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.
Verwilghen D, Easley J, Zwick T, Uhlhorn M, Grulke S, Simhofer H, Townsend N, Liyou O, Bodeus F, Zani DD, Vlaminck L, Pearce C, Staszyk C....Suture exostosis is an intriguing and not uncommon pathology that has to be included in the differential diagnosis for horses with swelling of the head. Although several singular case reports have been published, no large case series is available. The aim of this study is to report a multicentric retrospective collection of suture exostosis cases. Data concerning horses with suture exostosis in the facial region were collected retrospectively. Information regarding breed, age, gender, history, imaging findings, initiated treatment, response to treatment and follow up was recorded. One hundred ...
Gfrerer L, Michel S, Fürst AE, Piskoty G, Weisse B, Montavon S, Jackson MA. The goal of this study was to generate mandibular fractures in three regions of the diastema using a metal impactor to simulate a kick from a horse and to determine the mean deceleration in the initial phase of the impact event, the maximum contact force, the impact energy necessary to create a fracture and the duration of the impact. Methods: Thirty heads of horses aged between 5 and 20 years and euthanatized for various reasons were used. The heads were attached to a steel bar at the occiput at an axial angle of 45 degrees so that the body of the mandible was positioned horizontally ...
Nout-Lomas YS.Mechanisms of traumatic nervous system injury to a degree are similar, but differences exist in etiology, pathophysiology, and treatment of brain, spinal cord, and peripheral nerve injury. The most common clinical abnormalities seen in the horse are abnormal level of consciousness, abnormal behavior, seizures, cranial nerve deficits, vestibular disease, tetra- and paraparesis or paraplegia, cauda equina syndrome, specific gait deficits, and muscle atrophy. Treatments are directed toward reducing inflammation and swelling, halting secondary injury, and promoting mechanisms of neuroregeneration ...
Journée HL, Journée SL.Depending on the localization of the lesion, spinal cord ataxia is the most common type of ataxia in horses. Most prevalent diagnoses include cervical vertebral stenotic myelopathy (CVSM), equine protozoal myeloencephalitis (EPM), trauma and equine degenerative myeloencephalopathy (EDM). Other causes of ataxia and weakness are associated with infectious causes, trauma and neoplasia. A neurologic examination is indispensable to identify the type of ataxia. In addition, clinical neurophysiology offers tools to locate functional abnormalities in the central and peripheral nervous system. Clinical...
Furr MO.Neurologic disease of foals is a diagnostic and therapeutic challenge for veterinarians. Disease conditions such as neonatal encephalopathy are seen as well as developmental and congenital defects, bacterial infections, and trauma. Neonatal encephalopathy can be considered a "syndrome" with a variety of causes resulting in a similar clinical presentation. These causes can be categorized as maladaptation, hypoxic/ischemic encephalopathy, and metabolic abnormalities, all leading to signs of cerebral and brainstem disease. Spinal cord signs may occasionally be seen, but these signs are usually ov...
White A, Cullen P, Hinchion J.A stablehand in his 20s presented with increasing dyspnoea on exertion and chest pain months after being kicked directly in the chest by a horse. Further investigations revealed severe isolated, primary tricuspid regurgitation due to partial avulsion of the anterior leaflet. Open surgical repair was successfully performed from which he recovered uneventfully with resolution of his symptoms and minimal residual tricuspid regurgitation. Although uncommon, blunt force trauma to the chest is becoming increasingly recognised as a rare cause of tricuspid regurgitation. Symptoms may be insidious, and...
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...
Cunningham L, Agel J.Little information exists about horse-related injury admissions to Level 1 trauma centers in the Western United States. This study describes injury patterns in this population, to reveal potential areas for injury prevention initiatives. A retrospective database review of 512 non-fatal equine-related injuries over a 15-year period was conducted, using a Level 1 hospital trauma registry. To determine patterns of injury, patients injured by riding or being near a horse were classified according to age, sex, helmet use, abbreviated injury score, anatomical region injured, and length of stay. Equi...
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...
Stieger-Vanegas SM, Hanna AL.Computed tomography (CT) imaging of the head in equine patients is now commonly performed as CT scanners are more readily available. Head CT has proven valuable in evaluating spatially complex anatomic structures, where radiographic superimposition, or restricted access endoscopy or ultrasound, limit complete evaluation of the disease process. Head CT has been demonstrated to be incredibly valuable in the evaluation of dental and paranasal sinus disease, disease of the hyoid apparatus and ear, and in evaluation of skull trauma. CT is an excellent modality for assessment of both osseous and so...
