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.
Physical therapy for the equine back. Before a physical therapy and rehabilitation program is suggested, the end requirement must be considered. All physiotherapeutic machines are subject to laboratory screening. In the United States, the approval of the Food and Drug Administration is required; in the United Kingdom, certification by the National Physics Laboratory has been required by law since January 1996. Laboratory experiments are continually conducted to examine and evaluate the effects on tissues of varied electrical waveforms, low-intensity electrical currents, sound waves, and light rays delivered by a variety of therape...
Medical management of back pain. The most common causes of back pain and their medical treatment are discussed. These include: dermatologic problems and conditions resulting from saddle trauma; discomfort and stiffness owing to injured paraspinal muscles; pain associated with supraspinous ligament damage; osseous pain and nerve dysfunction related to the spine and sacroiliac area; and neurologic diseases that can manifest as back pain. Bitting problems, cervical pain, and coexisting lameness are also considered.
Parotid duct laceration repair in two horses. Repair of parotid duct lacerations in 2 horses is described using intraluminal silastic tubing as a stent. The duct was lacerated traumatically at the facial vessel notch (incisura vasorum facialium) in the 1st horse, and iatrogenically after removal of an intraluminal sialolith after development of infection within the duct in the 2nd horse. In both cases, a silastic tube was passed retrograde into the duct via the salivary papilla, past the wound until the end lay rostroventral to the parotid salivary gland. The severed salivary ducts and the wounds were sutured. The external portion of the ...
Management of rupture of the gastrocnemius and superficial digital flexor muscles with a modified Thomas splint-cast combination in a horse. A 6-month-old warmblood filly had traumatic rupture in the gastrocnemius and superficial digital flexor muscles of the left hind limb. A modified Thomas splint-cast combination, which was custom fitted to the limb, was placed to prevent further disruption of the caudal reciprocal apparatus. The external coaptation device was removed after 21 days. The horse developed lesions consistent with osteochondrosis of the femoropatellar articulation within 8 weeks of the initial injury. Examination of the horse 6 months after injury revealed fibrous healing of the muscles and restoration of caudal reci...
Prevalence of traumatic myiasis in Hungary: a questionnaire survey of veterinarians. Veterinarians in Hungary were asked to complete a questionnaire on traumatic myiasis; of the 664 veterinarians contacted, 247 replied (37.2 per cent) and of these 209 (84.6 per cent) reported myiasis to be a problem among the livestock they treated. Infestation levels of > 10 per cent of animals were reported in sheep, cattle and horses. The myiasis season lasted from March to November with most cases reported in July and August. Significantly more respondents reported that fly larvae were present deep in wounds rather than superficially, consistent with infestations due to the obligate parasi...
Post traumatic keratouveitis in horses. 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...
Traumatic dental disease and soft tissue injuries of the oral cavity. Trauma to the oral cavity can result in an array of injuries affecting teeth, bone, and soft tissue. A thorough examination of the oral cavity is often facilitated by employing a full-mouth speculum after the horse has been tranquilized. Identification of broken, loose, or split teeth; fractures of the premaxilla or mandible; and avulsion or laceration of soft tissue structures such as the lips or tongue is usually straightforward. Treatment options vary depending on the structure involved; however, appropriate treatment generally results in a functional and cosmetically acceptable end result....
[Traumatology and sports injuries in equestrian acrobatics in the adolescent].
Sportverletzung Sportschaden : Organ der Gesellschaft fur Orthopadisch-Traumatologische Sportmedizin
The objective of this study was to compile knowledge of athletic injuries and complaint patterns related specifically to equestrian acrobatics (e.a.). A 20-page standardized questionnaire was sent to 114 e.a. participants. The mean age of the participants in e.a. groups was 15 +/- 3 years, that of independent participants 21 +/- 3 years. A total of 489 injuries was reported, mainly to muscles and tendons (35%), skin (33%) and joints and ligaments (25%). Bone injuries (6%) and head injuries (2%) were infrequent. Analysis of the localization showed that the head-face-neck region was involved in ... Exercise-induced pulmonary haemorrhage (EIPH) in horses results from locomotory impact induced trauma–a novel, unifying concept. Exercise-induced pulmonary haemorrhage (EIPH) in horses, although of major welfare and economic importance worldwide, is of uncertain cause. It is accepted that the dorsocaudal region of the lung is particularly prone to the condition, but present theories of causation cannot satisfactorily explain the mechanism or pattern of occurrence. We propose that EIPH results from locomotory impact induced trauma; the mechanism being similar to that producing lung tissue damage following thoracic impact injury. In impact injury, the localised impulsive load on the chest wall is transmitted by pressure w...
