Trauma in horses encompasses physical injuries resulting from accidents, falls, or other external forces. These injuries can range from minor cuts and bruises to severe fractures and internal damage. Trauma can affect various systems within the horse, including the musculoskeletal, respiratory, and gastrointestinal systems. The response to trauma involves complex physiological processes, including inflammation and tissue repair. Veterinary assessment and management of equine trauma often require a multidisciplinary approach to address immediate care and long-term recovery. This page compiles peer-reviewed research studies and scholarly articles that explore the causes, effects, and treatment strategies for trauma in horses, providing insights into diagnostic techniques, therapeutic interventions, and rehabilitation practices.
Imai S, Sato R, Fujiwara R, Terui S, Kimura A, Ichijo T, Kasashima Y, Miyazaki T.A 15-year-old Thoroughbred gelding was presented for examination due to chronic corneal opacity in the right eye, which had been noted for several years. An ophthalmic evaluation revealed dense, irregular corneal opacity; an absence of the direct pupillary light reflex; and a positive dazzle reflex. Fluorescein staining was negative and cytology of a corneal conjunctival swab identified nucleated squamous epithelial cells, but no inflammatory cells. Slit-lamp examination failed to visualize intraocular structure, and the lesion was deemed to be chronic and irreversible. An obstacle-avoidance t...
Schmidt S, Swagemakers JH, le Jeune SS.The cervical vertebral column in horses plays a crucial role in movement, posture, and performance and disorders affecting it can cause pain, ataxia, or lameness. This review discusses major acquired (traumatic, infectious, neoplastic) and degenerative (osteoarthritis, foraminal stenosis, intervertebral disc disease) conditions. Acquired lesions often arise from trauma, bacterial infection, or neoplasia, with clinical signs ranging from neck pain to neurologic deficits. Degenerative disorders, particularly osteoarthritis of articular process joints, are common in the caudal cervical spine and ...
Dos Santos TS, Dillmann JB, Giovelli M, Elias GO, Lima RK, Cescon S, Stainki DR, Dos Santos RC, Corrêa C, Monteiro SG.This study reports the successful use of maggot therapy in four horses with traumatic wounds caused by wire fences, treated in veterinary clinics and under field conditions in southern Brazil. All lesions showed tissue necrosis, purulent discharge, and foul odor, indicating infection and delayed healing. Sterile Lucilia cuprina larvae (L1 stage) were applied directly to the wounds for 48 hours. Rapid improvement was observed, with marked reduction of necrotic tissue, exudate, and odor, and stimulation of granulation tissue in three cases. Complete wound closure occurred between 10 and 60 days ...
Boije Af Gennäs K, Jungmalm J.Although horse riding is hazardous and injuries are common, young riders regularly engage in horse-related activities. To our knowledge, there have been no syntheses on youth horse-related injuries published during the past decade that employ a multi- and interdisciplinary research agenda (M-IDR) and that incorporate both quantitative and qualitative methods. Therefore, this scoping review aimed to (1) review studies on horse-related injuries among children and adolescents and (2) identify methodological and paradigmatic trends according to M-IDR. Using the Preferred Reporting Items for System...
Loder RT, Walker AL, Blakemore LC.IntroductionAmputations and avulsion injuries due to horse-associated activity are rare, yet they can result in significant impairment. The purpose of this study was to further investigate such injuries using a national emergency department database.MethodsThe US National Electronic Injury Surveillance System (NEISS) was used to identify horse-associated amputation and avulsion injuries occurring between 2000-2023. Demographic data of age, sex, and injury details were collected.ResultsThere were 34,091 emergency department visits for equine-associated injuries, with 120 (0.35%) due to amputati...
Weixler VHM, Aldana-Aguirre J, Zaulan O, Chin V, Guerguerian AM, Mertens L, Honjo O.We present 2 cases of traumatic ventricular septal defects (VSDs), both caused by horse kick injuries. Given this rare but critical condition, we decided to share our experiences and the lessons learned managing these cases. Methods: The first patient, a 12-year-old girl, was trampled by a horse, sustained a traumatic apical ventricular septal defect with pseudoaneurysm, was stabilized first, and underwent surgical closure 19 days after the injury. The second patient, a 9-year-old girl, was kicked by a horse in the chest; developed profound cardiogenic shock; and was found to have multiple lar...
