CHAPTER 15 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 caudal to the heel in the lateral view. Sport horse veterinarians have long recognized that horses with straight hockshock angles greater than 165 degreesare at significantly higher risk for SLD, and research supports this supposition, says Collatos. Subjective assessment of conformation Conformation can, therefore, only be considered an indicator for future athletic potential. (From Mawdsley A, Kelly EP, Smith FH, Brophy PO: Linear assessment of the thoroughbred horse: an approach to conformation evaluation, Equine Vet J 28:461, 1996. A founding study by, Transition between the proximal and the middle thirds of the lateral collateral ligament of the elbow, Lateral tuberosity of the distal end of the radius, Space between the fourth carpal, the third metacarpal, and the fourth metacarpal bones, Proximal attachment of the lateral collateral ligament of the fetlock joint to the distal end of the third metacarpal bone, Center of the anterior part of the greater trochanter of the femur, Proximal attachment of the lateral collateral ligament of the stifle joint to the femur, Attachment of the long lateral ligament of the tibiotarsal joint to the plantar border of the calcaneus, Space between the fourth tarsal, the third metatarsal, and the fourth metatarsal bones, Proximal attachment of the lateral collateral ligament of the fetlock joint to the distal end of the third metatarsal bone. The aim of this study was to analyse dynamic load distribution and hoof landing patterns of sound Standardbreds. The base of the neck should be level with the point of the shoulder or higher, she says. 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. Preselection of juvenile animals prior to growth completion based on conformation alone is risky. The absence of standardized evaluation standards, lack of centralized training programs internationally, and a large source of error introduced by subjective assessment precludes sole use of this method to compare results between studies or substantiate the more complex relationships among conformation, performance, and soundness. For both the conformation and movement, young horses are shown on a triangle so they can be seen from all perspectives. Traditionally described as the metacarpus laterally deviated relative to the carpus; however, the displacement is usually in the radiocarpal joint (Ross, 2003) 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. Blemishes that do not affect these characteristics and have nothing to do with the horse's . 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. Proximal attachment of the lateral collateral ligament of the stifle joint to the femur Visual appraisal of defined criteria (the outlines and axes described above) and manual palpation of specific bony landmarks have been the basis of assessment, giving the examiner multiple three-dimensional images over a period. Transition between the proximal and the middle thirds of the lateral collateral ligament of the elbow, 5. If the red hair comes from the chestnut pattern, the mane, tail, and legs will be red. If a horse has good conformation, then their body is correctly proportioned and there are no faults. 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 (fetlock) and fall 5 cm behind the heel in the lateral view. Initial attempts to provide absolute values in conformation assessment have used the tools listed in Table 15-2 in combination with a reference marker system. Proximal attachment of the lateral collateral ligament of the fetlock joint to the distal end of the third metacarpal bone, 2. In many instances, coexisting conformational anomalies will be present, at times allowing biomechanical compensation and at other times exacerbating musculoskeletal stresses during locomotion. Weller et al. As herbivores, horses have a heavy GI tract with a very rigid spine to support that weight. unshod Standardbred horses with toed-in, toed-out and normal hoof conformation Vet J. Soft tissue fatigue develops insidiously throughout a competition; therefore, long, sloping pasterns are a risk factor for development of forelimb suspensory injury in (these) distance athletes.. The front legs support 60-65% of the horse's weight. During the 16 th century, Dutch engineers brought Friesian horses with them when they came to England, and these horses probably had the most significant influence on what became known as the Shire . 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. 6. The pastern angle (E) should be equal to the shoulder angle. A horse can best move if it has a long neck and short back. A horse with good balance always has an attractive profile, which means he appeals to the eye. Aesthetic factors such as athletic elegance, suppleness, overall balance and harmony, jumping style, and movement symmetry are necessarily subjectively based. Question 11. Space between the fourth tarsal, the third metatarsal, and the fourth metatarsal bones, 6. Stay on top of the most recent Horse Health news with, IF YOU ARE INTERESTED IN ADOPTING THIS HORSE, PLEASE SUBMIT AN ADOPTION INQUIRY VIA OUR WEBSITE: ALLABOUTEQUINE dot ORG. Conformation is a major factor in the physical soundness of a horse. Wider Definition : A more holistic definition considers the implications of form for dynamic function as well. 