[Dimethylsulfoxide (DMSO) in horses: a literature review]. The use of dimethyl sulphoxide in equine medicine is discussed with special reference to trauma of the central nervous system, chronic endometritis, trauma of the locomotor apparatus, and ischaemic bowel pathophysiology. The ability of dimethyl sulphoxide to reduce connective tissue formation might be of interest in abdominal surgery. The anti-inflammatory effect of dimethyl sulphoxide is used in the treatment of muscle trauma, tendinitis, laminitis, and arthritis. Dimethyl sulphoxide can potentiate the effects of other drugs. The most common dose is 1 g/kg body weight intravenously up to a 40...
[Acute blindness due to trauma in a Welsh pony-colt]. A healthy, 10-day-old Welsh A pony colt was totally blind 1 day after arrival at a studfarm. Both eyes appeared normal on external inspection. The young animal had been very distressed during the 40-km journey to the studfarm. Intravenous corticosteroids were administered for 2 days, but did not result in any observable improvement. The animal was euthanized at the owner's request. Both eyes with the optic nerves were removed for histological examination. Both optic nerves showed Wallerian degeneration, a well-known response of peripheral nerves to trauma. The foal, which was not tethered duri...
Effects of experimental desmotomy on material properties and histomorphologic and ultrasonographic features of the accessory ligament of the deep digital flexor tendon in clinically normal horses. To evaluate posttrauma biomechanical behavior of the scar attributable to desmotomy of the accessory ligament of the deep digital flexor tendon (AL-DDFT), compared with the histomorphologic and ultrasonographic appearance. Methods: 5 Standardbred trotters. Methods: Gross appearance, length, cross-sectional area (CSA), in vitro material properties, and ultrasonographic and histomorphologic features were studied 6 months after desmotomy. Tensile tests were conducted, with forces and elongation simultaneously recorded. Surgically treated limbs were compared with nontreated contralateral limbs. Re...
Recidivism in equestrian trauma. A 3-year chart survey and questionnaire was conducted of equestrian-injured patients at a regional trauma center to determine patterns and consequences of injury and rate of recidivism. Ninety-two patients (95 encounters) were treated; most were young (mean age, 27 +/- 11 years) women (84%) riders sustaining falls (80%). Most injuries were orthopedic (47%); 19 per cent of patients required hospital admission. There was one death. Helmet use was documented in only 34 per cent. Eighty-one per cent of patients responded to a follow-up telephone survey; 36 per cent recounted additional accidents (...
The pathophysiology of osteochondrosis. 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...
Fatal and non-fatal farm injuries to children and adolescents in the United States, 1990-3. Examine the current magnitude of the injury problem to children and adolescents on farms, and to compare these data to that from 1978-83. Methods: US National Center for Health Statistics Mortality Multiple Cause of Death Tapes for the years 1991-3, and the US Consumer Product Safety Commission National Electronic Injury Surveillance System for data on emergency department visits for 1990-3. Methods: Children and adolescents 19 years and younger injured on farms. Results: There were an average of 104 deaths per year due to injuries occurring on farms. The rate of 8.0 deaths per 100,000 child f...
Head, face, and neck trauma from large animal injury in New Mexico. Head, face, and neck injuries (HFNI) occur during animal-related trauma. We compared patients with HFNI and without HFNI after animal-related injuries to determine the significance of these injuries. Methods: Retrospective review of admissions for animal injuries between January 1, 1990, and December 31, 1995, by age, gender, mechanism, animal, Glasgow Coma Scale (GCS) score, Injury Severity Score (ISS), Abbreviated Injury Severity score for head and neck (AIS Head/Neck), AIS score for face (AIS Face), intensive care unit stay, hospitalization length, morbidity, and mortality. Results: There w...
Major pelvic injuries in equestrian sports. A series of pelvic and acetabular injuries caused by horse riding accidents is reported. The importance of wearing appropriate protective clothing when riding is emphasised.
Persistent penile prolapse associated with acute blood loss and acepromazine maleate administration in a horse. Prolonged penile prolapse in horses has been reported in association with administration of phenothiazine tranquilizers, trauma, neuropathies, severe general debilitation or exhaustion, starvation, rabies, herpes myeloencephalitis, equine infectious anemia, and purpura hemorrhagica. A 5-year-old gelding was admitted for treatment of prolonged penile prolapse of 12 days' duration that developed after acepromazine maleate was administered to allow examination of a laceration that had resulted in severe blood loss. The horse was sedated, and the penis was replaced in the preputial cavity by use o...
