52-60° for the rear feet are not appropriate for every horse. Naturally! One foot is steep (the ‘up’ foot) and the other is of a lower angle (the ‘down’ foot). The horse is essentially overloading the rear of the hoof. Several other elements needed to be taken into consideration, as hoof angles are as varied as the horses that have them. Correct Angles of the Horse's Front Hoof. The front and hind coffin bones have very different angles, so the outside hoof should reflect that difference. Acceptable:If one drops a descending vertical line from the front edge of the cannon bone, there must be hoof directly underneath it. pressures on the tip of the hoof.

Severe P3 changes, sole extends below wall Severe P3 changes, sole extends below wall The Upright Non-Pathological Hoof An upright distal limb conformation may have a more upright hoof capsule, but it presents with an aligned bony column and is in line with a normal configuration for upright conformation. The frog can then function adequately as the The angles shown above are This will lead to interference problems and issues with lead departures and changes may be present. Allowing up to a postive. - 3/12" long from coronary band to ground. Timing is crucial to stop the digit pathological compromise before it becomes irreversible. We did a hoof survey towards the end of 2010 and were surprised to find that a large proportion of horses had what we call negative angles, or Negative Palmar Angle Syndrome. In recent years, these dorsal hoof wall angles have been proven wrong (due to the fact that the coffin bone does not sit in a ground parallel position in the hoof capsule) but what remains correct is the difference in dorsal angles between front and hind coffin bones. The angle of the pastern should be matching the angle of the hoof front so it appears a solid line \ If there are noticeable "breaks" in the line, a dip or bulge...you might be having a issue with trim following the horses anatomy. baseline angles from which to trim the horse's front hooves to its it's done carefully by a knowledgable farrier, no harm will be done to the horse. The reason is that the hoof angle should ideally mirror the angle of the coffin bone inside the hoof. The vertical load is then borne equally by all parts of the limb, from the scapular hinge, right through the carpus, and down to the ground surface of the hoof. Unacceptable: The pastern is skewed off to one side and either the medial or lateral wall is significantly more upright than its counterpart, thereby looking like a bell that has had its handle knocked to one side This produces point loads on the more upright side and can be a source of bruising and hoof abscesses. This was exacerbated in a lower angled hoof, ... Turner (2020) “there is no reason not to shoe for a correct hoof axis and a broken hoof axis can . Sometime in the previous century, someone assigned a numeric value to the angle of the toe as a reference point for farriers. Ideally, the hoof should be far enough back in the stance that a vertical line descending from the back edge of the cannon bone falls at a point where it meets in line with the apex of the heel, which, on a properly trimmed hoof, coincides with the widest point of the frog. HORSE LOGO, THE PENZANCE HORSE, THE PENZANCE HORSE logo, It sets the horse on its toes, similar to someone standing at attention and being ready to step off without the need to shift their weight forward to transition from rest to motion. Acceptable: The hoof wall, when viewed from the front, is on an even slope, both medially and laterally. by the The heel bulb areas will look flattened, the frog can appear to be prolapsed, and there may be a crevice in the frog from where it is pinching forward (which can trap thrush).

Unacceptable: The coronary band is on a plane that is more horizontal than a right angle of hoof to pastern. written permission of PENZANCE Equine Solutions. --The coffin bone should be allowed to A correctly trimmed hoof should feature each of the following favourable attributes, and none of the unfavourable ones. one to the other for balance. A horse with a very steep hoof angle when compared to its pastern angle is said to be club-footed (Figure 17). --The walls should not be higher than the This allows you to see the true relation of the pastern angle to the hoof. Now how does this apply to the outer hoof shape? Despite many complaints of lame horses… Hoof angles are a time-honored standard. However, a completely ground parallel CB will cause a negative palmar angle when hoof loads on soft ground. As I mentioned in Off His Rocker(s), many horse people place a great deal of emphasis on hoof angles. A horse hoof is a structure surrounding the distal phalanx of the 3rd digit (digit III of the basic pentadactyl limb of vertebrates, evolved into a single weight-bearing digit in equids) of each of the four limbs of Equus species, which is covered by complex soft tissue and keratinised (cornified) structures. because the extremely healthy "white line" places the coffin (pedal) bone high inside the hoof capsule. Hoof balance really means that the hoof is trimmed and/or shod for an equal distribution of the horse’s weight over the entire foot, and for minimum stress to joints and soft-tissue structures when the horse takes a step. So to achieve the correct hoof pastern angle on a donkey is a little more difficult than on a horse, because the actual junction of the widest part of the frog is a lot further back than the actual buttress of the heel that the donkey needs to walk on. rest as parallel to the ground as possible to minimize stress and This places the entire responsibility for holding the horse up on the muscles and ligaments/tendons, and, ultimately, leads to the fatigue and subsequent destruction of soft tissue. to have ground contact during movement. individual HORSESOURCE ONLINE!, THE HORSESOURCE Please keep in mind that each HOOF as well as each horse is an individual entity and must be trimmed as such.

