There is wide variation of conformation between and within different breeds, the significance of which requires expert understanding of optimal breed characteristics and potential effects on soundness or performance. If your horse's croup is higher, then your horse is built more downhill. Space between the fourth tarsal, the third metatarsal, and the fourth metatarsal bones Particular attention is warranted in evaluation of distal limb alignment, hoof quality, size, and balance due to the concentration of locomotive stresses in this area. The pastern angle (E) should be equal to the shoulder angle. Flatter Croups. She cites an example of a horse with contracted heels or a club foot in front yet a strong, symmetrical, well-conformed pelvis and hind limbs. However, this requires expensive equipment, has the health and safety implications of possible radiation exposure to personnel involved, and is very sensitive to subject positioning (Barr, 1994; White et al., 2008). The neck should tie into the horses body fairly high to provide good chest space. 3. Illustrations of some common conformational defects of the hooves (see Table 15-1 for description). Conformation refers to the shape or structure of a horse, and it can impact a horse's athletic ability. In the hindlimb, a plumb line dropped from the ischial tuberosity should touch the point of the calcaneous (prominent caudally in the tarsus or hock), follow the plantar metatarsal surface to the metatarsophalangeal joint (MTPJ or fetlock), and fall 7.5 to 10 cm (Ross, 2003) caudal to the heel in the lateral view. Advancing technology has allowed more objective, quantitative evaluation of conformation amenable to statistical analysis and aims to find evidence-based relationships among conformation, performance, and soundness. The assessment of conformation is subjective, and different people . The skeletal format will affect such factors as joint range of motion, limb arc and hoof flight patterns, and weight distribution in motion, with subsequent effects on coordination of movement (including limb interference), balance, power (propulsion, impulsion, and collection), agility, and endurance. Proximal attachment of the lateral collateral ligament of the fetlock joint to the distal end of the third metacarpal bone A horse that exhibits correct conformation should be a natural athlete. The literature presented in this chapter will follow the terminology appearing in the research papers. and has a special interest in managing the care of sport horses. From these observations, an overall proportioned symmetry in lengths and heights is desirable, both left to right and fore to hind. When assessing foal conformation, limbs can also be viewed from above at the shoulder and hip (skyline view). Here are five areas of concern that Dr. Morrow sees in rope horses that come through his practice regularly. Hindlimb 7. If the red hair comes from the bay pattern, the mane, tail, and legs will be black. Webcast | Then, stand back and look at the whole picturethe entire horsenot just the offset knee or base-narrow stance or turned-out toes, says Collatos. 2. A long hindquarter allows for increased range of extension and flexion. Reasons for performing the study: Assessment of conformation is commonly used in the selection of horses for performance purposes. Although meeting with some success, 6 of 21 traits were classified unacceptably low in repeatability (Mawdsley et al., 1996). (2006a) found measurement variations in stance within one horse to be almost as large as between horses, thus highlighting the importance of standardized repeatable positioning of the horse. There is emerging a new way of assessing conformation in the dynamic realm, until now . This point puts the horse at threat of lameness because of to instabilities in its gait or motion and way of journey. Some conformational traits are more likely to affect horses soundness and performance depending on the discipline. In horses with ideal conformation, a visualized vertical plumb line dropped from the tuberosity of the scapular spine should bisect the longitudinal axis of the forelimb to the metacarpophalangeal joint (MCPJ or fetlock) and fall 5 cm behind the heel in the lateral view. Some breeds of horse have heavier or rounder muscles than others. For this reason both Collatos and Duberstein try to avoid limb conformation that might predispose a horse to suspensory ligament desmitis (SLD, inflammation of that structure), including straight hock conformation and long cannon bones and pasterns. The lack of anatomic precision, documentation, or both limits the interpretation of some studies. The top of the neck should ideally be twice as long as the underside of the horse's neck, or a 2-to-1 ratio. unshod Standardbred horses with toed-in, toed-out and normal hoof conformation Vet J. Width of head and third metacarpal/metatarsalWidth of chest and pelvis This upsets their natural balance. These traits were hoofpastern axis in both forelimbs and hindlimbs, head size, and vertical alignment of the forelimbs and hindlimbs, all having a coefficient of variation greater than 10%. Conformation also varies with breed, within a breed and between individuals. Conformation will, therefore, partially dictate the relationship between form and function, thus modifying the potential for biomechanical efficiency, superior performance, musculoskeletal durability, and perhaps even longevity (Wallin et al., 2001). A thorough hands-on exam. 11. Whether you are shopping for a new riding prospect or already have a horse, it helps to be able to correctly evaluate conformation. Can Shoeing Improve How Show Horses Move? (See "The Triangle: A Tool for Quick, Accurate Assessment.") Judging Conformation. Briefly, relevant body observations should include head shape and size; height at the withers and croup; body length; neck length; shoulder length (top of the withers to point of the shoulder); pelvic length (tuber coxae to tuber ischii); scapular and humeral inclination; pelvic and femoral inclination; and chest width. This evaluation may be regarded as the front line for judgments when selecting horses for specific intended tasks, including breeding selection. However, opinions concerning segment lengths, joint angles, and skeletal inclinations were largely discrepant. If a horse's head is on the small side the reverse is true. There is a great need to clarify and standardize the descriptive terminology of joint alignments, as most conformational traits are described using multiple traditional and variable nonscientific terms, rather than by defining anatomic configuration. Offset knee/bench knee Also it is ideal for the foot to land directly beneath the bone column in a limb with good conformation. 