Management of rectal tears. Rectal tears have important medicolegal implications, and severe tears have a poor prognosis. Prompt diagnosis, immediate application of first aid measures, early referral, use of appropriate definitive treatments, and aggressive aftercare will improve the prognosis. The grade of rectal injury will determine the definitive treatment, but there are few guidelines to determine which treatment is best in each case. Bypass procedures, such as colostomy and indwelling rectal liner, have their own advantages and disadvantages, but can facilitate healing and prevent life-threatening complications if ...
Equine-related neurosurgical trauma: a prospective series of 30 patients. Thirty million Americans ride horses; 50,000 of these riders are treated in emergency rooms annually. Equestrian activities are uniquely dangerous because the participant is unrestrained, often helmetless, and riding large, unpredictable animals capable of 40-mph speeds and kicking with up to 1 ton of force. Neurologic injuries in equestrians constitute the majority of severe injuries and fatalities. We prospectively studied all patients admitted to the University of Kentucky Medical Center with equine-related neurosurgical trauma from July 1992 to January 1996. Eighteen of 30 patients were ma...
Ocular diseases of llamas: 194 cases (1980-1993). To identify ocular and adnexal diseases to which llamas in North America are susceptible, to determine prevalence of these diseases in llamas, and to compare prevalences of the major ocular diseases of llamas, cattle, and horses. Methods: Retrospective study. Methods: 194 llamas, 4,937 cows, and 11,950 horses with ocular disease. Methods: Medical records of all llamas entered into the Veterinary Medical Database between 1980 and 1993 were reviewed. Data on ocular structures affected and types of ocular disease were compiled. Prevalences of uveitis, corneal ulcers, and ocular squamous cell carc...
Surgical repair of the parotid gland in a gelding. The surgical repair of a traumatic injury to the parotid (Stenson's) duct of an adult horse is described and compared with previous reports. The diagnosis was confirmed by the analysis of a flow of saliva-like fluid observed while the horse was eating. The repair was attempted under general anaesthesia three days after the injury. Surgical anastomosis was considered to have improved the rate of healing. However, there was some evidence of leakage of saliva from the site for three days after the removal of the in-dwelling catheter, seven days postoperatively. A full recovery followed.
Comparison of collagen fibril populations in the superficial digital flexor tendons of exercised and nonexercised thoroughbreds. This study was undertaken to test the hypothesis that collagen fibrils, the submicroscopic units of strength in tendon, would hypertrophy in response to a specific defined training programme. Fibril diameters were measured in central and peripheral regions of superficial digital flexor tendon (SDFT) samples from five 18-month-old horses which underwent a subsequent 18 month training programme and 6 age- and sex-matched controls. Central region fibrils from the trained horses had a mass-average diameter (MAD) of 105.3 nm, which was significantly lower (P < 0.01) than that of 131.7 nm for the...
Visual outcome and ocular survival following iris prolapse in the horse: a review of 32 cases. The medical records of 32 horses treated for iris prolapse (IP) during an 8 year period, at the University of Florida Veterinary Medical Teaching Hospital, were reviewed. Iris prolapse was associated with perforated corneal ulcers in 15 horses (47%), ruptured stromal abscesses in 2 horses (6%), and full thickness corneal lacerations in 15 horses (47%). Initial ophthalmic examinations revealed IP with severe iridocyclitis in all eyes and keratomalacia in 8 eyes with corneal ulcers, one with a stromal abscess and 1 with a corneal laceration. Hyphema was present in 7 eyes with corneal lacerations...
Lateral collateral ligament avulsion of the humeroradial joint in a horse. This report describes traumatic avulsion of the lateral collateral ligament of the humeroradial joint in a horse. The history and diagnostic procedures are included with relevant radiographs and ultrasonographs. The poor prognosis associated with this injury is due to degenerative joint disease.
Intracranial hematoma in experienced teenage equestrians. Intracranial hematoma in pediatric equestrians is rare, notwithstanding the lack of uniform standards and requirements for the use of protective headgear during equestrian events. We report two teenage helmeted equestrians who sustained severe head trauma with intracranial hematoma due to falls during equestrian events. Current recommendations for the use of equestrian headgear are reviewed.
Penetrating wounds of the thorax in 15 horses. Clinical features, treatment and outcome of 15 horses with penetrating thoracic wounds are described. The most common cause of trauma was collision with an object (10 horses). Concurrent clinical findings included subcutaneous emphysema (12 horses), pneumothorax (12 horses), haemothorax (5 horses) and pneumomediastinum (6 horses). Axillary wounds were present in 5 horses. Foreign bodies were identified and removed from 2 horses. Wounds were sutured (6 horses) or packed (7 horses). Air was evacuated from the pleural cavities of 11 horses. Eleven horses (73%) were discharged from the hospital. A...
