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.
Reproductive emergencies in the stallion. Topics addressed in this article include complications of castration, scrotal and inguinal hernias, torsion of the spermatic cord, traumatic injuries to the external genitalia, and posthumous collection of spermatozoa. A concise overview of the clinical management of emergency cases is provided.
Soft tissue emergency in adult horses. Equine practitioners are frequently called to attend to soft tissue injuries. The majority of these cases are routine and straightforward; however, a certain percentage may present as a life-threatening situation with potentially serious complications. Client communication, adequate preparation, patient stabilization, accurate injury assessment and appropriate wound preparation are key factors to expedite recovery and achieve a favorable outcome. Understanding the limitations of field therapy and deciding when to transport the case to a clinic or referral center plays an important role in the ...
[Equestrian accidents in children and adolescents]. The rate of pediatric equestrian injuries is relatively low, but the severity of injuries is greater than in many other pediatric sport activities. In a 4-year period the charts of 109 patients up through the age of 15 years, who were admitted for equestrian-related injuries were reviewed. Falls from horses are the most frequent cause of injuries and responsible for their anatomic localization and type of injury. In our study the upper extremity was the most common (38%) area injured and head injuries comprised the second largest group with 36%. Forty percent of all injuries were fractures, 72...
Management of orthopedic emergencies. Initial management of injuries includes safely gaining control of the animal and assessing and treating systemic shock. If hemorrhage is life threatening, it must be controlled. If the limb is nonfunctional it should be stabilized. Any open orthopedic injury should be treated by cleaning the tissues, protecting the exposed tissues, and administering systemic antibiotics. A commercial splint is available (Equine Regular Leg Saver Splint, Kimzey Welding Works, Woodland, CA) that can immobilize and relieve weightbearing for cases of phalangeal fracture, flexor tendon rupture, fetlock breakdown, a...
Observations on the anatomy and pathology of the palmar intercarpal ligaments in the middle carpal joints of thoroughbred racehorses. Ten carpi from juvenile Thoroughbred horses were dissected in detail to record the anatomy of the palmar intercarpal ligaments (PICLs). These were found not to be substantially attached to the palmar carpal ligament. The lateral PICL was sited at the convergence of the palmar aspects of the third, fourth, intermediate and ulnar carpal bones and aligned predominantly in a proximodistal direction. The medial PICL had a large origin distally on the lateral aspect of the radial carpal bone (Cr) and attached to third (C3) and second (C2) carpal bones with apparently separate fibre orientations. Fib...
Three-dimensional sonographic imaging of the equine superficial digital flexor tendon. In a feasability study, a technique for constructing 3-dimensional sonographic images of the superficial digital flexor tendon (SDFT) was established in 6 clinically normal horses and applied to 7 horses with injured SDFT. Two-dimensional B-mode sonographic images were recorded on videotape as the sonographic transducer was manually moved along the palmar aspect of the metacarpal region. Selected videofields were digitized, and 3-dimensional images were constructed, using a computer work station and dedicated software program. The 3-dimensional images were of high quality and presented qualita...
Comparison of the cranial and a new lateral approach to the femoropatellar joint for aspiration and injection in horses. The genual joint in horses is complex, making synovial fluid aspiration and injection of the femoropatellar joint difficult. Horses commonly have signs of resentment to needle penetration at this site. We compared the safety and efficacy of a new technique, using a lateral approach to the femoropatellar joint, with that of the standard cranial approach in 12 horses. A significantly greater amount of fluid was obtained with the lateral approach (2.0 +/- 0.5 ml, mean +/- SEM) than with the cranial approach (0.9 +/- 0.2 ml). Significant differences were not observed in color, nucleated cell count...
Stringhalt secondary to trauma to the dorsoproximal region of the metatarsus in horses: 10 cases (1986-1991). A review of medical records was used to identify 10 horses in which stringhalt developed subsequent to trauma to the dorsal metatarsus. Six horses developed stringhalt within 3 months after injury, 3 horses developed stringhalt > 3 months after injury, and time from injury to stringhalt was unknown for 1 horse. Horses were treated with exercise, including daily hand-walking with pasture turnout, followed by lunging; or surgically, using lateral digital extensor myotenectomy. Of the horses treated with exercise, 1 had resolution of stringhalt, 2 improved but had residual stringhalt, and 1 ha...
The anatomic features of the normal tarsus of the live horse as perceived by the sense of sight. A description is given of 75 features present in the normal tarsus of the standing horse which are apparent due to visible skin contours overlying them. Depending on whether or not the pelvic limb is supporting full weight or resting, some contours alter their configuration. Therefore the contour of each underlying feature is described separately for each stance of the limb. It is considered that visual inspection and identification of the apparent superficial features of the normal equine tarsus form the basis of orientation and clinical inspection. Furthermore, these features provide referen...
Horseback riding injuries among children and young adults. Horseback riding injuries are responsible for an estimated 2300 hospital admissions annually among persons younger than 25 years of age in the United States, but injury rates, patterns of injury, and risk factors for this population have not been well studied. Methods: Study participants were selected from a list provided by a national mail-order company that sells riding equipment. A total of 557 persons younger than 25 years of age who rode horses at least six times a year completed survey questionnaires. Results: Among the study participants, 34 (6.1%) had been hospitalized at least once be...
