Farriery involves the skilled practice of hoof care and shoeing in horses, focusing on the maintenance and management of equine hooves. The process includes trimming and balancing the hooves, as well as the application of horseshoes when necessary. Farriery plays a role in supporting the overall health, performance, and comfort of horses by addressing issues related to hoof growth, structure, and function. Various techniques and materials are employed to accommodate different hoof conditions and activities. This page compiles peer-reviewed research studies and scholarly articles that explore the methodologies, materials, and implications of farriery in equine health and welfare.
Bras RJ, Redden R.Foot-related lameness is one of the most frequently encountered problems in the equine industry. Therapeutic shoeing is a frequently used preventative discipline for the treatment of many causes of lameness. The primary goal for therapeutic applications is to offset the mechanical limitations and enhance the healing environment. Equine podiatry is a blend of the 2 highly respected professions each contributing to the task at hand, but neither formally educated and trained as collaborative team members with a common thread of podiatry principles.
Stutz JC, Vidondo B, Ramseyer A, Maninchedda UE, Cruz AM.Therapeutic farriery is part of the management of certain orthopaedic conditions. Non-podal parameters are important as most horses shod with therapeutic shoes are expected to perform again and the choice of shoe type may be influenced by the effects they may have on gait. The aim of this prospective study was to evaluate the effects of three different shoe designs and unshod front feet on forelimb non-podal kinematic variables using an extremity mounted inertial measurement unit (IMU) system under conditions of treadmill and overground exercise on a soft geotextile surface at the trot. Ten so...
Lynden J, Ogden J, Hollands T.Emerging research highlights how, due to demographic changes in horse owner populations in Western societies, complex owner-horse relationships are leading to inappropriate horse care, including overnutrition, which in turn can lead to laminitis. Farriers, due to their regular visits, may be in a position to support owners in dealing with this problem. Objective: This study explored whether UK farriers have a role in working with horse owners to support horse welfare and prevent laminitis. Methods: Grounded theory analysis, a qualitative methodology. Methods: Semi-structured interviews were co...
Hagen J, Kojah K, Geiger M, Vogel M.Corrective shoeing is used to change hoof angulation with the intention to influence the angulation of the digital joints to reduce strain on associated tendons. The objective of this study is to examine how gradual changes in hoof angulation affect the dorsal metacarpophalangeal joint (DMPJ) angulation and cross-sectional areas (CSAs) of the deep digital flexor tendon (DDFT) and superficial digital flexor tendon (SDFT) concerning the individual toe conformation. Forelimbs of 30 horses were examined barefoot and equipped with 5°, 10° and 20° toe wedges (TWs) and heel wedges (HWs). Phalangea...
Faramarzi B, Nguyen A, Dong F.Appropriate hoof preparation and symmetry are linked to the well-being of the horse. Previous studies have shown the efficacy of pressure plates (PPs) in delivering objective biomechanical analysis. We aimed to assess the effect of hoof trimming on hoof biomechanics using a PP. Nine clinically sound Arabian horses were walked across a PP while foot strike was recorded by a digital camera. Kinetic and kinematic parameters were recorded before and after trimming. Changes were considered significant when ＜ 0.05. Vertical force ( = 0.026) and contact pressure ( = 0.006) increased after trimming...
Stevenson K.As a recipient of the Worshipful Company of Farriers' equine veterinary studies award, Edinburgh vet student Karis Stevenson got the opportunity to learn firsthand what farriers do. She spent a week with Stephen Newman near Paisley. Here, she gives a snapshot of what she learnt.
Sprick M, Fürst A, Baschnagel F, Michel S, Piskoty G, Hartnack S, Jackson MA.To evaluate the damage inflicted by an unshod hoof and by the various horseshoe materials (steel, aluminium and polyurethane) on the long bones of horses after a simulated kick. Methods: Sixty-four equine radii and tibiae were evaluated using a drop impact test setup. An impactor with a steel, aluminium, polyurethane, or hoof horn head was dropped onto prepared bones. An impactor velocity of 8 m/s was initially used with all four materials and then testing was repeated with a velocity of 12 m/s with the polyurethane and hoof horn heads. The impact process was analysed using a high-speed camera...
