Topic:Injury
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.
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.
Chronic tenosynovitis of the carpal extensor tendon sheaths in 15 horses. The history, clinical features, radiological findings, treatment and outcome of 15 horses with chronic tenosynovitis of the carpal extensor tendon sheaths are reported. The condition was seen most commonly in horses used for jumping and penetration of the tendon sheaths by thorns was the most common aetiology. Treatment involved surgical resection of the hyperplastic synovial membrane, and adhesions within the tendon sheath, with primary closure. When combined with early postoperative physiotherapy this was found to be an effective method of treatment. All horses in this series were not lame a...
Comparison of racing performance before and after treatment of incomplete, midsagittal fractures of the proximal phalanx in standardbreds: 49 cases (1986-1992). To assess the effect of incomplete, midsagittal fractures of the proximal phalanx (P1) on racing performance in Standardbreds. Methods: Retrospective cohort study. Methods: 49 Standardbred horses admitted to the George D. Widener Hospital for Large Animals between July 1986 and December 1992 with a definitive radiographic diagnosis of an incomplete, midsagittal fracture of P1 and a known method of treatment. Methods: Performance index and racing time were compared before and after diagnosis and treatment of fracture, using ANOVA that controlled for the effects of horse, gender, age, track leng...
Use of statistical models to evaluate racing performance in thoroughbreds. To develop a statistical model to evaluate the influence of specific parameters on racing performance in Thoroughbreds. Methods: Survey. Methods: Racing records of Thoroughbreds performing in Louisiana from 1981 to 1985. Methods: Race results for 20 randomly selected days from 5 racetracks during 5 years were analyzed, using regression analysis. Results: The most influential parameter was distance raced. There were significant differences in racing performance among horses at different tracks. At the tracks examined, fast racing surfaces resulted in significantly faster finish times than good ...
Skeletal origins of exercise intolerance in horses. Skeletal origins of exercise intolerance and performance failure can reside in multiple tissues. Diagnosis of injury that results in an ability to continue to exercise, yet inefficiently do so, requires familiarity with evaluation of subtle lameness and often with the specific demands of the different equine sports. Imaging is usually vital to diagnosis development and understanding of lesion influences on locomotion. Therapy is lesion dependent. Return to competitive exercise and performance is dictated by an understanding of skeletal tissue response to injury, rational progressive treatment,...
Effect of sodium bisulfate on ammonia concentration, fly population, and manure pH in a horse barn. To evaluate the effectiveness of altering the pH of manure with sodium bisulfate, thereby decreasing ammonia concentration and fly population in a horse barn environment. Methods: 4 mixed-breed pony stallions. Methods: The 4-week study was scheduled with 2 weeks of treatment (with 2 application rates) and 2 weeks with no treatment (control weeks). During treatment weeks, sodium bisulfate was applied daily to the top of the bedding and straw, then spread on top. Ponies were kept in the stalls 24 hours a day during the 7-day test period and stall cleaning was not done. On day 7 of each week, amm...
Treatment of a comminuted frontal-plane fracture of the distal phalanx in a horse. Successful treatment of a comminuted frontal plane fracture of the distal phalanx in a horse is described. The bone fractured through the solar canal, close to the insertion of the deep digital flexor tendon. A hoof case was used to reduce bending and tensile stresses on the solar surface by limiting expansion of the hoof wall during weightbearing. In addition, the heel was elevated, using 3 degrees wedge pads incorporated within the hoof cast, to reduce distraction at the fracture site caused by the pull of the deep digital flexor tendon. Two casts were used over a 4-month period. Complete ra...
High-speed exercise history and catastrophic racing fracture in thoroughbreds. To investigate the relation between several racing speed history characteristics and risk of fatal skeletal injury (FSI) in racing Thoroughbreds. Methods: 64 Thoroughbreds euthanatized during a 9-month period in 1991 at a California racemeet because of a catastrophic fracture incurred while racing (cases), identified retrospectively. For each race in which an FSI occurred, 1 control horse was randomly selected from the noncatastrophically injured participants. Methods: Racing and officially timed workout histories were obtained for each horse. Several history characteristics were calculated to...
Treatment of acute superficial digital flexor tendon injury in horses with polysulphated glycosaminoglycan. Horses with acute injuries of the superficial digital flexor tendon were treated with a course of seven intramuscular injections of 500 mg of polysulphated glycosaminoglycan at four-day intervals. Clinical assessments of the lesions were made by a veterinary surgeon at the time of each injection and 14 and 28 days after the last injection. A total of 150 courses of the drug were administered and adequately completed assessment forms were returned for 80 cases. Long-term follow-up data were obtained for 19 cases. The subjective assessments by the veterinary surgeons showed that in 80 per cent o...
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.
In vitro determination of equine third metacarpal bone unloading, using a full limb cast and a walking cast. To improve fracture treatment, in vitro experiments were performed to study the influence of a full limb cast and a walking cast on the loading regimen of bones in the distal portion of the equine forelimb. Methods: 6 forelimbs of 6 Shetland ponies. Methods: Loading of the third metacarpal bone was considered a representative measure for distal limb loading. Electrical resistance rosette strain gauges were attached to the dorsal, palmar, medial, and lateral surfaces of the midshaft of this bone in 6 forelimbs of 6 Shetland ponies. The limbs were tested in a pneumatic loading device to a maxima...