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 refers to the shape or structure of a horse, and it can impact a horse's athletic ability. A shorter hindquarter supports power and strength. The basics of horse conformation. The hind legs have fewer lameness issues than the front legs because they only carry 40 percent of the horses weight. Some conformational traits are more likely to affect horses soundness and performance depending on the discipline. (See "The Triangle: A Tool for Quick, Accurate Assessment.") Judging Conformation. Horses that are "well-built" and "put together correctly" are often among the top achievers in their sport. Neck and forelimb The head should meet the neck at an angle so the horse can flex at the pole and move in balance. Radiography has also been used to measure joint angles and segment lengths. highlighting the importance of standardized repeatable positioning of the horse. Examination procedures may include the following, as deemed appropriate for the situation: Taking a medical history. (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. (From Mawdsley A, Kelly EP, Smith FH, Brophy PO: Linear assessment of the thoroughbred horse: an approach to conformation evaluation, Equine Vet J 28:461, 1996.). All assessment of equine conformation should be conducted with the horse standing squarely (loading all limbs symmetrically) on a level surface. There are a few characteristics that could point to weak points in our equine's framework. . Although meeting with some success, 6 of 21 traits were classified unacceptably low in repeatability (Mawdsley et al., 1996). The walk and trot should be checked both under saddle and in hand. It is with increasing frequency that osteoarthritis is diagnosed in the mid and lower cervical vertebrae, using ultrasound and advanced imaging such as, Carpal arthrosis is more common in racehorses due to hyperextension of their carpal (knee) joints when they fatigue, says Duberstein. A careful examination of the feet of the horse . The absence of standardized evaluation standards, lack of centralized training programs internationally, and a large source of error introduced by subjective assessment precludes sole use of this method to compare results between studies or substantiate the more complex relationships among conformation, performance, and soundness. Dorsal edge of the coronary band 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. Conformation assessment should be a systematic and organized process incorporating a general overall observation of size, symmetry, musculature, posture, balance, and demeanor, followed by a more specific evaluation of conformational traits of the body, individual limbs, and feet. But correct basic conformation that promotes a sound horse works for all breeds. RELATED CONTENT | 7 Conformation Flaws: Piecing Together What We Know, Contracted heels or a club foot may predispose a horse to concussion-related foot lameness, she says. The neck should tie into the horse's body fairly high to provide good chest space. Also it is ideal for the foot to land directly beneath the bone column in a limb with good conformation. This length should be about 1/3 of the body length. The veterinarian will study conformation, balance and weight-bearing, as well as ook for any evidence of injury or stress. Muscle fatigue diminishes this stabilization ability, allowing joints to move beyond their normal range of motion, she says, and potentially causing severe and acute damage to cartilage, bones, and soft tissue. The sacral spines are labeled S1 to S5 and the green line shows the croup angle. 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. Good conformation is the foundation for good performance. Absorbs excess impact on medial (inner) limb structures. Tends to wing the feet with potential for interference injury. As the horse ages, the proportion of white hair may increase but usually not to the extent this occurs in grey horses. The entire hindlimb should be bisected evenly in the caudal view (see Figure 15-4). (2006c) also suggested that variability in judgment is affected by the limited repeatability of measurement techniques due to inaccurate identification of anatomic landmarks and inconsistent positioning of the subject. At this angle, the horse's elbow is directly below the front of the withers. are bred to work cattle, and a lower headset facilitates rapid turns with exceptional speed and quickness from the hindquarters. Carpal hyperextension due to a caudal displacement of the proximal row of carpal bones, the radiocarpal joint being <180 degrees (Ross, 2003). For example, a caudal deviation at the radiocarpal or metacarpal joint complex (knee) may be described as back at the knee, calf knee, or carpal hyperextension, none of which describes the precise origin of segmental misalignment. 