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.
Dwyer AE.Equine practitioners examine patient eyes on a daily basis. Indications range from inspection of normal anatomy to treatment of traumatized eyes to workups of sight threatening inflammatory or neoplastic ocular conditions. Assessment of equine eyes requires practitioners to take time to create a good "exam room" in the field and administer appropriate restraint, sedation and/or regional anesthesia to facilitate thorough examination. Accurate diagnosis and treatment of equine eye problems requires skill in ocular surface staining and cytology, and basic proficiency in standing surgery. Expertis...

Lacourt M, Gao C, Li A, Girard C, Beauchamp G, Henderson JE, Laverty S.To correlate degenerative changes in cartilage and subchondral bone in the third carpal bone (C3) of Standardbred racehorses with naturally occurring repetitive trauma-induced osteoarthritis. Methods: Fifteen C3, collected from Standardbred horses postmortem, were assessed for cartilage lesions by visual inspection and divided into Control (CO), Early Osteoarthritis (EOA) and Advanced Osteoarthritis (AOA) groups. Two osteochondral cores were harvested from corresponding dorsal sites on each bone and scanned with a micro-computed tomography (CT) instrument. 2D images were assembled into 3D reco...
Caston SS.Care of equine wounds in the field can be a challenging endeavor. Many times, wound care is complicated by chronicity or by prior inappropriate care in addition to the great degree of tissue trauma that occurred when the horse was wounded. Recognizing involvement of synovial structures, loss of skin, and damage to bone are critical in the initial examination of wounds and will guide future care. Education of clients is also important in that preparing them for possible outcomes during healing may help improve compliance and proper treatment of wound. Owners and trainers often perform much of t...
Cesarini C, Macieira S, Girard C, Drolet R, d'Anjou MA, Jean D.The costochondral junction constitutes a potential site of infection in septic foals and it could be favored by thoracic trauma. Standard radiographs and ultrasonography are useful tools for diagnosis of this condition and ultrasound-guided needle aspiration could permit the definitive confirmation of infection. La jonction costochondrale constitue un site potentiel d’infection chez le poulain septicémique et le développement de l’infection pourrait être favorisée par un traumatisme costal. Les radiographies standards et l’échographie sont des aides diagnostiques et l’aspiration ...

In a retrospective study design, 264 show-jumping riders (105 professionals, 159 amateurs) were interviewed by means of a standardised questionnaire. In total, 636 injuries were reported in detail. Injuries were categorised into severity grade I (36.0 %) (not requiring medical attention), grade II (34.6 %) (single medical treatment), grade III (20.9 %) (several outpatient medical treatments) and grade IV (8.5 %) (req...
Tokateloff N, Carmalt J, Manning S.A horse was initially diagnosed with hemarthrosis and desmitis of the long medial collateral ligament of the right tarsus and later developed prominent enthesiophytosis at the site of insertion of the ligament's deep portion. Hemarthrosis due to intra- or peri-articular pathology can cause recurrent lameness, even without evident external trauma. Un cheval a été initialement diagnostiqué avec de l’hémarthrose et une desmite du ligament deltoïdien latéral long du tarse droit et a ultérieurement développé de l’enthésiophytose proéminente au site de l’insertion de la portion pro...
Bleetman D.The Great Western Ambulance Service Air Support Unit (ASU) was established in July 2007. The helicopter carries a doctor, providing a Helicopter Emergency Medical Service (HEMS) model of care. Equestrian sport-related injuries account for 6.8% of the unit's total attended case load. Horse riding has a higher rate of severe injury than motorcycle racing and 45% of patients admitted with equestrian injuries require surgical intervention. Orthopaedic injuries to the extremities are commonest, superseding head injuries since the introduction of protective headwear. The majority of equestrian sport...
del Junco CI, Mair TS, Powell SE, Milner PI, Font AF, Schwarz T, Weaver MP.The magnetic resonance (MR) imaging features, signalment, clinical history and outcome of 55 horses with a penetrating sole injury were evaluated. Our aim was to describe MR imaging findings within the hoof capsule, assess the utility of the technique and give recommendations for the optimal MR imaging protocol to evaluate such injuries. Data from five equine hospitals were analyzed retrospectively. The tract was more likely to be visualized in animals scanned within the first week postinjury. There was no significant predisposition based on breed, age, or gender. T2*W transverse sequences wer...
Dyson S, Nagy A, Murray R.Eight sports horses with unilateral (4) or bilateral (3) forelimb or unilateral hindlimb (1) lameness had subtle radiologic abnormalities of the subchondral bone of the sagittal groove of the proximal phalanx associated with moderate or intense increased radiopharmaceutical uptake. High-field or low-field magnetic resonance (MR) imaging confirmed the presence of a fissure fracture or subchondral and trabecular bone trauma. Seven of eight lesions were located approximately midway between the dorsal and palmar cortices of the proximal phalanx; the eighth was sited more dorsally. Two horses under...
