Injury in horses encompasses a range of physical traumas that can affect various tissues and structures, including bones, muscles, tendons, and ligaments. These injuries can arise from numerous causes, such as accidents, overexertion, or improper handling. Common types of equine injuries include fractures, sprains, strains, and lacerations. The management and treatment of these injuries require an understanding of equine anatomy and biomechanics, as well as appropriate veterinary care. This page collects peer-reviewed research studies and scholarly articles that explore the causes, diagnosis, treatment, and prevention of injuries in horses, providing insights into their impact on equine health and performance.
Haughey KG, Jones RT.A high frequency of meningeal lesions was found at autopsy in foals dying perinatally. Such lesions are considered an index of injury to the fetal central nervous system, from trauma and/or hypoxia during birth. Their incidence in the sample examined (26 foals) is similar to that observed in the perinatal mortality of lambs and calves.
d'Abreu F.This research article discusses brain injuries in jockeys, particularly in horse racing. The author recounts the preventive measures taken by the Jockey Club and the Betting Levy Board to protect […]
Gierup J, Larsson M, Lennquist S.A prospective one-year study of horse-riding accidents was performed in an area with a very high frequency of amateur riding. Totally 174 patients with riding injuries were registered--66% children--making an incidence of only 0.7 per thousand riding occasions. However, many of these injuries were of a severe nature, one leading to death and 27 of the patients reporting persisting symptoms at follow-up one year after the accident. Eleven per cent of the accidents lead to cerebral injuries and 44% to fractures, mainly of the upper extremities. Eleven per cent required hospitalization and 17% op...
Pickett BW, Voss JL.Experimental and clinical observations were made to treat abnormal sexual behaviour. The most common cause of abnormality was mismanagement of the animal; over-use and rough treatment at service and too-frequent ejaculation during winter had a detrimental effect on the behaviour of young stallions. Pain due to injury incurred at copulation or when associated with mounting attempts was also a common cause of impotence. Most impotent stallions responded well to re-training and recovery can be achieved without pharmacological treatment in most cases.
Norrie RD.The concept of regenerative healing has been used to manipulate the healing process in experimental animals and clinically to augment bone healing in people after orthopedic operation. An implanted electrical device was used in an attempt to produce regenerative healing in experimentally created equine tendon injury. The bimetallic electrical implant did not produce regenerative healing under the conditions of this experiment. The mechanism of implantation and discussion of the results are included.
Turner AS, Gabel AA.Avulsion fractures of the posteromedial eminence of the 2nd phalanx were repaired, using an ASIF cortex screw in 3 reining Quarter Horses. Within 9 and 11 months, respectively, 2 horses were sound and back in competition as reining horses. The other horse was sound for pleasure class showing at 7 months after surgery.
Pauli B, Althaus S, Von Tscharner C.Migrating fourth-stage larvae of Strongylus vulgaris, a parasite of equines, damage the intima of the anterior mesenteric artery and its larger branches and induce thrombus formation on the injured sites. As the time of larval passage through each of these branches has been exactly determined in earlier experiments, the aim of the present studies is to contribute to a more complete understanding of repair mechanisms in the process of time after thrombotic vascular injuries. Methods: five foals were separated individually to specially cleaned stables and given anthelmintic treatment till the ag...
Gelatt KN.Traumatic iridocyclitis and hyphema in the horse usually follow blunt blows to the orbit and eye. The condition is characterized by miosis, ocular hypotony, ciliary flush, swelling of the iris, and hemorrhage with excessive fibrin in the anterior chamber which permits from 2 to 6 weeks. Vigorous treatment with mydriatics, topical and systemic corticosteroids is recommended. Possible complications include anterior and posterior synechiae, cataracts, and fibropupillary membranes.
Johnson JE, Ryan GD.Soft tissue lesions are often secondary to equine carpal injury. The clinical and pathological nature of soft tissue changes following carpal trauma are varied. This report describes a case of intersynovial fistula between the radial carpal joint and the common digital extensor tendon sheath. The differential diagnosis and pathological features of equine soft tissue carpal injuries are discussed.