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). Roan horses may have distinct or indistinct white markings. When an owner complains about tripping, subtle or inconsistent forelimb lameness, or difficulty in transitions, cervical arthritis is on my list of potential differentials., Collatos says she tends to avoid a low-set neck conformation for upper-level dressage or show jumping prospects. This line should evenly split the forearm, knee, cannon, fetlock, pastern and hoof. Therefore, Quarter Horse conformation tends to be downhill with tremendous power and musculature in the sacrum, hips, and thighs to enable them to dig in, turn, and go. This fact sheet will outline criteria that can be used to evaluate conformation of horses. In Ross MW, Dyson SJ, editors: Diagnosis and management of lameness in the horse, Philadelphia, PA, 2003, WB Saunders, p 21.) 6) Which line represents the length of the Hip? Large formed hocks are better at absorbing concussion and generally make for a sounder joint. Horses that have spring of rib: The back transfers the force and driving power from the hind legs. The shoulder and pastern angles should be between 40 and 55 degrees. The entire hindlimb should be bisected evenly in the caudal view. 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. Lack of symmetry will stress those points and may harm or limit the horses ability to perform with grace and ease. This means that it is affected by both many genes and the environment. (From Mawdsley A, Kelly EP, Smith FH, Brophy PO: Linear assessment of the thoroughbred horse: an approach to conformation evaluation, Equine Vet J 28:461, 1996). The general shape or outline of an object, or the arrangement or configuration of parts of an object When evaluating the conformation of a horse, you should consider the following areas: balance, muscle, structural correctness, and breed and sex characteristics (Figure 1). Coronet Band: a ring of soft tissue just above the hoof. And, armed with that knowledge, you can take steps to help keep him sound. A horse's head needs to be in proportion to the rest of their body. Tools of Conformation Measurement Conformation Quiz. But the front versus rear leg lameness tends to relate to overall horse use. Horses with poor conformation may be at higher risk of: The basic conformation rules allow you to review a horses athletic ability for a certain performance. The segment lengths of specific long bones of limbs should also be noted at this time. Regents of the University of Minnesota. There is no published data relating dynamic conformation to biomechanical loading. Email Practical.Horseman@EquiNetwork.com or mail a print to Conformation Clinic, Practical Horseman, 656 Quince Orchard Rd., Suite 600, Gaithersburg, MD 20878. A horse that exhibits correct conformation should be a natural athlete. Study with Quizlet and memorize flashcards terms like Static conformation, Dynamic conformation, What is a way to help predict lameness in a horse? Conformation. The lack of anatomic precision, documentation, or both limits the interpretation of some studies. Some common terms describing conformational alignments are defined anatomically in Table 15-1 and illustrated in Figure 15-1 and Figure 15-2. Generally, a horses neck should be one and a half times the length of the head. 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. Veterinarian conformational assessment should particularly focus on the presence of any such faults and the relationship of these faults to existing or potential pathologic conditions (Rossdale and Butterfield, 2006). After assessment, overall observations can be related to desirable or benchmark breed-specific conformational characteristics and judgment made on the horses suitability to a given career. Center of the anterior part of the greater trochanter of the femur, 3. This finding was supported by a study comparing radiographic and visual assessments of hoofpastern conformation in Warmblood foals (Kroekenstoel et al., 2006).Visual assessment was only in agreement with radiologic evidence in 6 of 92 (6.5%) evaluations. Abnormal or crooked front legs can lead to lameness by putting stress on the following. 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%. Two British Columbia Horses Test Positive for EIA, Scientists Validate Safety of Equine Blood Flow Restriction. The success of a horse in any equine discipline or industry is not dependent on perfect conformation, as this does not guarantee performance or soundness, and imperfect conformation does not necessarily exclude a horse from performing at elite levels. Illustrations of some common conformational defects of the hindlimbs (see Table 15-1 for description). When buying a new horse, we tend to look at their conformation. Shortened stride length and a more jarring gait for a rider. Jumpers, reiners, and cutting horses are prone to. Horses are more likely to suffer a severe injury when they fatigue, says Duberstein. The point of ground contact has a . 