Koren L, Stahl S, Rovitsky A, Peled E.Amputation of fingers with tendon avulsion occurs through a traction injury, and most occur through a ring avulsion mechanism. Usually the flexor digitorum profundus is torn out with the amputated finger. Replantation usually is recommended only when the amputation is distal to the flexor digitorum superficialis insertion. Animal bites are relatively common, with a decreasing order of frequency of dogs, cats, and humans. Horse bites are relatively infrequent but are associated with crush injuries and tissue loss when they occur. This article describes a 23-year-old man with amputation of his m...
Owen KR, Singer ER, Clegg PD, Ireland JL, Pinchbeck GL.Traumatic injuries are a major cause of morbidity and mortality in the horse and consequently pose a serious threat to horses' wellbeing.

Nell B, Walde I.Diseases of the vitreous, fundus and optic nerve are described and illustrated according to their ophthalmological appearance. Vitreal alterations are commonly of developmental, degenerative, age related, traumatic or inflammatory origin and of minor clinical relevance. In contrast, those affecting the fundus, may be accompanied by visual deficits or blindness. Fundic lesions of inflammatory (multifocal or peripapillary chorioretinitis, haemorrhage, retinal detachment) and traumatic origin have to be differentiated from congenital (congenital stationary night blindness, colobomatous defects, r...
Keilani ZM, Berne JD, Agko M.Blunt cerebrovascular injuries, defined as blunt injuries to the internal carotid or vertebral arteries, are uncommon and usually occur in victims of high-speed deceleration motor vehicle crashes. A blunt cerebrovascular injury after an equestrian accident is an extremely unusual presentation. In recent years, advances in screening and treatment with pharmacologic anticoagulation before the onset of neurologic symptoms have improved outcomes for these patients. Endovascular stenting and embolization, although unproven, offer a new potential approach for these complex injuries. We present a uni...
Hessler C, Schilling B, Meenen NM, Lockemann U, Püschel K.Equitation is associated with a high rate of injuries and lethal accidents. The head is the most frequently concerned body part. Hence in the majority of the cases deaths results from head injuries. In this study injuries as well as causes of deaths were analyzed in 21 cases. Actual safety standards in equitation were appraised and suggestions for improvement were formulated. Methods: Between 1996 and 2008 21 equestrians suffered from a fatal accident in the greater area of Hamburg. In a retrospective analysis, equestrians' records which bases on the documentation of the institute of forensic ...
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...
Ebert LC, Schön CA, Ruder TD, Thali MJ, Hatch GM.Horse kicks are rare incidents-especially, if they end in fatality. In this case, a 13-year-old girl collapsed 3 minutes after sustaining a kick to the chest from a pony. Resuscitation attempts were unsuccessful. Postmortem computed tomography and magnetic resonance imaging were performed before autopsy.Imaging revealed a 3-cm long laceration of the left ventricle and a large pericardial effusion. Using segmentation techniques, the amount of blood inside the pericardium was determined. These findings correlated well with the autopsy findings. Pericardial tamponade was determined at autopsy to ...
Forero Rueda MA, Cui L, Gilchrist MD.Jockey head injuries, especially concussions, are common in horse racing. Current helmets do help to reduce the severity and incidences of head injury, but the high concussion incidence rates suggest that there may be scope to improve the performance of equestrian helmets. Finite element simulations in ABAQUS/Explicit were used to model a realistic helmet model during standard helmeted rigid headform impacts and helmeted head model University College Dublin Brain Trauma Model (UCDBTM) impacts. Current helmet standards for impact determine helmet performance based solely on linear acceleration....
Antoun JS, Steenberg LJ, Lee KH.Facial injuries caused by horses are relatively common among riding enthusiasts, but little is known about the nature of maxillofacial fractures sustained by those not mounted. We collected data on patients' characteristics, fractures sites, mechanisms of injury, and treatment of these fractures from the departmental records of the oral and maxillofacial unit at Christchurch Hospital, New Zealand between 1996 and 2008. Of 49 patients with equine-related facial fractures, 35 (mean (SD) age 35.8 (16.7) years) had sustained their injuries while unmounted (71%). Most of the fractures occurred in w...

Results: Resolution of carpal sheath effus...
Pownder S, Scrivani PV, Bezuidenhout A, Divers TJ, Ducharme NG.In people, specific classifications of temporal bone fractures are associated with clinical signs and prognosis. In horses, similar classifications have not been evaluated and might be useful establishing prognosis or understanding pathogenesis of certain types of trauma. Objective: We hypothesized associations between temporal bone fracture location and orientation in horses detected during computed tomography (CT) and frequency of facial nerve (CN7) deficit, vestibulocochlear nerve (CN8) deficit, or temporohyoid osteoarthropathy (THO). Complex temporal region anatomy may confound fracture id...