O'Grady SE.Hoof care in the first few months of life is serious business and should never be taken lightly. Farriery plays a vital role in both the development of the hoof and the conformation of the limb. Management of the feet and limbs during this period will often dictate the success of the foal as a sales yearling or mature sound athlete. A sound foot care program is time-consuming, whereas assembly-line trimming is quick and easy, but the former is much more beneficial.
Leśniak K, Williams J, Kuznik K, Douglas P.Variation in equine hoof conformation between farriery interventions lacks research, despite associations with distal limb injuries. This study aimed to determine linear and angular hoof variations pre- and post-farriery within a four to six week shoeing/trimming interval. Seventeen hoof and distal limb measurements were drawn from lateral and anterior digital photographs from 26 horses pre- and post-farriery. Most lateral view variables changed significantly. Reductions of the dorsal wall, and weight bearing and coronary band lengths resulted in an increased vertical orientation of the hoof. ...
Holzhauer M, Bremer R, Santman-Berends I, Smink O, Janssens I, Back W.Information is scarce on the prevalence of hoof disorders in horses. In this study, we examined the prevalence of and risk factors for hoof disorders in a population of horses in The Netherlands. In a group of 942 randomly selected horses, hoof health was scored during regular foot trimming (one horse/farm). Hooves were assessed for the occurrence of one of 12 hoof disorders by a group of 21 certified farriers in two periods i.e. winter and summer of 2015. The mean age of the group of horses was 11.2±5.6years. They were mainly used for recreation (28.2%), dressage (26.8%), other disciplines (...
Pauwels FE, Rogers CW, Wharton H, Flemming H, Wightman PF, Green RW.Hoof balance radiographs are commonly used as the basis for corrective farriery decision-making in horses, however there are limited published data quantifying effects of the stance of the horse or the horizontal radiographic beam angle. In this analytical study, the influence of variation of the horse's stance in the craniocaudal and lateromodial plane on hoof balance measurements as well as the influence of variation of the horizontal radiographic beam angle on dorsopalmar hoof balance measurements was examined. Distal left thoracic limb lateromedial radiographs were acquired using a standar...
Dahl VE, Hitchens PL, Stover SM.OBJECTIVE To determine the effects of racetrack surface and shoe characteristics on formation of wear grooves in the horseshoes of racehorses. SAMPLES 1,121 horseshoes from 242 Thoroughbred racehorses collected during routine horseshoeing procedures at 4 racetracks with dirt or synthetic surfaces. PROCEDURES Data for 1,014 horseshoes from 233 racehorses were analyzed. Horseshoes were photographed, and length and width of grooves formed at the heels of the solar surface of horseshoes were measured on the photographs. Effects of racetrack, racetrack surface, and shoe characteristics (eg, shoe si...
Buckley P, Buckley D, Coleman GT, Morton JM.To describe preventive health care provided to a cohort of Pony Club horses in rural New South Wales, Australia, and the associated veterinary involvement. Methods: Prospective longitudinal study Methods: Observational data collected for 48 Pony Club horses using daily owner-kept diaries and monthly veterinary visits for 9-12 months. Results: Frequency of healthcare events varied markedly between the horses; 54% of horses received 5 or more foot-care treatments, 69% received 1-3 anthelmintic treatments, 40% received dental care, 21% received chiropractic care; only 8% were vaccinated. Farriers...
Panagiotopoulou O, Rankin JW, Gatesy SM, Hutchinson JR.Horse racing is a multi-billion-dollar industry that has raised welfare concerns due to injured and euthanized animals. Whilst the cause of musculoskeletal injuries that lead to horse morbidity and mortality is multifactorial, pre-existing pathologies, increased speeds and substrate of the racecourse are likely contributors to foot disease. Horse hooves have the ability to naturally deform during locomotion and dissipate locomotor stresses, yet farriery approaches are utilised to increase performance and protect hooves from wear. Previous studies have assessed the effect of different shoe desi...
Pfau T, Daly K, Davison J, Bould A, Housby N, Weller R.Military working horses perform a high proportion of work on road surfaces and are shod frequently to deal with high attrition rates. The authors investigate the influence of shoeing on movement symmetry as an indirect indicator of mechanical differences affecting force production between contralateral limbs. In this quantitative observational study, inertial sensor gait analysis was performed in 23 Irish sport type horses (4-21 years, 1.58-1.85 m) in full ceremonial work at the King's Troop, Royal Horse Artillery. Changes in two movement symmetry measures (SI: symmetry index; MinDiff: dif...