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? Her book, All Horse Systems Go, is a comprehensive veterinary care and conditioning resource in full color that covers all facets of horse care. Bruising, corns, and quarter cracks of medial aspect of the hooves from excess impact. 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. Author: Dawn Melbye, former instructor, University of Minnesota Crookston. Log In or, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on Google+ (Opens in new window), 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. Concussion is the force that travels up the leg each time the hoof hits the ground and if excessive, leads to injuries and conditions such as ringbone (a disease of the pastern joints). 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. Weller et al. Conditioning a horse properly goes a long way toward delaying the onset of fatigue, and using leg protection can help prevent interference injuries. Splayed, feet move forward in larger inward arcs "winging! Many times what riders are creating is just the appearance of suppleness, however, with energy/impulsion never really coming from behind and the horse not stepping up under himself and moving into the bridle properly. Transition between the proximal and the middle thirds of the lateral collateral ligament of the elbow "A long or short neck may affect the way the horse rides but it will . Long or short neck. Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)Click to share on Google+ (Opens in new window) FIGURE 15-3 Measurement of shoulder length (A), rump length (B), shoulder angle (C), and rump angle (D). It is the arrangement of muscle, bones, tissue, and overall body structure that come together to create the horse and the resulting athletic ability of said horse. Definition : Conformation refers to the shape, dimensions, and proportions of a horse, created by its musculoskeletal structure. All assessment of equine conformation should be conducted with the horse standing squarely (loading all limbs symmetrically) on a level surface. Strain on inner hock joint structures predisposes to osteoarthritis. It should be round with muscle to provide a smooth contoured shape. 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. While theres no such thing as perfect conformation, certain structural qualities and alignments are more likely to support soundness than others. 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 caudal to the heel in the lateral view. All horses should be evaluated walking and trotting before and after trimming/shoeing. Only gold members can continue reading. If skeletal bones articulate (join) correctly, the line of concussion that runs up the leg when the horse hits the ground is evenly distributed all the way up the limb, explains Kylee Jo Duberstein, PhD, associate professor of equine science at the University of Georgia, in Athens. Developing a horses entire body to be strong at the center and balanced from front to back helps overcome many conformational problems.. How to Choose the Right Calories for Your Horse, Respiratory Equine Herpesvirus in Pennsylvania Barn, Podotrochlosis: Navicular is No Longer the End of the Road for Horses. You can think of this by comparing a Warmblood to a Quarter Horse. Assessing limbs, feet, and body can help you and your veterinarian identify anatomical traits that could end up being performance-affecting liabilities. Short-Strided Horses. Related Prepurchase recommendations and perceived animal value rest highly on this assessment. For global advancement in this area of study, it is clearly imperative to use universally comparative methodology, which is somewhat lacking. They are more prone to stress and injury than the hind legs. Major areas to focus on are balance, muscling, type and way of going. This allows the horse to be more flexible, balanced and collect more naturally. Notably, the definition and number of traits evaluated, the point scale scoring system of conformational traits, and the image of an ideal phenotype varies greatly among registries, organizations, and countries; therefore, specific classification is essential for comparative evaluations. Despite these limitations, subjective evaluation can be easily and quickly performed by an experienced evaluator, expediting the assessment of large numbers of horses within a short time frame. Excessive bulk can cause soundness problems. 