Fletcher KA, Benedetti B, Limon G, Grist A, Padalino B, Hernández-Gil M, Gibson TJ.There has been limited research into the effectiveness of penetrating captive bolt (PCB) for stunning horses () at slaughter. This study observed 100 horses at a commercial abattoir in Mexico, stunned using pneumatic PCB. Animals were assessed at the time of stunning and immediately after for signs of effective/ineffective stunning and shot positioning, with macroscopic gross brain pathology conducted to determine brain trauma. Twenty-five percent (25/100) received more than one shot and 28% (28/100) displayed behavioural signs of ineffective stunning. Of these 28 animals, all had deviations o...

Cordonnier T, Germon V, Lemé C, Jouve JL, Launay F, Pesenti S.Despite benefits in children, sport practice has been reported with higher risk of fractures. Our objective was to report the characteristics of sport-related fractures in children and to compare them to fractures sustained in a domestic context. Our hypothesis was that sports-related fractures more frequently required surgical treatment, and could therefore be considered more severe METHODS: We conducted a retrospective cohort study including patients under 16 years old, diagnosed with a fracture at the emergency department, excluding skull and face fractures. Demographic data, context of inj...
Loder RT, Walker AL, Blakemore LC. Equestrian activities can result in spine injuries. Most studies are from single centers, and none use a national database. It was the purpose of this study to describe the demographics, injury mechanisms, and types of equestrian-associated spinal injuries using a US national ED database. The National Electronic Injury Surveillance System database was queried for equestrian-related spine injuries from 2000-2023. ED disposition was categorized as discharged or not discharged. Statistical analyses accounted for the weighted, stratified nature of the data to obtain national estimates. There we...
Tay A, McMaster M.Equine tendon lacerations are not uncommon secondary to traumatic wounds and degloving lacerations. These wounds are often contaminated and, therefore, basic principles of wound assessment and management are critical to identify the extent of an injury. Ancillary tools to aid physical examination include radiography, ultrasonography, and synoviocentesis (eg, if involving a joint and/or tendon sheath). Prolonged convalescence period, continued external coaptation, and controlled exercise are mainstays of treatment following tenorrhaphy. A poor prognosis for return to full athletic function is e...
Maeda Y, Kanno C, Sugiyama M, Yamamoto R, Sato S, Ando R, Noda R, Kawaguchi H, Takahashi F.A 17-year-old Thoroughbred stallion died suddenly after grazing. Necropsy revealed massive hemorrhage in the pericardial sac, suggesting cardiac tamponade. Aortic perforation was observed at the aortic origin, and hemorrhage was observed in and around the epicardium. Superficial observation of the aortic lumen revealed a transverse tear of the aortic wall at the bases of the right semilunar valve and septal semilunar valve. Fibro-osseous changes with calcification were histopathologically observed at the site of the rupture. A nodular goiter was observed in the left thyroid gland. The horse di...
Martinez-Saez L, Marín-García PJ, Llobat ML.Osteochondrosis (OC) is a frequent manifestation of developmental orthopaedic disease, and its severe clinical presentation is known as OC dissecans (OCD). OC is defined as a disruption of the endochondral ossification process in the epiphyseal cartilage, and this disease has been reported in different mammalian species, including humans, dogs, pigs, and horses. OCD is an important cause of lameness in sport horses and is a common cause of impaired orthopaedic potential, whose clinical signs may be of minimal magnitude or manifest as severe joint effusion or clinically noticeable lameness. The...
Swezey E, Szydziak E, Angus LDG, Mehta V, Cardozo-Stolberg S.Equestrian trauma is recognized as a high-risk injury mechanism with the potential for significant morbidity and mortality. Although horse-related injuries are more frequently seen in a rural environment, they can also occur in urban settings. Urban physicians should be mindful of these potential cases.

de Oliveira Ferreira LV, Maia L, de Andrade DGA, da Costa Kamura B, de Carvalho M, Amorim RM.Cell-based therapy has emerged as a promising strategy for treating peripheral nervous system (PNS) injuries across different species. However, there is a scarcity in the literature regarding the transplantation of mesenchymal stem cells (MSCs) for treating PNS injuries in horses. This report aims to describe the therapeutic potential of equine MSC transplantation in two horses with chronic traumatic facial nerve paralysis. Both horses presented with lip ptosis and right deviation of the nostril and upper lip, being clinically diagnosed with left facial nerve paralysis. Due to the refractorine...
Valberg SJ.Although horses most commonly develop exertional rhabdomyolysis, there are numerous causes for nonexertional rhabdomyolysis (nonER) that pose a serious health threat to horses. Their etiologies can be broadly categorized as toxic, genetic, inflammatory/infectious, nutritional, and traumatic and a variety of diagnostic tests are available to discern among them. This study discusses causes of nonER as well as diagnostics and treatments that are specific to each etiology. General treatment of acute rhabdomyolysis is covered in detail in the study in this issue on sporadic and recurrent exertional...