Amitrano FN, Gutierrez-Nibeyro SD, Schaeffer DJ.OBJECTIVE To determine and compare the effect of hoof boots (HBs) and shoes with a toe extension on stance duration, ground reaction force, and sole length in contact with the ground in nonlame horses during walking. ANIMALS 6 nonlame Standardbreds. PROCEDURES Force plate gait analyses of the forelimbs were performed while the horses were walking barefoot before manipulation of feet (baseline), while the horses were walking fitted with HBs, while the horses were walking shod with toe-extension shoes, and while the horses were walking barefoot after shoe removal. Horses underwent radiography of...
Thieme K, Ehrle A, Lischer C.Knowledge of the normal radiographic anatomy of the equine foot and the relationship between the distal phalanx and the hoof capsule is imperative for objective assessment of hoof health. Little information is available for the hooves of ponies. The aim of this study was to establish a database of reference values for normal ponies and to investigate the relationship between the height at the withers and radiographic measurements of the hooves. Radiographic examinations were performed on 81 ponies, ranging from 81.5 to 148.0 cm height at the withers, immediately after foot trimming. Eighteen p...
Caldwell MN, Allan LA, Pinchbeck GL, Clegg PD, Kissick KE, Milner PI.This study used a UK trimming protocol to determine whether hoof balance is achieved (as defined by equivalence of geometric proportions) in cadaver limbs (n = 49) and two cohorts of horses (shod, n = 6, and unshod, n = 20; three trimming cycles). To determine equivalence, dorsal hoof wall length (DHWL), distance from the heel buttress to the centre of pressure (HBUT-COP) and distance from dorsal toe to centre of rotation (DT-COR) were calculated as a proportion of bearing border length (BBL) using digital photography. Geometric proportions were tested using Fieller's test of equiv...
Häsler S, Dängeli J.Saint Eligius became the saint patron of farriers and veterinarians in the 13th century. This was first mentioned by Jordanus Ruffus, emperor Frederic the 2nd's equerry, who refers to a gregorian hymnal dedicated to Eligius. The legend says that Eliguis amputated a horse's foot, shoed it and placed it back on the horse's leg. This legend might have replaced the Germanic cult described in the incantations of Merseburg. In Switzerland the veneration of Eligius is particularly spread in the canton of Lucerne. Der Heilige Eligius wurde im 13. Jahrhundert Schutzpatron der Hufschmiede und Tierärzte...
Waldern NM, Wiestner T, Ramseier LC, Amport C, Weishaupt MA.Tölt is a symmetric four-beat gait with a speed range extending into that of trot and canter. Specific shoeing methods, such as unnaturally high and long hooves, are used to enforce individual gait predisposition. The aim of this study was to assess the consequences of this shoeing style on loading and movement of the limbs at walk, tölt and trot, and at different velocities. Simultaneous kinetic and kinematic gait analysis was carried out at walk (1.4m/s) and at two tölting and trotting speeds (3.3m/s and 3.9 m/s) on an instrumented treadmill. Thirteen sound Icelandic horses were first mea...
Weishaupt MA, Waldern NM, Amport C, Ramseier LC, Wiestner T.To enhance expressiveness of forelimb movement and improve the four-beat rhythm of the tölt, Icelandic horses are commonly ridden with excessively high and long hooves. The aim of this study was to objectively assess the effect of shoeing on intra- and inter-limb coordination and limb movement consistency (inter-stride variability) at walk, tölt and trot. Thirteen sound and fit Icelandic horses accustomed to exercise with a rider on a treadmill were assessed with long and high hooves commonly used for competition (S(H)) and with the hooves trimmed according to the standards of normal shoeing...
Arndt JL, Pfau T, Day P, Pardoe C, Bolt DM, Weller R.Hoof testers are commonly used in equine practice. In this study, we determined the intraoperator and interoperator reliability of force application with hoof testers for different groups: experienced veterinarians, novices and farriers. For this purpose, we have developed and validated an instrumented hoof tester. Forces varied significantly between the different regions of the foot for experienced operators applying the highest forces to the heels, then the frog, then the toe, and the lowest forces to the quarters. Novices applied significantly more force to the toe versus the frog. Intraope...