Hall S, Smith R, Ramzan PHL, Head M, Robinson N, Parker R.Rib fractures in adult horses are poorly documented. Objective: To describe the presenting signs, diagnosis, treatment and outcome of horses diagnosed with rib fracture. Methods: Retrospective case series. Methods: The clinical records and diagnostic images of all adult horses diagnosed with a rib fracture at three referral centres over a 15-year period were reviewed. Results: Seventy-three horses met the inclusion criteria. Horses presented due to either resistance to ridden work and poor performance (n = 41), lameness (n = 21) or trauma (n = 7). In four horses, the presenting complaint...
Vajs T, Nekouei O, Biermann NM.The tarsus is one of the most common areas of traumatic injury with associated synovial involvement (SI) in horses. The aim of this retrospective study was to describe the clinical presentation, diagnostic procedures, management (emphasizing the type, duration, and route of antimicrobial administration), and outcome of cases with acute soft tissue trauma to the tarsal region. The presenting clinical features, the results of diagnostic modalities, and the initial response to therapy were assessed for their usefulness to predict SI. Medical records of 72 cases were included and SI was diagnosed ...
Riley CB, Rogers CW, Thompson KR, Guiver D, Padalino B.Negative outcomes associated with the road transport of horses are a significant welfare issue. This study aimed to describe the injuries sustained by horses during road transport in New Zealand and factors associated with trauma while in transit. New Zealand horse industry participants were surveyed on their horse transport experiences and equine industry involvement. Participants were solicited through horse organisations. The data were tabulated, and a logistic regression was performed to identify significant ( < 0.05) factors associated with transport-related injury. In total, 201/1133 ...
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...
Radcliffe RM, Hill JA, Liu SY, Cook VL, Hurcombe SDA, Divers TJ.Abdominocentesis is commonly used to evaluate the abdominal cavity of the horse. This technique provides valuable diagnostic information as well as the means to monitor patients with abdominal diseases being managed medically and to determine their need for surgical management. Complications are uncommon and include trauma to the gastrointestinal tract or spleen, septic peritonitis, or abdominal wall infection. Methods: This review describes the indications, utility, patient preparation, and instructions for performing abdominocentesis as well as possible complications reported in horses. Step...
Naef S, Steiger CN, Tabard-Fougère A, Dayer R, Ceroni D.Horse-related activities are increasingly popular among young people but are frequently associated with severe injuries requiring hospital treatment. There are few data on the incidence of equestrian injuries, especially in child populations, or on means of prevention. Thus, this study's purpose was to highlight the epidemiological data on specific injuries due to equestrianism and serve as the groundwork for future studies on the prevention of equestrian accidents. Methods: A retrospective study collected data on all children younger than 16 years old who attended our regional emergency depar...
Puolakkainen T, Marttila E, Thorén H, Snäll J.Patients with equine-related injuries (ERI) have high rates of hospitalization and often require surgical treatment. This study aimed to clarify the injury profiles of patients sustaining ERI-related craniofacial fractures and their relationship with other severe head and neck injuries.This retrospective study included all patients with craniofacial fractures admitted to a tertiary trauma center during 2013 to 2018. Out of 3256 patients, a total of 39 patients were included in the study (1.2%). Demographic and clinically relevant variables were reported and statistically evaluated.Males repres...
Dias IR, Maia LM, Quaresma M, Cotovio M, Silva FC.Complete fractures of the third metacarpal/metatarsal bones (Mc/t3) are not common, but can occur in various situations and all types of horses, contributing for approximately one third of all long bone fractures in the horse, mostly related to external trauma or to high energy injuries. To stabilize Mc/t3 fractures in the horse, conservative management with walking casts and/or open reduction and internal fixation techniques are referred in the scientific literature, these last one generally by double platting application to bone surface in 90 degrees. In the present case will be described a ...
Estrada McDermott J, Pezzanite L, Goodrich L, Santangelo K, Chow L, Dow S, Wheat W.Osteoarthritis (OA) is a common condition with diverse etiologies, affecting horses, humans, and companion animals. Importantly, OA is not a single disease, but rather a disease process initiated by different events, including acute trauma, irregular or repetitive overload of articular structures, and spontaneous development with aging. Our understanding of the pathogenesis of OA is still evolving, and OA is increasingly considered a multifactorial disease in which the innate immune system plays a key role in regulating and perpetuating low-grade inflammation, resulting in sustained cartilage ...