Voermans M, Skidell J, Winberg F.Prestenotic oesophageal dilatation and stricture were diagnosed in a horse with a history of trauma in the cervical area and recurrent oesophageal obstruction. The diagnosis was established on the basis of the clinical examination, endoscopy, and positive contrast oesophagography. Conservative treatment was unsuccessful and surgical intervention was necessary. Oesophageal myectomy combined with myoplasty was performed, simultaneously relieving the dilatation and the stricture. No abnormalities were detected 8 weeks after surgery. The horse was on a normal diet and oesophageal obstruction did r...
Haig L, Skinner K.Equine-assisted services (EAS) are gaining popularity as ways to promote psychological health and social well-being. EAS may show particular promise as culturally appropriate initiatives for at-risk Indigenous youth, as they are thought to align well with Indigenous ways of knowing which place emphasis on relationships between the land and all living beings. We seek to better understand previous uses of EAS as initiatives for at-risk youth populations, including Indigenous populations, and learn about which outcomes have been addressed in the literature with an EAS initiative by conducting a s...
Nelson C, Dossett K, Walker DL.Equine-assisted therapy has emerged as an adjunctive integrative health modality in treating individuals experiencing physiological and psychological distress. However, limited research exists to assess the efficacy of such treatments as a possible adjunct to psychological treatment for Posttraumatic Stress Disorder (PTSD) in first responders. The current pilot study examines the additive benefits of equine-assisted exposure for first responders suffering occupational incapacitation from operational-related trauma. Seven first responders participated in an 8-week, 90-minute, equine-assisted th...

Information on crashes occurring on public roads during the years 2010-2013 was obtained from the Pennsylvania Department of Transportation (PennDOT) and analyzed. There were 344 farm equipment and 246 horse and buggy crashes during the 4-year study period. These crashes involved 666 and 504 vehicles and 780 and 838 people, respectively. In incide...
Balakrishnan A, Abbadi R, Oakland K, Jamdar S, Harper SJ, Jamieson NV, Huguet EL, Jah A, Praseedom RK.Equestrian sports are common outdoor activities that may carry a risk of liver injury. Due to the relative infrequency of equestrian accidents the injury patterns and outcomes associated with liver trauma in these patients have not been well characterized. Methods: We examined our experience of the management of equestrian liver trauma in our regional hepatopancreaticobiliary unit at a tertiary referral center. The medical records of patients who sustained liver trauma secondary to equestrian activities were analysed for parameters such as demographic data, liver function tests, patterns of in...
Arnold CE, Chaffin MK, Rush BR.Cystic hematomas were diagnosed in 3 neonatal foals. In all 3 foals, cystic hematomas resulted from umbilical trauma or thrombocytopenia. Findings in these foals suggest that cystic hematoma should be included in the differential diagnosis of hematuria in neonatal foals. Management of cystic hematomas includes both medical and surgical options.
Islam S, Walton GM, Dean F, Hoffman GR.This case report describes an unusual and complicated orbital injury inflicted by a horse. Definitive management required multidisciplinary surgical collaboration to prevent significant ocular sequelae. The diagnostic role of good imaging and the potential use of bio-models are highlighted.
Moore CP, Halenda RM, Grevan VL, Collins BK.Traumatic keratouveitis in horses is characterised by a unilateral, aseptic, vascularising keratitis accompanied by moderate to severe anterior uveitis. In a series of 9 cases of post traumatic keratouveitis, topical and systemic nonsteroidal drugs and atropine were used to control the anterior uveitis while allowing spontaneous corneal healing. Among the 9 cases reported, 6 affected eyes previously treated with local corticosteroids took significantly longer to resolve when compared to 3 eyes in which corticosteroids had not been administered. It was concluded that, in cases of equine post tr...
Mazaheri-Khameneh R, Azizi S, Davoodi F, Gooran MM.One of the traumatic fractures occurring in the hindlimb of the foals is physeal fractures of the tibia. The most common type of proximal tibial fracture in foals is reported to be Salter-Harris type II. Methods: This case report describes the history, clinical signs, radiographic findings, and surgical management of a proximal physeal fracture of the tibia due to the kick trauma in a 2-weeks-old Kurdish female foal, with signs of left pelvic limb lameness, valgus deviation with non-weight-bearing, non-mobility in stifle region and crepitation in the affected area. In this case, radiography wa...
Nixon AJ, Stashak TS.Malalignment of the atlas and axis was seen in 4 horses with an idiopathic form of atlantoaxial subluxation characterized by spinal cord compression on extension. The bone structure and density of the atlas and axis were radiographically normal in 3 of the 4 horses. Clinical signs appeared when the horses were 6 to 30 months old, and 3 of the 4 horses had a history of trauma. Although a congenital anomaly could not be ruled out, the cause was thought to be trauma. The horses were moderately to severely ataxic at the time of examination. Myelography revealed compression of the spinal cord at th...