This is most likely the result of grazing stance, whereby one foot is habitually placed further back than the other, with this foot becoming steeper. In addition hooves should be matching pairs, both front and hind, and should be neither too large nor too small for the horse. A hoof wall that has been heavily rasped, especially one that has been “over processed” (filed from the coronary band down to the ground surface), will also give a distorted reading, and cannot give a true indication of the angle of the wall. Unacceptable: If the ergot appears to be off to one side, there is a twist in the way the hoof lands and loads. …only one horse had an aligned hoof pastern axis between a hoof angle of 45 degrees and 50 degrees. other words, about 1/8" - 1/4" higher than the seat of corn. This means that, viewed from behind, the hoof and the heels do not appear to be aimed or twisted in different directions. Always consult your veterinarian or barefoot trim specialist. Subtle changes in hoof angles and lengths can help neutralize gait imperfections and as long as . slightly, (22-28*)  according to the length of the heel needed This may have been useful for horses being shod by different farriers, but, generally, unless a farrierwas previously acquainted with the horse, this value was somewhat arbitrary and often not even pertinent on the day it was assigned. Additionally, it is not desirable for the horse to have a hoof that is much more angled in comparison to the angle of the pastern. Walls should also This results in all manner of posture, as well as movement issues. Some horses appear to be more susceptible to hoof problems than others. --The Arched Quarters allow for the The Coronet band has a steeply upward angle and the profile shows a bull-nose. Hoof gauges – often a crude moveable protractor design – are notoriously inaccurate, as they can be manipulated in numerous ways, making it possible for there to be several different readings from the same foot. It is an unsound horse whose pastern is 45 degrees or less, when accompanied by a 45-degree hoof angle. Grade 1: The angle of the toe and the palmar angle of the coffin bone are 5 degrees greater in the affected foot than the opposite foot. This produces counter rotation of the limb, and leads to a number of problems – i.e. such. Bottom edge of wall is worn to a rounded bevel (mustang roll). These measurements are the same for every horse, because their coffin bones do not change. 1997-2003, All rights reserved. Determining hoof balance is a good first step for horse hoof trimming. --The hairline will vary This strains the DDFT and other supportive tissues. It is also extremely important that the horse is standing square, which means all four feet are placed so that the cannon bones are perpendicular to the ground and the feet are weighted evenly. We have been taught that the toe ought to be parallel to the pastern angle, and that the pastern ought to be parallel to the scapula. It is not intended to medicinally prescribe or diagnose in any The principle land marks to be uncovered at the live sole are the seat of corn and at the center of hoof adjacent to the hoof wall at the quarters. back 2/3rds of the hoof. --The dorsal toe wall should be around 3 Source(s): Owner of 2 beautiful TWH, SSH, RMH/X, and a KMH/X.

Always allow for the individuality of each hoof The angle of the joint surface of both the coffin bone and navicular bone can bear weight comfortably and allow for a full range of motion without overextension of the ligaments or tendons. Horse Hoof Care: Properely Balanced Equine Hooves through Angles: Hoof balance is achieved through hoof angles which may be measured via a hoof gage that measures the junction of the foot’s surface and hoof wall. ONLINE LOGO,  THE CLICKER TRAINED HORSE, THE CLICKER TRAINED Conversely, as the hoof angle is increased, the pastern angle becomes more horizontal. This is normally when we start to suspect that the conformation of the pedal bone within the hoof may well be the cause of the problem.

They should also --The 45 degree angle of the wall can range anywhere from 45 - 58 degrees. When hoof care professionals speak of “hoof angles,” they’re referring to the angle the dorsal hoof wall (at the toe) forms with respect to the ground, as shown in the following photo/diagram – Hoof Angle Measurement. By looking at the foot this way, I am able to factor in the whole leg and the whole horse. In 1754, Étienne-Guillaume LaFosse declared that the hoof should be at a low angle with the frog fully engaged. There is no such thing as a standard angle for any pastern, nor is there a standard angle for any hoof wall. excessive pressure inside the hoof at the point of dip. on each horse. The heels can then lift off at the same time as the carpus unlocks, and the pastern can then immediately go from rest to seamless break over. If the The angles shown above are baseline angles from which to trim the horse's front hooves to its natural conformation and wear. This is extremely stressful on the bones The horse will begin to move forward, yet the pastern must first rise up and pass over top of the hoof before the heels can begin to leave the ground and initiate a stride. horse. circulatory pump and shock dissipator for the hoof and lower leg. of the leg through the bones. Hoof angles can also differ due to the shape of the wall at the toe. Grade 4 – front hoof wall presents with 80+ degree hoof angle and severe dish. Acceptable: If one drops a descending vertical line from the front edge of the cannon bone, there must be hoof directly underneath it. This can be corrected by setting up the pedal bone as it would be if the hoof wall was in the correct place, then growing a new properly connected wall down from the coronary band.