Samuels K, Bettis A, Davenport DL, Bernard AC.Nineteen million people participate in horseback riding activities in the US, and the horse industry employs more than 460,000 full-time workers. Emergency department data suggest young female amateurs and male professionals are most at risk of death from horse-related injuries. However, there has been no investigation into factors that may increase severe injury and mortality risk in these populations. This study investigates demographics and injury pattern differences between occupational and non-occupational horse-related injuries in the US. Methods: The 2017 American College of Surgeons Na...

Bhade P, Parsons A, Smiley A, Shreffler J, Nash N, Baker J, Harbrecht B, Huecker M.The potential for significant traumatic injury to individuals who interact with horses remains high due to animal size, forces applied, and unpredictability. Despite an estimated 30 million riders in the United States annually, few recent publications have addressed this patient population. Objective: This study describes characteristics of patients injured in interactions with horses, focusing on mechanism of injury and use of protective equipment. Methods: We queried our institution's trauma registry for all patients admitted for equine-related injuries (ERI) between January 1, 2013 and Dece...
Müller AC, Büttner K, Röcken M.Synovial structure involvement secondary to limb injury is a common emergency in equine practice, requiring an accurate initial diagnosis for immediate treatment. This study aimed to investigate the clinical usefulness of Serum amyloid A (SAA) in the initial diagnosis of synovial structure involvement caused by acute (<24 h) penetrating limb injuries in horses and to correlate SAA with standard diagnostic parameters. Fifty-five horses with acute limb injuries were divided into two groups: Group 1 (G1, n = 26) with a diagnosis of penetrating synovial trauma and Group 2 (G2, n = 29) without s...
Mutore K, Lim J, Fofana D, Torres-Reveron A, Skubic JJ.There is a paucity of evidence about traumatic injuries and their sequelae sustained due to equestrian injuries nationally. Methods: Retrospective study analyzing National Trauma Data Bank data from 2007 to 2016. Variables collected included age, sex, race, payer status, Injury Severity Score (ISS), hospital length of stay, Glasgow Coma Scale, systolic blood pressure (SBP) at presentation, discharge disposition, and mortality. Patient data were analyzed by anatomic region. Results: The most frequent type of injury was in the thorax, but head and neck injuries produced the highest mortality. In...
Stanbouly D, Besmer AV, Chuang SK.The purpose of our study is to assess the severity of craniomaxillofacial injuries from horseback-riding accidents. Methods: This is a 20-year retrospective cross-sectional study of the National Electronic Injury Surveillance System. Injuries from the activity of horseback-riding were included if they occurred in the craniomaxillofacial complex. Study predictors were derived from both patient and injury characteristics. The study outcome was the presence or absence (probability) of hospital admission from the emergency department. A multiple logistic regression model was created to model the o...
Launois T, Moor PL, Berthier A, Merlin N, Rieu F, Schlotterer C, Siegel A, Fruit G, Dugdale A, Vandeweerd JM.Traumatic limb injuries are common in horses. Negative pressure wound therapy (NPWT) has been proven to promote wound healing in human medicine. It has also been described for the treatment of wounds in horses. In this retrospective study, clinical records of 42 (n = 42) animals were assessed. Categories of wounds, duration of NPWT application, frequency of resetting the NPWT device, technical complications, and tolerance to the procedure were recorded. 42 wounds were classified as bony (n = 15; 36 %), articular (n = 14; 33 %), tenosynovial (n = 9; 21%), muscular (n = 2; 5%) and cuta...

Kilcoyne I, Nieto JE.For the equine veterinarian, orthopedic emergencies are a common occurrence in clinical practice, with traumatic wounds of the distal limb and penetrating injuries of the hoof being some of the most common medical conditions to affect horses. Intravenous regional limb perfusion is a technique widely used for the treatment of orthopedic infections in horses. The objectives of this review are to discuss some of the clinical applications for this treatment modality in the field and to review the technique for the practitioner.
Ivancic PC.We reported two cases of jockeys who sustained fracture/dislocation of the mid-thoracic spine due to traumatic falls during horse racing. We examined the injury mechanism based upon the patients' diagnostic images and video footage of races, in which the accidents occurred. Admission imaging of patient 1 (a 42 years old male) revealed T5 burst fracture with bony retropulsion of 7 mm causing complete paralysis below T5/6. There existed 22° focal kyphosis at T5/6, anterolisthesis of T5 relative to T6, T5/6 disc herniation, cord edema and epidural hemorrhage from T4 through T6, and cord injury f...