5) Which line represents the length of the Femur? Too big of a head will cause the horse to be clumsy and move heavy on their front. The horse should be comfortable working at least 2 hours a day under the saddle. Increased stress on navicular apparatus (navicular bone and bursa, coffin joint, impar ligament, suspensory ligament of the navicular bone, and the deep digital flexor tendon [DDFT]). For these, quantitative conformational assessment, in addition to these traditional judging methods, has been suggested to improve predictive capability (Holmstrom and Philipsson, 1993). The veterinarian palpates the horse, checking muscles, joints, bones and tendons for evidence of pain, heat, swelling or any other physical abnormalities. Excessive bulk can cause soundness problems. Make sure your entire horse is in the photo and that he's well groomed, wearing a bridle, looking straight ahead and standing on level ground-and try to avoid distracting backgrounds. In at the knee/knock knee are bred to work cattle, and a lower headset facilitates rapid turns with exceptional speed and quickness from the hindquarters. Establishing the exact source of the alignment deviation is imperative; for example, does a laterally pointing hoof, commonly described as toed out, originate from an externally rotated limb or from a particular distal joint? Illustrations of some common conformational defects of the hindlimbs (see Table 15-1 for description). There is wide variation of conformation between and within different breeds, the significance of which requires expert understanding of optimal breed characteristics and potential effects on soundness or performance. Objective conformational evaluation provides a useful adjunct to subjective assessment by quantification of some conformational traits; however, it must be remembered that not all conformational aspects can be measured objectively. Only gold members can continue reading. Twisting of fetlocks also predisposes to arthritis. The point of ground contact has a . From the side, you should be able to draw a line from the point of the buttock, down the back of the cannon to behind the heel. Conformation usually comes into play during three events: looking at a horse to buy, looking at a horse to breed, and determining the best "job" for a horse. When considering conformation, Chrysann Collatos, VMD, PhD, Dipl. Orthobiologic Options for Treating Horses. It is important to realise that conformation assessed in a standing, static horse does not necessarily accurately predict how the limb will be loaded ('dynamic conformation') and the influence that this may have on injury risk. Regents of the University of Minnesota. Box level +/ crossbar Wherever the head moves, body weight tends to follow., Riders in many disciplines desire certain neck sets and conformation that lead to musculoskeletal issues, says Collatos. In many instances, coexisting conformational anomalies will be present, at times allowing biomechanical compensation and at other times exacerbating musculoskeletal stresses during locomotion. From these observations, an overall proportioned symmetry in lengths and heights is desirable, both left to right and fore to hind. The lack of anatomic precision, documentation, or both limits the interpretation of some studies. A good farrier balances the horse, not just the foot., In horses with limb deviations, hoof angles tend to develop imbalances more quickly than horses with good limb conformation because the way the crooked leg moves causes uneven wear on the hoof, adds Duberstein. 1. Log In or Register a > to continue 1) What conformation flaw is shown? Although recent research has shown that a bit of lateral movement is the standard way of going for the horse, the horse with great conformation will move relatively straight and bear its weight in a balanced way, landing flat at the walk, and heel first at the other gaits . Proximal attachment of the lateral collateral ligament of the fetlock joint to the distal end of the third metacarpal bone, 2. Metacarpophalangeal and proximal interphalangeal (pastern) joints have a straight appearance Square means the height from the withers to ground should equal the length of body (point of shoulder to the point of the buttocks). Distinct notch distal to the accessory carpal bone on the palmar aspect of the limb causing the circumference of the leg below the carpus to be less than that above the metacarpophalangeal joint (fetlock) When examining the conformational traits of individual limbs, a plumb line approach is useful in identifying angular or torsional deviation of segments from the vertical or horizontal at each joint level (Figure 15-4). Attachment of the long lateral ligament of the tibiotarsal joint to the plantar border of the calcaneus, 5. 3) What conformation flaw is shown? Shortened, choppy stride with potential to stumble. The evaluation of conformation has traditionally been subjective or empirical and remains the primary method of assessment. Predispose to degenerative joint disease (hock spavin) and curb (plantar ligament strain). A horse should have well-formed withers where the shoulder can attach to the rest of the body. Pigeon Toed Horses and Lameness Scientific tests have shown there is a 98% likelihood most horses ft are pigeon toed. Sickle hock/curby hock ISSN (print): 2047-9867 ISSN (online): 2052-2967. To evaluate conformation you need to take a walk around the horse, examine it close up, then again from 20-30 feet away and when the horse is in motion. Although different breeds will have feet of different shapes and sizes, it is universally and anecdotally desirable to have balanced feet positioned symmetrically under the central limb axis with a straight hoofpastern axis (the dorsal surface of the hoof wall lies parallel to the dorsal surface of the pastern region) (see Figure 15-3 and Figure 15-5). Use this figure for Questions below. good conformation. .