McGowan C.Traumatic muscle injuries are likely to be frequent in athletic horses yet are often overlooked. These injuries usually involve internal (intrinsic) trauma, and particularly occur in athletic horses exercising at higher intensities, at unaccustomed workloads, or performing work requiring sudden acceleration, deceleration, and/or direction changes. These injuries can present with signs ranging from acute pain and lameness in a localized region to unexplained elevations of muscle enzymes on routine blood tests with or without poor performance. They include exercise-induced muscle damage such as ...

Stumpfe MC, Horch RE, Müller-Seubert W.Pressure ulcers are a persistent and growing challenge in modern medicine, with prevalence rates ranging from 3.4% to 32.4% globally. Demographic changes suggest an increasing number of patients at risk, emphasizing the need for effective prevention and advanced treatment strategies. These ulcers, particularly stages III and IV, often require surgical intervention due to severe tissue damage. Among the surgical options, the Posterior Thigh Flap has emerged as a reliable fasciocutaneous flap, frequently referred to as a "work-horse flap", for defect coverage in the ischial region. To improve ou...
Drahonovska A, O'Neill HD. The objectives of this study were (1) to evaluate the need for flexed radiographs of the proximal medial trochlear ridge (PMTR) after trauma involving medial tarsus; (2) to evaluate outcome following arthroscopic removal of traumatic osteochondral fragments (TOCF) resulting from direct injury to PMTR. Methods: Records of patients with wounds to the medial tarsus were searched and those with TOCF of the PMTR included.

Willis AT, Dahlgren AR, Woolard KD, Ghosh S, Donnelly CG, de la Concha-Bermejillo A, Pacheco A, Watson KD, Berryhill E, Aleman M, Wensley F....In 2020, a novel neurologic disease was observed in juvenile Quarter Horses (QHs) in North America. It was unknown if this was an aberrant manifestation of another previously described neurological disorder in foals, such as equine neuroaxonal dystrophy/equine degenerative myeloencephalopathy (eNAD/EDM). Objective: To describe the clinical findings, outcomes, and postmortem changes with Equine Juvenile Spinocerebellar Ataxia (EJSCA), differentiate the disease from other similar neurological disorders, and determine a mode of inheritance. Methods: Twelve neurologically affected QH foals and the...
Ytrehus B, Carlson CS, Ekman S.Osteochondrosis is a common and clinically important joint disorder that occurs in human beings and in multiple animal species, most commonly pigs, horses, and dogs. This disorder is defined as a focal disturbance of enchondral ossification and is regarded as having a multifactorial etiology, with no single factor accounting for all aspects of the disease. The most commonly cited etiologic factors are heredity, rapid growth, anatomic conformation, trauma, and dietary imbalances; however, only heredity and anatomic conformation are well supported by the scientific literature. The way in which t...
Ball CG, Ball JE, Kirkpatrick AW, Mulloy RH.Horseback riding is more dangerous than motorcycle riding, skiing, football, and rugby. The purpose of this study was to identify the incidence and injury patterns, as well as risk factors associated with severe equestrian trauma. Methods: All patients with major equestrian injuries (injury severity score > or = 12) admitted between 1995 and 2005 were reviewed. A 46-question survey outlining potential rider, animal, and environmental risk factors was administered.

Giles RC, Donahue JM, Hong CB, Tuttle PA, Petrites-Murphy MB, Poonacha KB, Roberts AW, Tramontin RR, Smith B, Swerczek TW.Pathology case records of 3,514 aborted fetuses, stillborn foals, or foals that died < 24 hours after birth and of 13 placentas from mares whose foals were weak or unthrifty at birth were reviewed to determine the cause of abortion, death, or illness. Fetoplacental infection caused by bacteria (n = 628), equine herpesvirus (143), fungi (61), or placentitis (351), in which an etiologic agent could not be defined, was the most common diagnosis. Complications of birth, including neonatal asphyxia, dystocia, or trauma, were the second most common cause of mortality and were diagnosed in 19% of the...
Johnson RA, Albright DL, Marzolf JR, Bibbo JL, Yaglom HD, Crowder SM, Carlisle GK, Willard A, Russell CL, Grindler K, Osterlind S, Wassman M, Harms N.Large numbers of post-deployment U.S. veterans are diagnosed with post-traumatic stress disorder (PTSD) and/or traumatic brain injury (TBI), leading to an urgent need for effective interventions to reduce symptoms and increase veterans' coping. PTSD includes anxiety, flashbacks, and emotional numbing. The symptoms increase health care costs for stress-related illnesses and can make veterans' civilian life difficult. We used a randomized wait-list controlled design with repeated measures of U.S. military veterans to address our specific aim to test the efficacy of a 6-week therapeutic horseback...