Methods: Medical records of horses at the Equine Clinic Munich-Riem, Munich, Germany and Auburn University, College of Veterinary Medicine were reviewed. Age, sex, breed, laterality, and clinical findings on ophthalmic examination, as well as an observed (confirmed) or unobserved (suspected) history of trauma, were recorded. Statistical analysis was performed to identify any correlation between clinical signs and blunt ocular traum...
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...
To assess injury patterns attributable to horse kicks, to raise the issue of preventive measures, and to evaluate the role of modern accident and emergency department computer software. Methods: Data analysis using a new kind of full electronic medical record. Results: Seventeen kicked equestrians were unmounted at the time of injury. Eight of seventeen patients sustained contusions of the extremities, the back, and the trunk. In nine patients an isolated facial injury was diagnosed. Five of nine patients needed referrals to the department of plastic surgery because of the complexity of the fa...
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...

Ingemarson H, Grevsten S, Thorén L.Riding accidents can be of a serious nature. Knowledge of risk factors is of essential value in the prevention of injuries. From the years 1969 through 1982 a series of 53 lethal riding injuries is analysed with reference to the rider, the horse, and the environment. Craniocerebral injuries dominate in this series, indicating the importance of adequately protecting helmets. Among the victims the female sex is dominating before the age of 25 and the males above this age. Older horses are less frequently involved in these accidents than younger ones. A long training period for riders under surve...
Pounder DJ.The fatalities associated with the riding and handling of horses in South Australia over the 11-year period 1973-1983 are reviewed. There were 18 deaths, including two sudden natural deaths in the saddle and one drowning. The 15 cases of horse-related trauma represent a death rate of approximately one per million population per annum. Thirteen of the deaths were the result of a head injury after a fall. Nine persons were not wearing protective headgear. The two principal groups at risk were male professional riders with a mean age of 32 years and female amateurs with a mean age of 19 years.
McIlwraith CW.Current concepts of pathogenesis, diagnosis, and treatment of equine degenerative joint disease are presented on the basis of recently acquired experimental and clinical knowledge. A number of concepts of pathogenesis need modification and the rationale of some of the newer treatments requires definition. Synovitis and other soft tissue changes are important components of the pathogenesis in addition to direct trauma to the articular cartilage. Loss of glycosaminoglycans constitutes an important biochemical "lesion" in the articular cartilage, making it weak and susceptible to trauma. Recognit...
Wong DM, Wilkins PA.Defining and describing the systemic inflammatory response syndrome (SIRS) and sepsis facilitated recognition and investigation of the complex disease processes involving the host response to infection and trauma. Over the years a variety of definitions of SIRS have been examined and applied to numerous research studies to improve critical care in both human and veterinary clinical practice. This article summarizes the history of the development of the SIRS definition, outlines the pathophysiologic processes that are involved in SIRS, and provides a specific definition for use in foal medicine...
Butler J, Rydell NW, Balazs EA.Twelve horses with traumatic arthritis were treated with intraarticular injection of hyaluronic acid mixed with cortisone and the results compared with 6 horses treated only with cortisone. There was a significantly better improvement in the group injected with a mixture of hyaluronic acid and cortisone. Further studies have given the same results in traumatic arthritis in horses if hyaluronic acid alone is injected. After injection of hyaluronic acid a large number of granulated monocytes appeared in the synovial fluid, but no inflammatory signs were observed. It is possible that this macroph...
Fortina M, Maniscalco P, Carulli C, Meccariello L, Colasanti GB, Carta S.Horse racing is a hazardous sport. We analyzed the incidence and characteristics of jockey injuries in a typical horse race. Methods: We analyzed all injuries sustained by 224 jockeys in the last 72 years. Results: It was found that in 96.1% of the races there was at least one fall and in 28.6% of the races 50% or more of the jockeys fell. In 43.4% of the falls, the jockey was taken to the emergency room. Comparing the Palio with traditional races in other countries, a higher injury incidence rate was observed for every 100 falls (109.884 vs 27-59) and a lower concussion rate/100 falls (0.97 v...
Whitlock MR, Whitlock J, Johnston B.A retrospective study of horse riding injuries in Berkshire was undertaken over a one year period from November 1983. The information was obtained from the Ambulance Service, the Jockey Club and the St. John Ambulance Brigade. There was a total of 103 injured persons with no deaths. Information from the Jockey Club was compared with the other two groups, the former sustaining more limb injuries and the latter more head injuries. A questionnaire was sent to all 42 ambulance patients. Thirty-eight had radiographs taken, 16 of which showed a fracture. Forty-one were wearing some form of hard hat,...
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...