Spaak B, van Heel MC, Back W.It was shown that rolled-toe shoes smooth hoof-unrollment and thereby reduce peak loading of forelimbs in trotting Warmblood horses. Shoe design and shoeing technique for hind feet have been modified over recent decades from fully fitted, toe-clipped shoes to set-back, side-clipped shoes. Objective: To study the effects of different shoe modifications on loading and movement of the hind hoof. Methods: Ten clinically sound Warmblood horses were shod with 3 types of hind shoe: first, fully fitted, toe-clipped shoes, followed randomly by side-clipped shoes without a rolled toe that were set back ...

O'Grady SE.Proper farriery promotes a healthy functional foot and biomechanical efficiency and prevents lameness. Because the equine veterinarian is responsible for the soundness of the horse, a working knowledge of farriery becomes essential. A thorough knowledge of traditional horseshoeing enables the veterinarian to interact with the farrier at the farrier's level; this ultimately enhances and promotes quality hoof care. This article focuses on fundamental farriery and recognizing subtle changes in hoof conformation that can be used to preserve the integrity of the hoof capsule, along with the structu...
Peel JA, Peel MB, Davies HM.The economic impact of soundness problems in racehorses is very high and low hoof angle at the toe has been associated with a lack of soundness. However, it is not clear what environmental and management factors might contribute to a low hoof angle. Objective: To investigate the hypothesis that the hooves of racehorses become flatter when in gallop training, as well as to determine factors contributing to this trend. Methods: Weekly hoof measurements were taken with a hoof gauge from 45 Thoroughbred racehorses; 4 Thoroughbred show horses kept in consistent conditions and shod by the same farri...

Mohite DS, Sheikh CS, Singh S, Kalita J, Williams S, Compston PC.Farriery is a critical component of healthcare services for working equids. However, in India, an informal workforce, lack of structured training facilities and non-implementation of farriery regulations pose challenges for quality farriery. Brooke India, an equine welfare organisation, has undertaken many initiatives aiming to improve farriery services, including technical training and engagement with equid-owning communities. However, this has met with varying success. The study aimed to identify factors that prevent farriers providing quality farriery services. Focus-group discussions were ...
Roepstorff L, Johnston C, Drevemo S.The objective of this study was to validate a simple method to measure the mediolateral expansion of the heels and to apply this method in an in vivo experiment. It was also the aim to quantify the mediolateral expansion in different areas of the heel using an in vitro model. In the in vitro study, 5 right and 5 left distal forelimb specimens from 5 Standardbreds were mounted vertically in a custom-made compressive test machine. The heel expansion was measured using optical kinematic analysis and a potentiometer system. Specimens were tested unshod, with frog pressure and with the weightbearin...

Clayton HM, Gray S, Kaiser LJ, Bowker RM.To monitor changes in hoof morphology in response to barefoot trimming. Methods: Seven horses were trimmed every 6 weeks according to barefoot trimming principles, which involved levelling the hoof to live sole, lowering the heels, bevelling the toe and rounding the peripheral wall, while leaving the sole, frog and bars intact. A 4-month period was allowed to lower the heels sufficiently to achieve a hoof shape representative of the barefoot trim. This was regarded as the starting point for morphological adaptations in response to maintenance of the trim. Hoof morphology was measured from late...
Dabareiner RM, Carter GK.In conclusion, horses with heel or navicular area pain vary, and no one treatment option is suitable for all horses. Each horse must be evaluated individually to determine which structure in the palmar aspect of the foot is injured, severity of disease, horse and hoof conformation, and horse use and level of performance expectation before a treatment plan can be developed. Overall, there are many treatment options to help these horses to perform their intended athletic event.
Hinterhofer C, Stanek C, Haider H.A finite element (FE) hoof capsule was built as a small, symmetrical forelimb hoof on IDEAS* as a model for calculation and visualisation of stress and displacement of the equine hoof capsule. The model's loading was performed according to the suspension of the coffin bone within the hoof wall (pulling force) and over the sole and frog (compressing force) with a total of 3000 N. Restraints of the model's ground nodes and surface wall nodes were defined for simulation of 4 shoeing situations: a regular horseshoe, a horseshoe with a toe clip, a horseshoe with regular side clips and a horseshoe w...