Strömberg B.Thermography in veterinary medicine has hitherto been proven to be a method of great value in the detection of orthopaedic lesions in racehorses. Lesions of the musculo-skeletal system affecting tendons, joints, bones and skeletal muscle can be demonstrated and documented at an early stage thereby preventing the development of more serious lesions.
Evans JH, Barbenel JC.Tendon normally fulfills its primary role as a flexible force transmitting element very effectively and yet failure of this passive tissue leads to great disability. As a connective tissue its structure is relatively simple and the peculiar helical arrangement of collagen fibres confers highly non-linear as well as time-dependent mechanical properties. Functional significance cannot be attributed to any facet of mechanical response until the physiological pattern of loading is established. In particular the rate of deformation and the minimum force experienced by tendon in normal locomotion ha...
Hudson S, Blackburn J, Fish M, Ousey K.Police officers wear personal protective equipment (PPE) to reduce their risk of injury while on duty. Despite the unique policing activity of riding a horse, little is known about the PPE used by mounted officers. The aim of this research was to assess the use, comfort, and functionality of mounted police PPE. Twenty officers from three UK Mounted Sections were recruited. Semi-structured interviews and range of movement assessments were conducted. Interview data was analysed using reflexive thematic analysis. Three main themes were generated: and Much of the PPE worn by mounted officers is ...
Isgren CM, Pinchbeck GL, Salem SE, Hann MJ, Townsend NB, Cullen MD, Archer DC.Surgical site infection (SSI) is a frequent complication following emergency equine laparotomy, negatively impacting equine welfare, increasing treatment costs and presenting a hospital biosecurity risk. Objective: To determine if a sutured-on stent dressing for incisional protection during anaesthetic recovery reduced SSI following emergency laparotomy. Methods: Randomised controlled trial. Methods: Eligible horses were randomised to a sutured-on stent (intervention) or textile dressing (control) as the primary component of a 3-layer abdominal bandage placed for anaesthetic recovery. Horses w...
Parente A, Geburek F, Kästner S, Iversen C, Hopster K.Orotracheal intubation is commonly performed for inhalation anaesthesia in horses to ensure safe and reliable administration of volatile anaesthetics and to secure the airways. In human and equine medicine, the occurrence of intubation-associated complications has been described, which can range from mild mucosal irritation to severe necrosis. However, there are only sparse descriptions of mucosal alterations and the course of healing after elective surgery in horses. Objective: To investigate the prevalence and severity of tracheal lesions following endotracheal intubation associated with gen...
Poizat E, Gérard M, Macaire C, De Azevedo E, Denoix JM, Coudry V, Jacquet S, Bertoni L, Tallaj A, Audigié F, Hatrisse C, Hébert C, Martin P....Lameness detection in horses is a critical challenge in equine veterinary practice, particularly when symptoms are mild. This study aimed to develop a predictive system using a support vector machine (SVM) to identify the affected limb in horses trotting in a straight line. The system analyzed data from inertial measurement units (IMUs) placed on the horse's head, withers, and pelvis, using variables such as vertical displacement and retraction angles. A total of 287 horses were included, with 256 showing single-limb lameness and 31 classified as sound. The model achieved an overall accuracy o...
Vandaele Z, Van den Broeke C, Merchiers A, Schauvliege S.Different assisted recovery techniques have been developed to enhance the safety and quality of equine recoveries. This case series evaluates the recovery of horses using an air-inflated pillow (Equi-lift®). With owner consent, the following data were collected from 19 horses undergoing open castration and 21 horses where a difficult recovery was anticipated: age, bodyweight, procedure, anaesthetic protocol, time required for proper positioning in the Equi-lift®, time to extubation, time to standing, number of attempts to stand, number of stimuli, behaviour during recumbency/first attempts, ...
Campebell RC, Oliveira AB, Fagundes JLA, Fortes BNA, Veado HC, Macedo IL, Dallago BSL, Barud HS, Adorno J, Salvador PAV, Santos PS, Castro MB.This study evaluates the wound-healing process in horses following the application of two treatment modalities: bacterial cellulose hydrogel with alginate (BCAW) and frog skin (FSW) dressings on experimentally induced skin wounds. Throughout the experiment, no clinical abnormalities were noted in the horses, although initial wound assessments indicated edema and sensitivity. Local hemorrhage was observed in some cases on Day 0, with granulation tissue formation evident by Day 14. Epithelialization began around Day 14 but did not reach complete healing in any group by Day 28. The analysis showe...