Newton AM, Nielsen AM.The literature contains many studies on the types of injuries sustained in horseback riding incidents. Most advocate the use of equestrian helmets to prevent head trauma. However, information is limited on other specific prevention strategies. Methods: A 4-year, retrospective, and prospective review of medical records pertaining to horse-related injuries in a southwestern Colorado hospital yielded a sample of 85 patients who had been injured while riding or tending to horses. In addition to the record review, patients were interviewed during ED discharge, inpatient treatment, or in a follow-up...

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...
Robert N, Walzer C, Rüegg SR, Kaczensky P, Ganbaatar O, Stauffer C.The Przewalski's horse (Equus caballus przewalskii) was extinct in the wild by the mid 1960s. The species has survived because of captive breeding only. The Takhin Tal reintroduction project is run by the International Takhi Group; it is one of two projects reintroducing horses to the wild in Mongolia. In 1997 the first harem group was released. The first foals were successfully raised in the wild in 1999. Currently, 63 Przewalski's horses live in Takhin Tal. Little information exists on causes of mortality before the implementation of a disease-monitoring program in 1998. Since 1999, all dead...

Busch HM, Cogbill TH, Landercasper J, Landercasper BO.During the past 6 years 134 patients were admitted as the result of bovine (cow) and equine (horse) trauma. The mechanism of injury was fall from horse in 45 patients, animal assault in 42, animal kick in 39, and animal-drawn vehicle accident in eight. Injury Severity Score (ISS) ranged from 1 to 41 and was greater than or equal to 25 in 11 patients. One hundred seventeen operative procedures were performed by ten groups of surgical subspecialists. Mortality was nil. Ideal management of these injuries includes treatment in a regional trauma center and an educational program of preventive measu...
Ceroni D, De Rosa V, De Coulon G, Kaelin A.We report 4 cases of nutcracker fractures of the cuboid resulting from equestrian sport in pediatric population. These lesions are often consistent with a trauma in forced abduction of the forefoot. The particular mechanism of the cuboid fracture due to horseback riding in children is discussed. The methods used to radiographically evaluate the compression fracture of the cuboid and its associated injuries are presented. Left untreated, these fractures can lead to severe alterations in foot mechanics and function, such as to severe pain. In addition, the surgical treatment to correct the nutcr...

Papachristos A, Edwards E, Dowrick A, Gosling C.Despite a number of injury prevention campaigns and interventions, horse riding continues to be a dangerous activity, resulting in more accidents per hour than motorcycling, skiing and football. Injuries are often serious, with one in four patients requiring admission to hospital. This study aims to describe the severity of equestrian-related injuries (ERIs) using both clinical parameters and patient-reported outcomes. Methods: A retrospective study of all patients aged ≥18 years admitted to The Alfred Hospital between January 2003 and January 2008 with an ERI was performed. Specific clinica...
Marchand WR.Equine-assisted services (EASs) are being increasingly used as complementary interventions for military veterans who have experienced trauma. However, there is limited evidence of benefit for this population and almost no literature describing the desired potential outcomes and possible mechanisms of action. The aim of this article is to address these gaps by reviewing the extant literature of animal-assisted interventions in general, and equine-assisted services in particular, with the goal of providing guidance for future investigations in the field. Currently, the field is in the early stag...
Dixon PM, Tremaine WH, Pickles K, Kuhns L, Hawe C, McCann J, McGorum B, Railton DI, Brammer S.A review of 400 horses referred because of dental disorders showed 44 cases to suffer from primary disorders of their incisors and 11 from canine or 1st premolar teeth disorders. The remaining 345 horses suffered from primary disorders of the cheek teeth. Disorders of incisors included traumatic damage to teeth and their supporting bones, retained deciduous, displaced and supernumerary incisors; brachygnathia and abnormalities of wear, with most of the latter disorders being secondary to primary disorders of the cheek teeth Only 3 cases of apical infection of incisors were recognised. Most cas...
Tyler CM, Davis RE, Begg AP, Hutchins DR, Hodgson DR.Case records of 450 horses with signs of neurological disease are reviewed. One hundred and nineteen horses with neurological disease due to trauma were examined, of which 60 were due to spinal cord trauma, 47 to brain or cranial nerve trauma and 12 to peripheral nerve trauma. Cervical vertebral fractures/trauma were the most common injury. Basisphenoid/basioccipital bone fractures were the most common form of cranial trauma and facial nerve paralysis the most common cranial nerve injury. Eighty-nine horses with neurological disease due to malformation were examined. Cervical vertebral malform...