Padalino B, Hall E, Raidal S, Celi P, Knight P, Jeffcott L, Muscatello G.Equine transportation is associated with a variety of serious health disorders causing economic losses. However; statistics on horse transport are limited and epidemiological data on transport related diseases are available only for horses transported to abattoirs for slaughter. This study analysed reports of transport related health problems identified by drivers and horse owners for 180 journeys of an Australian horse transport company transporting horses between Perth and Sydney (~4000 km) in 2013-2015.

Norwood S, McAuley C, Vallina VL, Fernandez LG, McLarty JW, Goodfried G.Injuries from encounters with large animals represent a significant health risk for rural communities. We evaluated our regional trauma centers' experience with large-animal injuries to determine whether certain mechanisms and patterns of injury predicted either major head/craniofacial or torso (chest/abdomen/pelvis) trauma. Methods: The hospital courses of 145 patients with injuries related to large animals were reviewed retrospectively to determine patterns of injury, specific injury mechanisms, species-specific injuries, and predictors of multiple body region trauma. Results: Seventy-nine p...
Flecknell P.The last decade has seen continued progress in both the recognition and management of animal pain. This upsurge in the use of analgesics in animals is welcome, but the main areas of use continue to be the control of postoperative or post-trauma pain, and the management of musculoskeletal pain, in companion animals and horses. The management of pain associated with other conditions, such as soft-tissue inflammation or cancer, is still relatively neglected. Pain management in farm animals, and in animals used in biomedical research could also be improved further. Apart from providing some intere...
Abu-Zidan FM, Rao S.Horse riding and handling are uniquely dangerous. Knowledge of the risk factors of horse-related injuries is essential to prevent them. We aimed to define the factors that affect the severity of horse-related injuries and the length of hospital stay. A number of 231 patients (136 females and 95 males) with horse-related injuries were studied. A generalized linear model was used to test the effect of age, sex, cause of injury, complexity of the mechanism of injury, year, place of injury and profession of the injured, on the injury severity score (ISS) and the hospital stay. Fall from a horse wa...
Jeffcott LB.This paper reviews current developments in equine osteochondrosis complex and the clinical syndromes associated with it. Although the primary lesion has been defined as a failure of endochondral ossification, its definitive cause is unknown and appears to involve heredity, growth rate, nutrition, mineral imbalance, endocrinological dysfunction and biomechanical trauma. Despite the international importance of osteochondrosis in horses, surprisingly few controlled investigations have been performed on its pathogenesis. The studies that have been conducted suggest that local effects on differenti...
Ekman S, Carlson CS.Osteochondrosis is a disorder of epiphyseal cartilage about which there is considerable confusion in the literature. We believe that this is due to the fact that osteochondrosis has been studied in the chronic stage when the lesions are morphologically complicated and the initial causative insult is impossible to determine. The etiology of osteochondrosis appears to be multifactorial, with trauma, hereditary factors and rapid growth, nutritional factors, and ischemia all having a role in its pathogenesis. Although predilection sites are variable among species, the morphology of the early lesio...
Guyton K, Houchen-Wise E, Peck E, Mayberry J.Horse-related injury can be severe and disabling. We investigated the causes, severity, and costs of equestrian injury with the goal of injury prevention. A retrospective review of horse-related injuries from 2001 to 2008 identified 231 patients with a mean age of 38 years and a mean Injury Severity Score of 11 (range, 1 to 45). Mean length of stay was 5.5 days. Fifty-nine patients (25%) required 84 surgeries. Helmet use was 20 per cent and of the 172 patients not wearing a helmet while mounted, 38 per cent received potentially preventable head injuries. There were three deaths of which two we...
Lloyd RG.All horse-related injuries presenting to an Accident Service over a two-year period were investigated. 237 patients presented. The injuries were not considerable in absolute number but were in severity. There was a high morbidity with 22% of all patients requiring admission to hospital, 50% of all admissions because of head injuries. At least seven life-threatening injuries were identified and there were other severe pelvic and spinal injuries. The wearing of protective head gear remains the most important safety measure.
Rueda MA, Halley WL, Gilchrist MD.This article presents and analyses injury incidence rates for amateur and professional racing jockeys in Ireland, France and Britain by means of a retrospective study and review of published data. Amateur jump racing was seen to have the highest fall risk in these three countries (between 115 and 140 falls/1000 rides). Jump racing also had the highest rates of injury/ride amongst both amateur and professional jockeys. Flat racing, however, had the highest rates of injuries/fall (34-44%). Of all the injuries in both jump and flat racing populations of amateur and professional jockeys, 15% were ...