Standing bandages were then applied to both front limbs for 60 mi...
Schiele AR, Valletti C, Ringer SK.A Trotter mare (aged 5 years 8 months) presented with severe thoracic limb lameness 2 years after screw fixation of a third carpal bone fracture. Septic arthritis of the intermediate carpal joint necessitated three anaesthetics: two arthroscopic lavages in dorsal recumbency, followed by a computed tomography-guided screw explantation with curettage of an infected, sclerotic third carpal bone in right lateral recumbency. For each anaesthetic, maintenance was with isoflurane carried in oxygen and air, and a medetomidine constant rate infusion. Twelve days after the third anaesthetic, the horse h...
Woods TDC, Dixon J, Fraser BSL, Melvaine C.Exploratory tenoscopy is considered the gold standard technique to identify intrathecal pathology of the equine carpal flexor tendon sheath (CFTS). Preoperative diagnosis allows for more precise prognostication and surgical planning, potentially associated with improved surgical outcomes. This prospective, descriptive, anatomical study aimed to describe the anatomy of the equine CFTS using noncontrast and contrast CT in clinically normal cadaver limbs. Ten pairs of equine forelimbs free of gross external abnormalities were examined from mid-antebrachium to distal metacarpus. Specimens initiall...
May A, Riley CB, Scharre A, Zablotski Y, Padalino B.Equine road transport is stressful and associated with an increased risk of behavioral problems, injuries, respiratory and gastrointestinal diseases. This cross-sectional survey-based study aimed to describe transport-related practices and the perception of behavioral and health issues in Germany. The survey targeted horse owners (amateurs and professionals) and obtained demographic details, the participant's experience, frequency and duration of transportation, and behavioral and health problems related to equine transportation. Associations among behavioral and health problems and transport ...

Objective: To identify horse-, race- and track-level risk factors associated with race-related fatal musculoskeletal injury (MSI) of Thoroughbred racehorses in North America. Methods: Retrospective cohort study. Methods: The study cohort included all race starts made by horses born after 31 December 2006, at tracks that fully report to the EID and consisted of 3,851,659 race s...
Quinn CT.Catheterisation of the urinary bladder is a common procedure during perioperative care of horses. Benefits of urinary catheters include a reduction in the risk of recovery-associated slip hazards as a consequence of voided urine and the measurement of urine output during anaesthesia. However, there is little information regarding the risks associated with this procedure. A retrospective cohort study was undertaken in horses admitted to a university teaching hospital for surgery during which a urinary catheter was placed perioperatively. Data were retrieved from clinical records including signa...
Loppnow Z, Kersh K, Wang C, Spaethe S, Troy J.The clinical outcomes in horses diagnosed with established synovial sepsis (SS) or minimally contaminated synovial wounds (SW)/non-established sepsis, following intravenous regional limb perfusion (IVRLP) treatment, have not been reported since 2010. Additionally, previous reports on this subject were confined to just two clinical retrospective reports. This study aimed to provide an update on the short-term (hospital discharge) and long-term (≥1 year) survival rates in adult horses diagnosed with SS or SW treated with IVRLP at a single institution in the USA from 2010-2020. The study also...
Cameron-Whytock HA, O'Brien D, Lewis V, Parkin T, Bennet ED.To date, industry and research outputs that have aimed to improve safety in equestrian eventing have tended to focus on identifying risk factors for horse falls during cross-country, which have been identified as the greatest risk of injury and fatality for riders. There is an absence of research that investigates fatalities of horses within the sport of eventing. Objective: To use a combination of media reports and eventing federation databases to describe and document equine fatalities in equestrian eventing, including their context, location and a basic pathology. Methods: Descriptive study...
Kirkpatrick CJ, Ernst NS, Trumble TN.Injury to the collateral ligament (CL) of the distal interphalangeal joint (DIPJ) is recognized as a source of lameness in horses. Intralesional injection has been advocated to increase return to performance. This study was a proof-of-concept study in standing horses to evaluate success of a palmar radiographic-guided approach for injecting insertions of the DIPJ CLs previously described in cadaver limbs. Horses were sedated, nerve blocked, and placed on wooden blocks with the limb to be injected staggered approximately 20cm cranially to the other limb. The DIPJ CL insertion was injected, usin...