Bertone JJ, Dill SG.An ingested metallic foreign body migrated from the stomach and induced restrictive pericarditis in a horse. Necropsy revealed chronic abdominal and acute thoracic lesions. Although rare, ingested foreign body migration should be considered in the differential diagnosis of body cavity disease in horses.
Summerhays GE.Eight horses with synovial sepsis induced by trauma were treated by arthroscopic/tenoscopic debridement and lavage followed by the implantation of a gentamicin-impregnated collagen sponge. Seven of them responded favourably and were sound six months after treatment. The other underwent a further surgical procedure and recovered. Gentamicin-impregnated collagen sponges appear to be a safe and useful adjunct in the treatment of septic joints and tendon sheaths, and have the advantage of being bioabsorbable.
Rendle DI, Hughes KJ.Intracameral injection of tissue plasminogen activator has been suggested as a means of hastening the clearance of blood from the anterior chamber and reducing the risk of synechia and fibrotic membrane formation in horses with hyphaema. The following report describes a case of ocular trauma in which intracameral injection of tenecteplase (TNK), a new-generation plasminogen activator, resulted in rapid resolution of hyphaema and successful outcome. However, a large dose (1 mg) was administered and may have been associated with retinopathy and keratopathy. TNK may be an effective treatment for ...
Franzén Lindgren E, Hammarqvist F, Ahl Hulme R.Horse-riding is practiced on a regular basis by 500,000 people in Sweden. It is reputed to be one of the most dangerous sports. On average, there were 1756 acute injuries and three fatalities each year between 1997 and 2014 in Sweden related to horses. The primary aim of this study was to outline the injury spectrum related to equestrian activities cared for at a large Swedish trauma centre. The secondary aim was to identify trends in clinical outcomes and to investigate the association between age and such outcomes. Methods: The electronic medical records system at Karolinska University Hosp...
Estell K.Acute central nervous system (CNS) trauma in the field is best approached by a systematic and thorough physical and neurologic examination that allows the practitioner to localize the brain or spinal cord injury. The skull and vertebral canal are complex 3-dimensional structures, and orthogonal radiographic views are necessary for an accurate diagnosis. Therapeutics aimed at decreasing pain, inflammation, and edema or increased intracranial pressure in the case of traumatic brain injury should be administered. Survival and return to athleticism can be achieved even in moderate-to-severe trauma...

Martin L, Kaswan R, Chapman W.Traumatic optic nerve atrophy is characterised clinically by a unilateral or bilateral sudden onset of blindness. Dilated, fixed pupils and a lack of a menace reflex are the only abnormalities noted soon after the trauma. Within three to four weeks the optic disc becomes paler and the retinal vasculature is markedly decreased. The pathological lesion is a rupture of the nerve axons from stretching forces produced by the posterior movement of the brain against the fixed canalicular portion of the optic nerves. Medical therapy has not been successful.
Hurcombe SDA, Radcliffe RM, Cook VL, Divers TJ.Hemorrhagic shock in horses may be classified in several ways. Hemorrhage may be considered internal versus external, controlled or uncontrolled, or described based on the severity of hypovolemic shock the patient is experiencing. Regardless of the cause, as the severity of hemorrhage worsens, homeostatic responses are stimulated to ameliorate the systemic and local effects of an oxygen debt. In mild to moderate cases of hemorrhage (<15% blood volume loss), physiological adaptations in the patient may not be clinically apparent. As hemorrhage worsens, often in the uncontrolled situation suc...
King JM, Roth L, Haschek WM.Focal myocardial necrosis secondary to neural lesions was diagnosed in 2 dogs and 1 horse. In each case, the neural lesions were traumatic in origin. Spinal cord injury was evident in 1 dog; brain damage was evident in the other dog and presumably in the horse. Retrospective analysis of necropsy material showed that many species were affected, without apparent age or sex predisposition. Central nervous system injury resulting from trauma, infection or space-occupying lesions was associated with acute myocardial necrosis in all cases. The myocardial necrosis was rarely fatal; however, it did ca...
Puangthong C, Bootcha R, Petchdee S, Chanda M.A 17-year-old mixed breed pony was presented with intermittent neck stiffness during regular training rides in the six months preceding its admission. All parameters were within the normal range, except for an increase in heart rate (48 bpm) during the examination. Concave areas were observed at the level between the atlas and axis vertebrae (C1-C2) on both the left and right sides of the neck. Radiographs were taken of the laterolateral, left ventrodorsal oblique, and right ventrodorsal oblique projections in the cranial cervical region. The images revealed severe structural disorders, includ...