Diagnostic techniques for identification and documentation of tendon and ligament injuries. Conventional clinical examination remains of medical and economic value for diagnosis of soft tissue injuries in the equine athlete. This procedure requires concentration and rigor to establish the diagnosis, and, if possible, some experience to better evaluate the prognosis. None of the new imaging techniques can replace the physical examination, but each may provide additional information. These sophisticated methods are bringing considerable progress in the knowledge of locomotor injuries in the horse and a tremendous improvement in our ability to diagnose precisely lamenesses and limitatio...
The pathobiology and repair of tendon and ligament injury. Injury of the collagenous structures comprising tendons and ligaments, either from acute trauma or from repetitive strain lesions, results in protracted periods of disability. The resolution of such injuries often fails to restore the normal morphologic and functional characteristics of the structure and, therefore, either compromises the future performance of the individual or predisposes to an increased risk of recurrent injury.
Superior check ligament desmotomy for treatment of superficial digital flexor tendonitis in thoroughbred and standardbred horses. Bilateral superior check ligament desmotomy was performed on 31 Thoroughbred and 17 Standardbred horses as the sole method of treatment for superficial digital flexor tendonitis. Horses resumed racing between 6 and 19 months after surgery. Horses that were able to compete in 5 or more races without injury to the tendon again were considered to have had a successful return to racing. Twenty-five Thoroughbreds were suitable for later study and 13 of these (52%) raced on 5 or more occasions. Fifteen Standardbreds were suitable for later study and 10 of these (66%) raced on 5 or more occasions. Wi...
Practical management of superficial digital flexor tendinitis in the performance horse. The authors of this section represent a broad range of practice experience with horses that perform in rigorous and varied sport competitions. Each breed and performance application represent unique challenges of diagnosis and uncompromising demands on rehabilitated tendon injuries. This article will serve to guide, stimulate, and encourage veterinarians to apply scientific criteria to the evaluation of tendinitis therapy in the years to come so that we can arrive at a more valid consensus as to the "best" means of tendon and ligament injury management.
Treatment of superficial digital flexor tendinitis. This article reviews the research and clinical findings relevant to the treatment of acute tendinitis in the horse. The goals of treatment are to reduce inflammation, minimize scar tissue formation, and promote restoration of normal tendon function. A wide variety of treatments have and still are being used to treat tendinitis, which indicates that there is no uniformly successful way to return a horse to full athletic function after injury. Therapy depends on the severity of tendinitis and duration of injury and can be divided into treatment during the inflammatory, repair, and maturation pha...
In vitro mechanical properties and failure mode of the equine (pony) cranial cruciate ligament. In vitro failure modes and mechanical properties of the equine cranial cruciate ligament (CCL) were evaluated in 15 stifle joints from 10 ponies. Ponies were from 3 to 25 years of age and weighed from 122 to 208 kg. Femur-CCL-tibia specimens were mounted in 48 degrees of flexion, distracted until a 500-g tensile preload was achieved, and then tested by tensile loading to failure. Specimens failed by complete midsubstance CCL rupture (n = 9), combined tibial insertion avulsion fracture and midsubstance CCL rupture (n = 4), and combined femoral origin avulsion fracture and midsubstance CCL ruptu...
Causes of death in racehorses over a 2 year period. Necropsies were performed on 496 horses that had a fatal injury or illness at a California racetrack during the period February 20th 1990 to March 1st 1992. The primary cause of death was categorised by breed, activity at time of injury or illness and organ system affected. Most of the submissions were Thoroughbred horses (432) and Quarter Horses (46). Most of the injuries occurred while racing (42%) and in training sessions (39%); with fewer non-exercise (12%) and accident (7%) related injuries or illnesses. Musculoskeletal injuries accounted for 83% of the Thoroughbred and 80% of the Quarter...
Attempts to modify reperfusion injury of equine jejunal mucosa using dimethylsulfoxide, allopurinol, and intraluminal oxygen. This study compared the severity of ischemic injury to the equine jejunal mucosa caused by arteriovenous obstruction (AVO) or venous obstruction (VO) with that caused by reperfusion after ischemia. The degree of mucosal damage and regeneration was scored according to a modified version of an established light microscopic classification for ischemic injury. Biopsy specimens taken after 3 and 4 hours of obstruction, and after 3 hours of obstruction and 1 hour of reperfusion, were compared. There were no changes in the severity of mucosal injury (characterized by epithelial sloughing, loss of vil...
Carpal conformation in relation to carpal chip fracture. An objective radiological method of assessing the degree to which horses are conformationally 'back at the knee' (hyper-extended) is described. The effects on the measurements of variations in the direction of the incident X-ray beam and variations in weight bearing by the horse were assessed. A change from a lateromedial projection towards a plamaro-lateral-dorsomedial oblique projection consistently tended to reduce the observed degree of hyperextension of the carpus. Raising the contralateral limb to increase the load on the carpus had little effect on the measurements. The carpi of 21 thor...
