Topic:Trauma
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.
Fire and smoke inhalation injury in horses. Although not common in horses, fire and smoke inhalation trauma may require veterinary assistance at several levels. Most commonly, the equine clinician is called on to provide care of potentially complex and emotionally charged cases. Thermal injury, along with smoke inhalation, can cause local and diffuse lesions. Massive tissue edema may occur, which can be a challenge to manage as well as creating organ dysfunction at distant sites. Further complications of severely affected patients are varied and include life-threatening sepsis. This article reviews some of the important features of this...
Thoracic trauma in horses. Thoracic trauma represents an important cause of morbidity in mortality after injury in human beings and animals. After any form of suspected chest wall trauma, initial emergency management should include assurance of a patent airway and adequate ventilation, along with treatment for shock if present. As with any open wound, tetanus prophylaxis should be instituted. Types of trauma to the thoracic region of the horse include pectoral and axillary lacerations, penetrating chest wounds, flail chest, fractures of the ribs, blunt thoracic trauma, and several potential sequelae that include pneumot...

Ophthalmic emergencies in horses. The emergency clinician is frequently in the position of receiving, evaluating, and initiating treatment on horses with ophthalmic emergencies or orbital trauma. In the best of circumstances, an ophthalmologist is available to guide initial therapy and ultimately assume responsibility for the management of the patient during the remainder of its hospitalization, but this is not always the case. The information presented here is meant to provide the emergency clinician with basic guidelines for the initial assessment and management of horses sustaining ocular injuries or presented with an ophth...
Field fracture management. Emergency management of distal limb and skull fractures in horses is vital to the successful outcome of these cases. Distal limb fractures, in particular, require careful assessment and counseling of the owner as well as adequate stabilization or coaptation of the fracture. Horses with limb or skull fractures may also have concurrent pain, blood loss, and other fluid losses that can result in shock requiring fluid therapy before definitive treatment of the fracture. Proper emergency fracture stabilization, initial treatment in the field, and patient transport are discussed.

Objective: To describe clinical, radiographic and ultrasonographic findings related with rib fractures in newborn foals in an equine critical care unit; and to compare diagnostic accuracy of ultrasonography to radiography. Methods: A prospective ultrasonographic study was performed on 29 foals presented to the emergency unit. This study was performed at the Centre Hospitalier Universitaire Vétérinaire (CHUV), University of Montreal. Physical examination as well as radiograph...
Pathologic findings in reintroduced Przewalski’s horses (Equus caballus przewalskii) in southwestern Mongolia. 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...
The horse-racetrack interface: a preliminary study on the effect of shoeing on impact trauma using a novel wireless data acquisition system. There is a need to determine accelerations acting on the equine hoof under field conditions in order to better assess the risks for orthopaedic health associated with shoeing practices and/or surface conditions. Objective: To measure the acceleration profiles generated in Thoroughbred racehorses exercising at high speeds over dirt racetracks and specifically to evaluate the effect of a toe grab shoe compared to a flat racing plate, using a newly developed wireless data acquisition system (WDAS). Methods: Four Thoroughbred racehorses in training and racing were used. Based on previous trials, e...
The importance of proper shoe gear and safety stirrups in the prevention of equestrian foot injuries. The aim of this study was to compile specific foot injuries occurring in pediatric patients that result from equestrian sports and to highlight the importance of wearing adequate riding boots to protect the feet. During a 12-year period, 258 children were admitted to Children's Hospital of Geneva for injuries resulting from horseback riding. Amongst these children, 8 sustained foot lesions that required hospital admission. Four children had compression-type fractures of the cuboid (nutcracker fracture of the cuboid) associated with other complex midfoot fractures, 2 had Lisfranc fracture dislo...
Deep digital flexor tendon shortening as a treatment for distal interphalangeal joint hyperextension in a 2-year-old mare. Shortening of the deep digital flexor tendon was performed by tenotomy, overlapping and anastomosis. The procedure was performed on a two-year-old Quarter Horse Mare with distal interphalangeal joint hyperextension with subluxation and metatarsophalangeal joint hyperextension. These problems originated from damage to the digital flexor tendons, presumably due to previous distal limb trauma. The procedure markedly improved the mare's level of comfort, degree of ambulation and limb conformation. Two years following surgery the mare was comfortable at pasture.
Changes in central venous pressure and blood lactate concentration in response to acute blood loss in horses. To evaluate selected hemodynamic, blood gas, and biochemical responses to mild to moderate acute blood loss in standing, awake horses. Methods: Prospective study. Methods: 7 healthy mares. Methods: Each horse was restrained in standing stocks, and its head was maintained in a neutral position; sedatives and tranquilizers were not administered. During a 1-hour period, blood was collected into collection bags by use of a suction pump. The rate of blood collection was approximately 16 mL/kg/h (7.3 mL/lb/h). Thirty minutes after blood collection, the blood was readministered at the same rate. Cent...
Dental and orofacial trauma in pony and horseback riding children. An epidemiological survey was carried among pony and horseback riding children in nine pony and horseback riding clubs, Istanbul. The purpose of the present study was to evaluate the prevalence of dental trauma in young pony and horse riders. A total of 214 children were interviewed to determine the occurrence of dental trauma during pony and horseback riding. Some 2.3% of participants (n = 5) had already been affected by dental and orofacial trauma. Horse riders experienced dental and/or orofacial trauma significantly more than the pony riders. Results revealed that these children's awareness...
Five year analysis of Jockey Club horse-related injuries presenting to a trauma centre in Hong Kong.