This has resulted in verification of some traditional empirical ideals and refuting of others, though results are often conflicting. Some common terms describing conformational alignments are defined anatomically in Table 15-1 and illustrated in Figure 15-1 and Figure 15-2. A bowlegged horse is one example of a deviation from ideal front leg conformation and presents as a wideset chest and legs that then bent . Tends to wing the feet with potential for interference injury. Good conformation is the foundation for good performance. As a horse comes into the breed ring and stands at the peak of the triangle, the judge has only three minutes to make a total assessment. As some conformational traits are dynamic and will only be apparent during ambulation, the traditional emphasis of conformational assessment as a pure description of static external appearance has been extended to include a more functional assessment of conformation during unridden and ridden gaits in some of the studies cited in this chapter. Using shoe branch extensions to attempt to twist a horses toed-in or toed-out conformation to what is considered normal can also create long-term problems, pain, and lameness. Goniometer (see Figure 15-3) When buying a new horse, we tend to look at their conformation. , as the ultimate long-distance athletes, are generally balanced front to back, with lean muscle mass and shoulder angles that optimize efficiency at moving across the ground with minimal effort or limb lift. The sacral spines are labeled S1 to S5 and the green line shows the croup angle. . The general shape or outline of an object, or the arrangement or configuration of parts of an object Horses differ in conformation, which affects how well they can perform in different events. In many instances, coexisting conformational anomalies will be present, at times allowing biomechanical compensation and at other times exacerbating musculoskeletal stresses during locomotion. The literature presented in this chapter will follow the terminology appearing in the research papers. Tied in below the knee There are three areas of a horse's body that contribute to his balance and allow him to look cohesive. Yet, most studies have employed generalized or horsemanship terms in describing conformational traits. Repetitive motion can lead to osteoarthritis development over time. The major disadvantages in using these methods are the possible errors introduced by marker placement on skeletal landmarks, particularly in the proximal skeleton, the consequent reliability of findings, and the time required to perform the measurements (Weller et al., 2006a). Some studies and studbooks have used a system of linear scoring in an attempt to quantify the repeatability of subjective evaluation (Dolvik and Klemetsdal, 1999; Koenen et al., 1995; Mawdsley et al., 1996). Yet, most studies have employed generalized or horsemanship terms in describing conformational traits. Congruent sloping angulation of the shoulder and hip is also desirable, with a proportional length of individual limbs in relation to the height and size of the body (Figure 15-3). Forward at the knee/bucked knee/over at the knee/sprung knee Radiography has also been used to measure joint angles and segment lengths. Short-Strided Horses. Base narrow Preselection of juvenile animals prior to growth completion based on conformation alone is risky. 8. Conformation can be defined as the formation of something by appropriate arrangement of parts or elements: an assembling into a whole (Websters dictionary, 1976) and equine conformation appraisal is traditionally based on the external appearance of the body shape, form or outline of the animal. There are five main criteria to evaluate when examining a horse's conformation: balance, structural correctness, way of going, muscling, and breed/sex . "Dynamic" balance is defined as that conformation that allows the foot to contact the ground in a prescribed pattern. From the rear view, you should be able to draw straight lines down the rear legs. Horses are more likely to suffer a severe injury when they fatigue, says Duberstein. This means that an imaginary line drawn down the front of the horse's pastern should continue in that line down the front of the hoof wall. Definition : Conformation refers to the shape, dimensions, and proportions of a horse, created by its musculoskeletal structure. Anatomic Description of Commonly Used Conformational Terms, FIGURE 15-1 Illustrations of some common conformational defects of the forelimbs (see Table 15-1 for description). 2. A founding study by Magnussen (1985) described the comprehensive set of landmarks listed below, and many research studies have followed this protocol or a derivative of it. All assessment of equine conformation should be conducted with the horse standing squarely (loading all limbs symmetrically) on a level surface. Other factors such as human management, environmental conditions, genetics, nutrition, temperament, training, and the health status of the horse will also have a large bearing on ultimate performance. A horses conformation is the way it is made up, its structure, how its body parts relate to each other and how it is proportioned. Within that group, lameness is often linked to foot conformation (Trotter, 2004).During lameness examination, load distribution is assessed in a static position with the horse standing squarely, as well as dynamically at walk and trot (Back and Pille, 2013). Lateral tuberosity of the distal end of the radius 5. As some conformational traits are dynamic and will only be apparent during ambulation, the traditional emphasis of conformational assessment as a pure description of static external appearance has been extended to include a more functional assessment of conformation during unridden and ridden gaits in some of the studies cited in this chapter.