Kerbert MP, Delling U, Verhaar N.To investigate the computed tomography (CT) and gross anatomy of the equine medial digital flexor tendon sheath (MDFTS), and the endoscopic anatomy and approach to the MDFTS. Methods: Ex vivo experimental study and one clinical case. Methods: Twelve clinically normal cadaveric hindlimbs. Methods: Dissection, native and contrast CT scans were conducted to evaluate the anatomy of the MDFTS. Based on these findings, the portal locations for the endoscopic approaches were determined. Six hindlimbs were used in the pilot phase and another six limbs were selected for the main study. Endoscopic image...
Albanese V, Straticò P, Fischer H, Petrizzi L.Injuries to the distal limb are common in horses. The clinical aspect of the lesions is variable based on the structures that are involved. Synovial structures as well as tendons and/or ligaments may be involved in such injuries, affecting treatment modalities and costs, and prognosis. This retrospective study compares wounds involving synovial structures to wounds without such involvement in terms of treatment duration and costs, and prognosis. Synovial wounds were much more expensive to treat and carried a lower prognosis. Involvement of tendons and/or ligaments in the wounds resulted in mor...
Shokry M, Ali LB, El-Sharkawy M.Showjumping athletic horses are frequently affected by back pain, which in turn influences their performance and equestrian activities. Unassigned: The aim of the present study was to determine the etiological factors predisposing to back problems in show jumping horses and how to diagnose, and manage them. Unassigned: A total of 75 cases (45 geldings and 30 mares, aged between 8 and 23 years and weighing 420-550 Kg) with histories suggestive of back problems and low competitive ability as show jumping were used in this study. The evaluation of data was based on the inputs of case history, cli...
Tulloch JSP, Schofield I, Jackson R, Whiting M.The veterinary industry has some of the highest rates of non-fatal work-related injuries, yet safety culture remains unexplored. Utilising a survey distributed to all UK employees of a consolidated group of veterinary practices, this study aimed to describe the prevalence of work-related injuries in equine, production animal, and mixed veterinary practices, and to understand the behaviours of injured persons. There were 144 respondents. Over 90 % of clinicians experienced injury during their careers, versus a third of non-clinical staff. Injuries to equine veterinarians were predominately ki...
Sohn Y, An SJ, Forbes E, Kim BS, Jeon HS, Ryu SH, Lee I.The lateral trochlear ridge of the stifle joint is highly susceptible to developing Osteochondrosis (OC)/Osteochondritis dissecans (OCD) lesions. This retrospective study evaluated the medical and racing outcomes of 75 Thoroughbreds who underwent arthroscopic OCD removal at the Jeju Stud Farm Equine Hospital from 2015 to 2017. The analysis included medical records, radiographic assessments, and race performance data, comparing 75 horses that underwent surgery with 257 control horses selected as siblings from the same dam. The surgical group had comparable racehorse registration rates (89.3 %...
Scharf A, Acutt E, Bills K, Werpy N.Deep digital flexor (DDF) tendinopathy is a significant cause of lameness and poor performance in equine athletes with substantial implications for their return to athletic performance. Magnetic resonance imaging (MRI) is increasingly integrated into the diagnostic workup of horses with foot pain and has revolutionised the diagnosis and management of these injuries. This review discusses the principles of MRI in the context of deep digital flexor tendon (DDFT) injury, comparing high-field and low-field systems and highlighting the clinical relevance of technical parameters, including field str...
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. Methods: A retrospective review was performed on all patients treated at Nassau University Medical Center, East Meadow, New York, for equestrian-related trauma from January 1, 2000, to December 31, 2024. Results: Twenty-nine equestrian trauma patients ages 10-70 were included, with injuries ob...

Methods: Medical records from 2014 to 2020 from the Equine Clinic Munich-Riem, Germany, and Auburn University Equine Ophthalmology Service identified horses diagnosed with IMMK following ophthalmic examination that had undergone InfraCG-PDT. Methods: Multiple intrastromal injections of EmunDo (InfraCG, A.R.C. Laser, Nuernberg, Germany) within an affected quadrant or the entire cornea were treated with diffuse diode laser energy (FOX A.R.C., Laser, Nuern...