Repair of fractures of the distal aspect of the radius in two horses. Fractures of the distal radius in two horses were repaired by open reduction and interfragmentary compression using screws placed in a lag fashion. One horse had a complete oblique fracture of the medial aspect of the epiphysis of the distal radius and was sound for riding 32 months after surgery. The other horse had an open spiral comminuted fracture with medial displacement of the distal radial fragment. Laminitis developed in the contralateral limb and this horse was euthanatized 5 weeks after surgery.
Avulsion of the origin of the peroneus tertius tendon in a foal. A 3-month-old foal was examined because of lameness and fracture of the left lateral trochlear ridge of the femur. Arthroscopy of the left femoropatellar joint was elected. After induction of general anesthesia and placement of the foal in dorsal recumbency, it was noticed that the left hind limb was extended at the tibiotarsal joint and flexed at the femorotibial joint. Avulsion fracture at the origin of the peroneus tertius tendon was diagnosed. Fracture fragments were excised. The horse had mild left hind limb lameness at the time of follow-up evaluation 1 year after discharge.
Ultrasonographic evaluation and long-term follow-up of flexor tendonitis/desmitis in the metacarpal/metatarsal region in Dutch warmblood horses and standardbred racehorses. Over a 2 year-period, the ultrasonographic localization and distribution of flexor tendinous and ligamentous injuries, the long-term follow-up, and the outcome were studied in 101 Dutch Warmblood horses (DW) with a mean age of 8.7 years and in 71 Standardbred racehorses (ST) with a mean age of 5.2 years. The ratio between forelimb and hind limb flexor tendonitis/desmitis in the DW-group was 4:1 and in the ST-group group 4:3. In the DW-group, tendonitis/desmitis of the suspensory ligament (32%), the superficial digital flexor tendon (29%), the distal carpal check ligament (17%) of the forelimb ...
Equestrian injuries: a five-year review. A retrospective chart review was conducted to define the demographic and injury patterns of patients presenting to the emergency department (ED). The setting is a rural/small urban tertiary care center with approximately 40,000 visits per year. All patients presenting to the ED from January 1986 through December 1990 with equestrian-related injuries were enrolled in the study. Measurements included age, sex, mechanism of injury, injury or injuries diagnosed, admission to the hospital, morbidity, and mortality. A total of 142 patients met the inclusion criteria. The majority of injuries occurre...
Fracture of the wing of the ilium, adjacent to the sacroiliac joint, in thoroughbred racehorses. During a two year period, sagittal fractures of the wing of the ilium were diagnosed in 10 Thoroughbred horses. All were spontaneous fractures sustained during normal exercise in training and racing, with no history of inciting trauma. When ultrasound scans of the surface of the pelvis were performed, the fracture was clearly visible as a discontinuity of the sacral wing of the ilium. In 3 horses, an irregular contour suggestive of periosteal callus was seen in the vicinity of the acute fracture. All horses examined by gamma scintigraphy had a focal increase in uptake of isotope just lateral t...
Prevalence of, and factors associated with, musculoskeletal racing injuries of thoroughbreds. All horses diagnosed by a commission veterinarian of the Kentucky Racing Commission as having sustained a musculoskeletal injury, defined as an obvious change in soundness immediately before, during, or after a race held between Jan 1, 1992 and May 31, 1993 were included in a study to determine the prevalence of and factors associated with racing injuries involving the musculoskeletal system of horses competing at 4 Thoroughbred racetracks in Kentucky. During the 17-month study, there were 35,484 racing starts among 7,649 horses in 3,824 official Kentucky Racing Commission races. During this p...
Scintigraphic and ultrasonographic diagnosis of soft tissue injury in a thoroughbred horse. A 2.5-year-old female Thoroughbred horse was referred to the veterinary teaching hospital for right front limb lameness of 1 year duration. Physical examination and diagnostic nerve blocks failed to localize the origin of the lameness. Scintigraphy with 99mTc-MDP suggested increased radionuclide uptake in the palmar metacarpal soft tissues of the right front limb. Ultrasonographic examination revealed hypoechoic lesions in the superficial digital flexor tendon and the suspensory ligament, suggesting tendinitis and desmitis. Combined imaging modalities improved detection and characterization of...
Helmets and horseback riders. To determine patterns of helmet use and attitudes toward helmets among horseback riders, we analyzed a subset of data (n = 1,834) from a cross-sectional mail survey of horseback riders conducted from July to December 1991. Riders were randomly selected from the mailing list of a national mail-order company that sells horseback-riding equipment. Of 900 English-style riders, 517 (57.5%) wore helmets on their last ride, compared with only 81 of 684 (11.8%) Western-style riders. Among 546 riders who did not own helmets, their most commonly cited reasons included believing that helmets were unneces...
Is horse riding a dangerous recreation for young girls? A study at emergency departments of Lahti City Hospital and Päijat-Häme Central Hospital, Lahti. Horse-related injuries form a notable part of sports and leisure time accidents. 54% of the injured were female riders under the age of 20 years. The most serious injuries were upper extremity ones. Over one third of the riders had suffered previously from horse-related injuries.