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]). and has a special interest in managing the care of sport horses. Proximal end of the tuber coxae Increases winging of hoof flight with potential for interference injury. The evaluation of conformation has traditionally been subjective or empirical and remains the primary method of assessment. Whether barefoot or shod, the resilience to withstand the stresses of competition and to achieve athletic longevity is enhanced by a balanced foot, says Collatos. Name of breed: Shire Country of origin: England Breed origin: The Shire is a breed of draught horse that originated in England in the 17 th century. ACVIM, of High Desert Equine, in Reno, Nevada, says watching a horse in motion always trumps looking at him standing still. Initial attempts to provide absolute values in conformation assessment have used the tools listed in Table 15-2 in combination with a reference marker system. 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). 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? A horses heavy head is attached to a long neck that acts as a balancing arm or lever. This line should run from the point of the buttock to slightly inside the hock, to the middle of the hoof. More than 65% of the traits exhibited large (CV > 10%) phenotypic variation within the sampled population. Louise Dentith MSc, Senior Lecturer, Moulton College discusses the limbs and dynamic conformation of the horse. So, it is sensible to avoid conformational problems like being calf-kneed (back at the knee), which potentially exacerbates hyperextension of these joints. ACVIM, of High Desert Equine, in Reno, Nevada, says watching a horse in motion always trumps . Although meeting with some success, 6 of 21 traits were classified unacceptably low in repeatability (Mawdsley et al., 1996). Visual appraisal of defined criteria (the outlines and axes described above) and manual palpation of specific bony landmarks have been the basis of assessment, giving the examiner multiple three-dimensional images over a period. Key Takeaways. Yet, most studies have employed generalized or horsemanship terms in describing conformational traits. An important ratio to consider when evaluating a horse's conformation is the ratio of the top of the neck to the bottom of the neck. Dynamic load distribution and landing patterns play an important role in equine orthopaedics. (From Mawdsley A, Kelly EP, Smith FH, Brophy PO: Linear assessment of the thoroughbred horse: an approach to conformation evaluation, Equine Vet J 28:461, 1996). This finding was supported by a study comparing radiographic and visual assessments of hoofpastern conformation in Warmblood foals (Kroekenstoel et al., 2006).Visual assessment was only in agreement with radiologic evidence in 6 of 92 (6.5%) evaluations. 2. The assessment of conformation is subjective, and different people . When considering conformation, Chrysann Collatos, VMD, PhD, Dipl. Uneven feet Hindlimb When a horse stands square, they should have a shoulder angle between 40 and 55 degrees. When assessing foal conformation, limbs can also be viewed from above at the shoulder and hip (skyline view). This evaluation may be regarded as the front line for judgments when selecting horses for specific intended tasks, including breeding selection. She has also authored the books Go the Distance as a resource for endurance horse owners, Conformation and Performance, and First Aid for Horse and Rider in addition to many veterinary articles for both horse owner and professional audiences. Extra ribs allow for a shorter back, which results in stronger coupling of the loin area. This results in uneven distribution of concussion each time the limb impacts the ground, with one area of the bone, joint, or soft tissue structures assuming excessive impact., She cautions against getting hung up on absolutes such as which conformational flaw is better or worse than another. The hindquarters influence the horses capacity for: The gaskin and thigh muscles power running, jumping and other forward movements. Judging and Conformation of Horses By: Carey Williams, Ph.D. - Rutgers University Graphics courtesy of: US Pony Club Manual of Horsemanship Book 1 Balance 1. Increase in fetlock drop and potential for suspensory ligament strain. The conformation or inherent anatomic structure of the horse is an integral part of the equine musculoskeletal constitution and will influence the quality of dynamic performance. Measurements Taken Good conformation always starts with balance. For these, quantitative conformational assessment, in addition to these traditional judging methods, has been suggested to improve predictive capability (Holmstrom and Philipsson, 1993). If your horse's withers are higher, your horse has uphill balance. 12. Despite considerable anecdotal information, there is still a considerable lack of evidence-based quantification of conformation assessment and the relationships among conformation, performance, and orthopedic health. The pastern angle (E) should be equal to the shoulder angle. and more. The conformation or inherent anatomic structure of the horse is an integral part of the equine musculoskeletal constitution and will influence the quality of dynamic performance.