In addition, the equestrian events of the 2008 Beijing Olympic Games will come to Hong Kong. This study analysed the pattern of horse-related injury among patients who presented to a trauma centre in a teaching hospital in Hong Kong. Methods: Information from the trauma centre database was analysed retrospectively. The database includes trauma patients who had sustained potentially severe injuries that warranted initial assessment and resuscit...
Use of magnetic resonance imaging to diagnose distal sesamoid bone injury in a horse. A 5-year-old Appaloosa mare was examined for severe left forelimb lameness of 4 months' duration. Results: Lameness was evident at the walk and trot and was exacerbated when the horse circled to the left. Signs of pain were elicited in response to hoof testers placed over the frog of the left front hoof, and a palmar digital nerve block eliminated the lameness. Radiographs revealed no abnormalities, but magnetic resonance imaging (MRI) revealed increased bone density in the medullary cavity of the distal sesamoid (navicular) bone in the proton density and T2-weighted images and a defect in the...
Limb fractures more common in French than British jockeys. French jockeys suffer more severe injuries when they fall off their horses than their British counterparts. While it has been shown that jockeys suffer high rates of fatal and non-fatal injuries, little is known about differences in injury rates between countries. To investigate this, researchers from Australia, France and the UK used prospectively collected data on the rates of fatal and non-fatal injuries in flat and jump jockeys in France and compared them with data from the UK.
Surgical and traumatic wound infections, cellulitis, and myositis in horses. Surgical site infections (SSIs) and traumatic wound management remain challenging clinical scenarios. The prevention of SSIs involves meticulous surgical technique and aftercare. Traumatic wounds require thorough evaluation to assess the involvement of synovial structures and radiographs to check for fractures. Chronic wounds can require a biopsy and histologic evaluation to obtain a diagnosis, because many underlying pathologic processes grossly appear similar but different treatment regimens are required. Early recognition and diagnosis of cellulitis and myositis enable the rapid aggressive ...

Results: Thirty-six spine fract...
An unlucky horseshoe: blunt aortic rupture after horse kick. The majority of blunt aortic injuries (BAIs) are related to "rapid deceleration"mechanisms with motor vehicle crashes (MVCs) and falls accounting for the majority of these injuries. However, in recent years improved understanding of the mechanisms behind blunt aortic injury has led
to an expansion of the "usual suspects" when evaluating blunt thoracic injury. Compression of the thoracic cage has proven to have a significant potential for blunt aortic injury, even in
instances without "high-speed" mechanisms commonly sought when explaining the history for BAI risk factors. In this we report, ...