Dyson SJ, Murray R, Schramme MC.The diagnosis of foot-related lameness often remains elusive and it can be difficult to offer rational treatment, or to predict outcome. Objective: To describe the spectrum of injuries of the foot identified using magnetic resonance imaging (MRI), to determine their relative prevalence among MRI diagnoses and to establish the long-term results of treatment. Methods: The MR images of horses examined from January 2001--December 2003 were reviewed. Horses were selected for MRI if the pain causing lameness was localised to the foot using perineural analgesia but any clinical, radiological or ultra...
Barr ED, Pinchbeck GL, Clegg PD, Boyde A, Riggs CM.Thoroughbred racehorses are commonly affected by subchondral bone injury, but the exact prevalence and the distribution of palmar/plantar osteochondral disease (POD) lesions are unknown. The relationship between pathologies has not been elucidated, although it is widely accepted that POD is a manifestation of traumatic overload arthrosis. Objective: There is an association between grade of POD and other pathologies affecting the third metacarpal and metatarsal (MC/MTIII) condyles (wear lines, cartilage loss, marginal remodelling, dorsal impact injuries and linear fissures). Objective: To evalu...
Bond GR, Christoph RA, Rodgers BM.To assess the impact of helmet use on the pattern, and severity of pediatric equestrian injuries. Methods: A prospective observational study of all children less than 15 years of age who were brought to the University of Virginia children's Emergency Department with horse-related injuries. Results: During the two-year period of the study, 32 children were evaluated. Two children were injured when a horse stepped on them. Thirty children fell from or were thrown from a horse. Of these, 20 were wearing a helmet. Head injuries were more frequent in those patients not wearing helmets. The mean Mod...
Jagodzinski T, DeMuri GP.Horseback riding is an increasingly popular activity among today's youth, providing them with the opportunity to learn responsibility and respect for animals. However, it can also be associated with severe injury, of which many physicians are unaware. In 2002, there were an estimated 13,400 emergency department visits nationwide for horse-related injuries among children younger than 15 years. When using a severity score to compare it with other childhood injuries, equestrian-related injury ranked second only to pedestrians being struck by a car, and had a higher score than all terrain vehicle,...
Havlik HS.Equestrian sports continue to grow in popularity in the Unites States and abroad, with an estimated 30 million people riding horses annually in the United States alone. Approximately one in five of these riders will suffer a serious injury during their riding career, requiring medical care and potentially hospitalization. Riding carries with it an implicit risk of injury associated with the unpredictability of the animals, the rider's head being positioned approximately 9 feet off the ground, and traveling unrestrained at speeds up to 40 mph. This article reviews common equestrian injuries, ep...
van Loon JPAM, Van Dierendonck MC.Objective pain assessment is important to guide and tailor therapy in clinical practice. This study describes the clinical applicability and validity of two pain scales, the Composite Pain Scale (CPS) and the Equine Utrecht University Scale for Facial Assessment of Pain (EQUUS-FAP) in horses with orthopaedic trauma or after orthopaedic surgery. A cohort follow-up study was performed using 77 adult horses (n=43 with orthopaedic trauma or injury; n=34 controls). Composite and facial expression-based pain scores were assessed by direct observations of pairs of two independent observers. All horse...
Waller AE, Daniels JL, Weaver NL, Robinson P.In the sport of horse racing, the position of the jockey and speed of the horse predispose the jockey to risk of injury. Objective: To estimate rates of medically treated injuries among professional jockeys and identify patterns of injury events. Methods: Cross-sectional survey from data compiled by an insurance broker. Information on the cause of injury, location on the track, and body part injured was evaluated. Methods: Official races at US professional racing facilities (n = 114) from January 1, 1993, through December 31, 1996. Methods: A licensed jockey population of approximately 2700 pe...
Huser CA, Peacock M, Davies ME.Chondrocyte death, a notable feature of osteoarthritis, may play a role in the initiation of cartilage degeneration. The present study was aimed at uncovering the nature and involvement of cell death in the initiation of cartilage degeneration induced by mechanical trauma. Methods: Articular cartilage discs obtained from healthy skeletally mature horses were subjected to a single-impact load (500 g from 50 mm) using a simple drop-tower device and cultured in vitro for 48 h. Chondrocyte death was examined using two independent methods: transmission electron microscopy and caspase-3 activity ass...