Rodrigues APDC, Pozzobon R, De Bastiani G, De La Côrte FD, Azevedo MDS.Lameness, which arises from functional or structural changes in the limbs or axial skeleton, causes asymmetry in the movement of the equine head and/or pelvis. This study aimed to investigate the lameness patterns of horses that underwent lameness examination or monitoring during the years 2016 to 2020. This retrospective study used data from the lameness examination, evaluated using an objective assessment with body-mounted wireless inertial sensors. The lameness examination comprised clinical history, static inspection, palpation, gait evaluation (for which the animals were equipped with a w...
Quam V.Inflammation plays a role in acute and chronic equine tendon/ligament injury; anti-inflammatories are often indicated. Local corticosteroids provide consistent and profound short-term effects on pain and inflammation across species. However, there is no demonstrated benefit in the long term, and complications can occur. Alternative biologic anti-inflammatory treatments are available and should be used in horses at risk of complications. Nonetheless, corticosteroids remain an affordable and effective anti-inflammatory that, with continued research, may be indicated on a case-by-case basis as pa...
Vitale V, Velloso Álvarez A, de la Cuesta-Torrado M, Neira-Egea P, Vandecandelaere M, Tee E, Gimeno M, van Galen G.In human medicine, neurological diseases have been associated with transient cardiac abnormalities. In horses, myocardial disease is rarely diagnosed and has been associated with a wide variety of causes. The aim of this article is to describe three horses with no previous cardiac disease, which all developed severe cardiomyopathy following neurological disease. A 5-year-old Shetland pony stallion was diagnosed with cardiomyopathy with arrhythmias following an episode of seizures caused by an accidental intra-arterial xylazine injection. A 20-year-old crossbred mare was hospitalised for an ope...
Horan K, Pfau T.Racehorses and jockeys can incur injuries, not only during gallops, but also during routine trotting exercise to access gallop tracks or warm-up. Understanding how jockey position affects racehorse movement may influence safety, and this may vary across different surface conditions. This study used inertial sensing technology (XSens MTw sensors) and linear mixed models to quantify and determine the significance (p ≤ 0.05) of jockey riding position ('rising' versus 'two-point seat') and surface type (artificial, grass and tarmac) on: 1) time offsets between stance and flight phases; 2) ho...
Beaumont A, Emond AL, Pourcelot P, Fayaubot L, Ravary-Plumioen B, Dupays AG, Desquilbet L, Denoix JM, Crevier-Denoix N.To quantify changes in the cross-sectional area (CSA) of the midmetacarpal superficial digital flexor tendon (SDFT) in young Trotters during training. Unassigned: In this experimental study, 12 healthy 3-year-old French Trotters, assigned to either a soft-track or a hard-track group, were trained for 4 months (June through September of 2012 and 2013). Both groups followed the same exercise program of increasing intensity. Ultrasonographic examinations of both forelimb SDFTs of each horse were performed before the beginning of training (D0), after 2 months of training (M2), and after 4 months o...
Bonow S, Hernlund E, Eriksson S, Strandberg E, Gelinder Viklund Å.Sweden has a strong tradition of insuring horses for veterinary costs, and orthopedic diagnoses are the most common for insurance claims. The aim of this study was to investigate differences in prevalence and risk of orthopedic diagnoses for Swedish warmblood (SWB) horses classified as jumping (J) or dressage (D) horses. Also, other factors that may influence orthopedic health were investigated, i.e., sex, birth cohort, and participation in young horse tests and competition. The data consisted of 15,619 insured SWB horses born between 2010 and 2020. Horses were classified as J or D horses acco...
Pluim M, Reynolds A, McClure S.High-power laser therapy and extracorporeal shock wave therapy (ESWT) can be safely used to treat tendon and ligament injuries in horses, and the potential beneficial effects have been described. The power of low level lasers is not sufficient for treatment of tendon and ligament injuries in horses. ESWT is used more often to treat tendon and ligament injuries than it is for any other type of condition in horses, but there is limited supporting scientific evidence. Further research should focus on establishing dosage and treatment protocols for both laser therapy and ESWT in horses with clinic...