A retrospective evaluation of the surgical management of equine carpal injury. Records of 220 thoroughbred horses presented to the Randwick Equine Centre or the University of Queensland Veterinary Teaching Hospital for surgical management of carpal injury were reviewed. Details of racing performance were obtained, enabling evaluation of racing success following surgery. Age and sex matched control horses not known to have suffered carpal injury were selected from the Australian Stud Book and the Australian Racehorse Register. Control and treated populations were compared in terms of overall career racing success. Radiographs or xeroradiographs from 198 horses were availa...
Preventing equestrian injuries. Locking the stable door. The medical and sports literature databases were searched for equestrian sports-related injury published in English since 1980, together with conference abstracts and discussions with equestrian sporting bodies. This literature was critically reviewed, with emphasis on measures to prevent or control injury i.e. countermeasures. While there is considerable literature available on the epidemiology of injury incurred in most equestrian sports, there is little on the prevention of these injuries. Case-control or other studies evaluating the effectiveness of the countermeasures suggested by authors...
Horseshoe characteristics as possible risk factors for fatal musculoskeletal injury of thoroughbred racehorses. To evaluate selected shoe characteristics as risk factors for fatal musculoskeletal injury (FMI) and specifically for suspensory apparatus failure (SAF) and cannon bone condylar fracture (CDY) of Thoroughbred racehorses in California. Methods: Case-control study. Methods: Thoroughbred racehorses (n = 201) that died of were euthanatized at California racetracks between August 1992 and July 1994. Methods: Shoe characteristics were compared between case horses affected by FMI (155), SAF (79), and CDY (41) and control horses that died for reasons unrelated to the appendicular musculoskeletal syste...
Evaluation of an autologous tendon graft repair method for gap healing of the deep digital flexor tendon in horses. A sutured tenorrhaphy technique that incorporated an autologous tendon graft was compared mechanically and histologically with a sutured tenorrhaphy at 6, 12, and 24 weeks after repair. Tenorrhaphy was performed in the forelimb tendon of the deep digital flexor muscle and the graft was taken from the hindlimb tendon of the lateral digital extensor muscle; one forelimb site included the graft, whereas the other forelimb site was not grafted. Tenotomies were made immediately proximal to the insertion of the accessory ligament into the tendon of the deep digital flexor muscle. Grafted and nongraf...
Heavy metal concentrations in injured racehorses. Records were reviewed of horses that had fatal injuries at California racetracks over a 16-mo period. Horses were categorized based on injury type, sex, age and breed. Arsenic, cadmium, copper, iron, lead, molybdenum and zinc concentrations were measured in the liver and kidneys from each horse. Arsenic and lead were not detected in any tissues. Liver heavy metal concentrations were not related to the injury type. Kidney iron concentrations were significantly (P < 0.05) higher in horses with ligament ruptures and in horses with fractured sesamoid, carpus or metacarpus/metatarsus bones. Live...
Metacarpophalangeal joint synovial pad fibrotic proliferation in 63 horses. Medical records, radiographs, and sonograms of 63 horses with metacarpophalangeal joint synovial pad proliferation were examined retrospectively. All horses had lameness, joint effusion, or both signs associated with one or both metacarpophalangeal joints. Bony remodeling and concavity of the distodorsal aspect of the third metacarpal bone (Mc3) just proximal to the metacarpal condyles was identified by radiography in 71 joints (93%); 24 joints (32%) had radiographic evidence of a chip fracture located at the proximal dorsal aspect of the proximal phalanx. Fifty-four joints (71%) were examined...
[Expert opinions about a case of injury which by a failure of a restraining device caused a life-threatening injury to a breeding stallion]. A stallion got fatal injuries by kicks of a maiden mare because a so called "panic hook" untied spontaneously. The use of such hooks to secure mares during mating should therefore not be recommended.
Horseback-riding-associated traumatic brain injuries–Oklahoma, 1992-1994. Each year, traumatic brain injury (TBI) is associated with 52,000 deaths and accounts for one third of all injury deaths in the United States; in addition approximately 80,000 persons who survive TBI incur some loss of function, residual disability, and increased medical-care needs because of these injuries. Major causes of TBI are motor-vehicle crashes, falls, assaults, and sports and recreational activities. During 1992-1993 in Oklahoma, horseback riding was the leading cause of sports-related TBI. To further characterize horseback-riding-associated TBIs, the Oklahoma State Department of Hea...
Tendon strain in the forelimbs as a function of gait and ground characteristics and in vitro limb loading in ponies. Strains in the tendons of the m. flexor digitalis superficialis (superficial digital flexor, SDFT) and m. flexor digitalis profundus (deep digital flexor, DDFT) tendons, the accessory ligament of the deep digital flexor muscle (inferior check ligament, ICL) and the m. interosseus medius (suspensory ligament, SL) of 5 ponies were recorded at the walk and trot using mercury-in-silastic strain gauges (MISS), on a hard surface (brick pavement) and on sand. The horses were shod with normal, flat shoes. On pavement, strain in the SDFT, DDFT and SL increased significantly from the walk (2.19%, 1.15% ...
Accidents with horses: what has changed in 20 years? Horse riding is a dangerous pastime with more accidents occurring per hour than during motor-cycling. Since a prospective survey of horse-related injuries conducted at a major centre in 1971-1972, equestrian groups and the medical profession have encouraged improvements in training and protective riding wear. By conducting a similar study at the same centre 20 years later we hoped to assess the effects of these measures on the pattern of injuries resulting from contact with horses. Patient and injury details were recorded prospectively for all those presenting to the Accident Service at Oxford...
[Luxation of the shoulder joint in a horse. A case report]. Etiology, diagnosis and therapy of the luxation of the shoulder joint in the horse are described. The traumatic luxation is diagnosed by physical examination and radiography. Without complicating changings (like fractures) and in case of early correction the prognosis is good.