Malone SR, Davies HMS.This crossover study tested the hypothesis that hoof shape would differ after a seven-week period of horses ( = 11) wearing shoes versus barefoot. An ANOVA appropriate to a crossover design was used to assess the differences in the change in hoof shape over the seven-week period and significance was set at < 0.05. Results are displayed as the mean difference for horses when shod versus barefoot ± the SEM for the left (L) and right (R) front hooves. Proximal hoof circumference (PHC) decreased when horses were shod and barefoot, but this decrease was greater when horses were shod (L -0.65 Â...
van Heel MC, van Weeren PR, Back W.Overload injuries in sport horses commonly occur; shoeing techniques are believed to be important in prevention of these injuries, but there is a paucity of scientific information identifying the potential connection. Objective: To test a horseshoe with a modified rolled toe designed to ease the process of breakover and decrease loading of lesion-prone structures of the distal limb. Methods: Twenty clinically sound Warmblood horses trotted over a track containing a pressure/force measuring system and 6 infrared cameras. The horses were measured with 2 types of shoes, standard flat shoes and sh...

Turner TA.Navicular disease was diagnosed in 36 horses. Each horse was treated, using shoeing as the only major means of treatment. Phenylbutazone was used initially for 10 days after shoeing. Shoeing was designed to correct preexisting problems, enhance physiologic function of the foot, and ease breakover of the foot. The horses were evaluated over a period ranging from 12 to 54 months. The lameness improved in all horses. Thirty-one of the 36 horses treated were not lame when last evaluated. Shoeing was most effective when performed within 8 months of the first signs of lameness. Also, horses used for...
Benoit P, Barrey E, Regnault JC, Brochet JL.The purpose of this study was to compare the damping effect of 16 types of shoeing by measuring hoof acceleration parameters on two trotting horses. At impact, maximal deceleration had extreme values such as 188 m/s2 (+/- 55) for the most damping combination (p < 0.01) and 746 m/s2 (+/- 14) for the steel shoe (mean = 551 m/s2 +/- 125). After the shock, the hoof was exposed to a mean vibrating acceleration at 418 Hz (+/- 84) which was progressively damped in 37.3 ms (+/- 10.5). According to these results, the damping ability of different farriery products significantly reduces (p < 0.05) shocks...
Moyer W.Hoof wall defects in horses are common occurrences, and, fortunately, many of those detected present little or no danger to the individual horse. Those defects that are either presently a problem or have a great likelihood of being a problem do often require specialized consideration. Horse shoeing and farriery are ancient practices; over the years, a multitude of methods, theories, and management schemes have been proposed. It is unfortunate to note that few studies are available to provide an accurate incidence rate, a better understanding of the various causes, and, lastly, a comparative ap...
Turner TA.Navicular syndrome can be treated in a variety of ways. This is related to the fact that it has a variety of causes. Prognostically, most horses will improve with treatment. One can expect about 50 per cent of the horses to become useably sound for 1 year, no matter what treatment is used. The disease is progressive, and affected horses eventually will need to be retired because of lameness. The author's therapeutic approach is to utilize shoeing as the primary therapy. Shoeing is performed to correct structural problems and to ensure that shoeing is physiologically sound. Nonsteroidal anti-in...
Thomason JJ.Objectives were to examine the deformation of the healthy equine front hoof during locomotion, by recording strains on its outer surface, and to test whether its mechanical behaviour is significantly altered under different locomotory conditions and variation in hoof shape. Strains were recorded in vivo from 5 rosette gauges around the circumference of the right forehooves of 12 horses. The magnitudes and orientations of principal strains at the midstep were compared statistically for different conditions of shoeing (shod vs. unshod), gait (walk vs. trot), substrate (treadmill vs. ground), and...
Kummer M, Gygax D, Lischer C, Auer J.Hoof preparation and shoe fit are integral to the long term soundness and athletic ability of horses. The farrier influences the balance of the hoof by both the trimming and the shoeing procedure. The goal of this study was to investigate and quantify the influence of the farrier on hoof parameters by trimming. Forty Warmblood horses ranging in age from 6-12 years and withers height 162-172cm were included. They were divided into six groups consisting of six or seven horses each, shod by one of six different farriers. The hoofs of the horses were radiographed twice using a standardised method ...
Willemen MA, Savelberg HH, Bruin G, Barneveld A.Toe weights are applied to influence the stride characteristics of trotters. The quantitative effect of 88-g toe weights on the stride characteristics of Standardbred trotters was evaluated in a kinematic study using a CODA-3 analysis system. Six trotters were studied at a speed of 11 m/s on a treadmill. Temporal gait variables, joint angles, and the trajectories of the forelimb hoof were calculated. The stride patterns of the individual trotters were assessed by a judge and compared to the CODA-output. Those trotters with poor flexion of the carpal joint during the swing phase or with insuffi...
