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.
Mechanisms and patterns of injuries related to large animals. Injuries from encounters with large animals represent a significant health risk for rural communities. We evaluated our regional trauma centers' experience with large-animal injuries to determine whether certain mechanisms and patterns of injury predicted either major head/craniofacial or torso (chest/abdomen/pelvis) trauma. Methods: The hospital courses of 145 patients with injuries related to large animals were reviewed retrospectively to determine patterns of injury, specific injury mechanisms, species-specific injuries, and predictors of multiple body region trauma. Results: Seventy-nine p...
Jockey injuries in the United States. In the sport of horse racing, the position of the jockey and speed of the horse predispose the jockey to risk of injury. Objective: To estimate rates of medically treated injuries among professional jockeys and identify patterns of injury events. Methods: Cross-sectional survey from data compiled by an insurance broker. Information on the cause of injury, location on the track, and body part injured was evaluated. Methods: Official races at US professional racing facilities (n = 114) from January 1, 1993, through December 31, 1996. Methods: A licensed jockey population of approximately 2700 pe...
Equine dental disease. Part 3: A long-term study of 400 cases: disorders of wear, traumatic damage and idiopathic fractures, tumours and miscellaneous disorders of the cheek teeth. Of 400 horses referred because of dental disorders, 349 cases were diagnosed as suffering from primary disorders of their cheek teeth. Details of 104 of these cases are presented, including 44 cases with abnormalities of wear, 26 cases with traumatic damage, 24 cases with idiopathic fractures and 10 cases with miscellaneous cheek teeth disorders including oral tumours. The long-term response to treatment was excellent in most cases, even in cases with residual secondary periodontal disease.
Modelling impact-initiated wave transmission through lung parenchyma in relation to the aetiology of exercise-induced pulmonary haemorrhage. Recently we proposed that exercise-induced pulmonary haemorrhage (EIPH) results from locomotory-impact-induced trauma by impact of the scapula on the chest wall during footfall and the consequent transmission of waves through the lung. A computational model has been developed to demonstrate that wave amplification and focusing occur in the dorsocaudal tip of the lung for waves originating on the anterior subscapular surface. The propagation of an acoustic wave was investigated in a simplified 2-dimensional representation of a vertical anterio-dorsal section of horse lung. It was demonstrated t...
Injuries to polo riders: a prospective evaluation. To assess prospectively the incidence, nature, and severity of injuries to polo riders competing in the 1996 Argentine High Polo season. Methods: Assessment, documentation, and provision of care for all injuries sustained during the 1996 season by one of the authors. Riders were also surveyed retrospectively for their previous polo injuries. Results: 34 riders took part in the study. Nine injuries were sustained prospectively and 55 injuries were reviewed retrospectively (64 total). The injuries were categorised as minor (10), moderate (13), and major (41). Twenty five (39%) injuries occurred ...
Equine dental disease part 1: a long-term study of 400 cases: disorders of incisor, canine and first premolar teeth. 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...
Intramuscular desmoid tumor (musculoaponeurotic fibromatosis) in two horses. Intramuscular desmoid tumors (musculoaponeurotic fibromatosis) were discovered in two young adult horses. The tumor in one horse was in the lateral cervical musculature, and that in the second horse occurred in the pectoral musculature. Histopathologic features were similar in both horses and included proliferation of fibroblasts and cells expressing muscle actin (myofibroblasts), with extensive dissecting fibrosis within muscle. These features are similar to those of desmoid tumors in humans, particularly those also known as musculoaponeurotic fibromatosis. Dissection of these lesions reveale...
Comparison of intra-articular injection of 2 ml of 0.9% NaCl solution with rest alone for treatment of horses with traumatic arthritis. To compare effects of intra-articular injection of 2 ml of 0.9% NaCl solution with rest alone for treatment of horses with traumatic arthritis. Methods: 38 Standardbred horses with moderate to severe lameness that resulted from traumatic arthritis. Methods: Horses were stratified on the basis of number of affected joints. In each stratum, horses were allocated randomly to treatment groups (intraarticular injection of 2 ml of 0.9% NaCl solution vs rest only). Treatment was for a period of 3 weeks. Horses were inspected weekly with a final examination 2 to 4 weeks after completion of treatment. ...
[Possibilities for computer tomography of the equine head based on two cases with a fracture of the base of the skull]. For the past 2 years computed tomography is used at the Veterinary School, University of Zürich. This new imaging modality enables the detection of abnormalities occurring in small and large animals which were previously not visible with imaging techniques. Subjects of this study were a foal and a small pony, both with suspected head trauma. Routine radiography could not explain any of the neurological deficiencies. In the first case a basilar skull fracture along with a focal brain hemorrhage was detected, in the second case multiple basilar skull fractures were seen. The computed tomographi...
Injuries to riders in the cross country phase of eventing: the importance of protective equipment. To determine the distribution of injuries in the eventing discipline of equestrian sports and the effectiveness of the protective equipment worn. Methods: Data on all injuries sustained in the cross country phase over fixed obstacles were collected from 54 days of competition from 1992 to 1997. This involved 16,940 rides. Results: Data on a total of 193 injuries were collected, which included two deaths. This represents an injury rate of 1.1%. Head and facial injuries represented the largest group (31%), with one third of these requiring treatment in hospital. All riders were wearing protectiv...
Nonsurgical treatment of suprascapular nerve injury in horses: 8 cases (1988-1998). To determine the outcome of horses with suprascapular nerve injury treated with stall rest alone. Methods: Retrospective case series. Methods: 8 horses. Methods: Information on signalment, history, limbs affected, severity of lameness, degree of muscle atrophy, gait abnormalities, and results of radiography and electromyography was obtained from medical records. All horses were treated with stall rest. Follow-up information on severity of lameness, gait abnormalities, degree of muscle atrophy, time between injury and resolution of gait abnormalities, and outcome was obtained during reexaminati...
Immediate and persistent complete heart block following a horse kick. Nonpenetrating chest trauma has been reported to cause acute and transient disorders of impulse formation and propagation, including intraventricular conduction delay and heart block. We report a case of immediate and sustained complete heart block following blunt chest injury.
Use of a temporary indwelling ureteral stent catheter in a mare with a traumatic ureteral tear. A 4-year-old primiparous Thoroughbred mare was referred for treatment of uroperitoneum subsequent to dystocia. Hematologic and serum biochemical analyses revealed values consistent with those reported for foals with uroperitoneum. Exploratory celiotomy revealed the source of the uroperitoneum to be a rent in the right ureter proximal to the trigone of the bladder. Substantial accumulation of urine in the tissues surrounding the ureter prevented accurate identification and repair of the defect, so a temporary indwelling ureteral stent catheter was inserted. Three weeks later, the stent catheter...
Equestrian injuries in the paediatric age group: a two centre study. This study's objective was to examine the nature, cause and frequency of injury resulting from equestrian sport in paediatric patients attending two accident and emergency departments. We recorded the attendances of patients aged less than 16 years with equestrian-related trauma in 1 year. Demographic details, injury, mechanism of injury, rider experience and use of protective equipment were noted. There were 41 attendances (39 female, two male, median age 12 years). Thirty-one were injured while mounted, 10 while dismounted. The commonest group of injuries were soft tissue injuries of the low...
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 par...
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...