Pauwels FE, Rogers CW, Wharton H, Flemming H, Wightman PF, Green RW.Hoof balance radiographs are commonly used as the basis for corrective farriery decision-making in horses, however there are limited published data quantifying effects of the stance of the horse or the horizontal radiographic beam angle. In this analytical study, the influence of variation of the horse's stance in the craniocaudal and lateromodial plane on hoof balance measurements as well as the influence of variation of the horizontal radiographic beam angle on dorsopalmar hoof balance measurements was examined. Distal left thoracic limb lateromedial radiographs were acquired using a standar...
Kuwano A, Tanaka K, Kawabata M, Ooi Y, Takahashi T, Yoshihara T, Reilly JD.A survey was carried out into white line disease in 1781 Thoroughbred racehorses kept in stables at the Japan Racing Association (JRA) Miho Training Center (MTC) September-October 1996. The survey was conducted while horses were being shod by farriers. The horses that still exhibited damaged white lines after regular trimming were diagnosed as having white line disease. The factors recorded were age, sex, number of diseased horses, number of diseased hooves, number of lesions by region over the bearing border of the hoof and the classified length of such lesions. The percentage of total diseas...
Chateau H, Degueurce C, Denoix JM.Understanding of the biomechanical effects of egg-bar shoes remains incomplete because kinematic studies are usually performed on hard tracks and with skin markers that do not measure the actual 3-dimensional (3D) movements of the 3 digital joints. Objective: To quantify the effects of egg-bar shoes on the 3D kinematics of the distal forelimb in horses walking on a sand track. Methods: Four healthy horses were equipped with ultrasonic markers fixed surgically to the 4 distal segments of the left forelimb. The 3D movements of these segments were recorded while the horses were walking on a sand ...
Pleasant RS, O'Grady SE, McKinlay I.Conditions that result in the loss of the structural integrity of the hoof wall, such as quarter and toe cracks, are not uncommon and usually manifest in lameness. The successful management of these problems involves identifying and addressing the underlying causes, stabilization of the foot, and committed follow-up.
van Heel MC, van Weeren PR, Back W.To determine the mechanism that enables horses to partially counteract the shift of the center of pressure under the hoof induced by changes in hoof morphology attributable to growth and wear during a shoeing interval. Methods: 18 clinically sound Warmblood horses. Methods: Horses were evaluated 2 days and 8 weeks after shoeing during trotting on a track containing pressure-force measuring plates and by use of a synchronous infrared gait analysis system set at a frequency of 240 Hz. All feet were trimmed toward straight alignment of the proximal, middle, and distal phalanges and shod with stan...
Eustace RA, Caldwell MN.This paper describes the treatment of 10 horses suffering from acute laminitis using the heart bar shoe and a dorsal hoof wall resection technique. All cases had progressed to prolapse of the tip of the pedal bone covered by solar corium through the horny sole; in one case the exposed tip of the distal phalanx became visible. Nine cases of distal phalangeal rotation and one case of distal displacement of the distal phalanx (sinking) are described. Two animals were destroyed because of the degree of lameness, one remains slightly lame at the trot and the remaining seven have returned to their p...
Hunt RJ.Underrun heels are common and involve hoof capsule distortion in which the horn tubules of the heels undergo bending and lengthening, resulting in decreased strength and functionality. The syndrome varies in clinical presentation, depending on duration, severity of distortion, presence of secondary problems, and presence of lameness. Primary treatment goals are to maintain soundness and functional integrity of the foot and to establish a normal hoof capsule. Resolution of the problem is generally not achieved in horses in a heavy work schedule, and realistic goals in this situation are to main...
Sharp Y, Tabor G.Links between poor hind hoof balance, pathologies in the hind limb and associated altered posture have been suggested but not quantified. The hoof is proposed as a neuro-sensory organ responsible for informing equine stance with implications for musculoskeletal health in the hind limb and trunk of the horse. This study aims to quantify equine limb posture and its relationship with hoof balance. Twelve horses presenting with negative plantar angles were photographed and limb posture documented before and after the creation of positive plantar angles and improved three-dimensional proportions ar...
