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.
[The horse as an athlete: an animal model of choice for sports medicine: sonographic studies of joint disorders]. Equine diagnostic sonography was initially used for the diagnosis and documentation of tendon injuries. Since 1990, this technique, along with radiography, has become an indispensable imaging procedure for the diagnosis of equine joint injuries. Sonography provides precise diagnostic information on the synovial membrane and fluid, the articular cartilage, subchondral bone and joint margins, the ligaments and menisci, and the anatomical structures involved in periarticular swelling or enlargement. Improvements in ultrasound machines and better superficial and deep image resolution allow us to e...
Osteochondral injury increases type II collagen degradation products (C2C) in synovial fluid of Thoroughbred racehorses. To investigate the effects of exercise and osteochondral (OC) injury on type II collagen degradation products (collagenase cleavage neoepitope commercially known as C2C) in synovial fluid (SF) from Thoroughbred (TB) racehorses and to compare these results with radiographic and arthroscopic scores of severity of joint injury. Methods: Metacarpophalangeal/metatarsophalangeal (MCP/MTP) and carpal SF was obtained from (1) 20 normal rested horses, (2) the same horses after 5 to 6 months of race training, and (3) 27 horses with OC injury from racing. For group 3, radiographic and arthroscopic scores...

[Frequency of diseases and injuries in the Swiss horse population]. Through a written questionnaire, which was sent to a representatively distributed and randomly selected sample of Swiss horse owners, data of 2912 horses and ponies were acquired to extrapolate prevalence data of health disorders. General questions about the horse and associated factors of housing and use, as well as questions about the current health status and the occurrence of diseases and injuries had been asked. 718 horses (24.7% of the sample) had been examined by a veterinarian within the 12 months prior to the survey. Orthopaedic and traumatic disorders (41.5%) had the largest proporti...
Equestrian-related injuries: implications for treatment in plastic surgery. Equestrian activities have always been popular in the United States. As safety guidelines have become more stringent, horse-related injuries have diminished by 40 percent over the past 20 years. Although perhaps less critical than in the past, injuries to equestrians most frequently involve the face, upper extremity, and lower extremity and are commonly evaluated by the plastic surgeon. The purpose of this study was to determine the characteristics of these equestrian-related injuries. Methods: The National Electronic Injury Surveillance System database is a stratified probability sample of ho...
Factors affecting outcome of extensor tendon lacerations in the distal limb of horses. A retrospective study of 156 cases (1994-2003).

Results: The main risks identified were drowning; farm...
Mesenchymal stem cell therapy for equine tendinopathy. Optimal management of tendon overuse injuries in equine and human athletes should avoid the formation of excessive scar tissue, regenerate normal tendon matrix, and reduce re-injury rates. We hypothesized that the implantation of marrow-derived stromal stem cells (BM-MSCs), in far greater numbers than are present normally within tendon tissue, would synthesize a matrix more closely resembling tendon matrix than scar tissue, and hence increase the capacity to return to performance successfully. This article reviews the technique used clinically in the horse and the current outcome data for hors...
Effect of adipose-derived nucleated cell fractions on tendon repair in horses with collagenase-induced tendinitis. To assess the potential of adipose-derived nucleated cell (ADNC) fractions to improve tendon repair in horses with collagenase-induced tendinitis. Methods: 8 horses. Methods: Collagenase was used to induce tendinitis in the superficial digital flexor tendon of 1 forelimb in each horse. Four horses were treated by injection of autogenous ADNC fractions, and 4 control horses were injected with PBS solution. Healing was compared by weekly ultrasonographic evaluation. Horses were euthanatized at 6 weeks. Gross and histologic evaluation of tendon structure, fiber alignment, and collagen typing were...
Equine-related facial fractures. Horseback riding is a common recreational activity that can cause injuries to both mounted and dismounted participants.

Patients presenting over an 11-year period from 1996 to 2006 with equine-related maxillofacial fractures were identified through the trauma database. The extent of the injuries, surgical treatment and follow-up details were documented. 45 patients were identified, with an increasing incidence over the study period. 69% were male and 31% female. 31% of patients ...
Influence of muscle-tendon wrapping on calculations of joint reaction forces in the equine distal forelimb. The equine distal forelimb is a common location of injuries related to mechanical overload. In this study, a two-dimensional model of the musculoskeletal system of the region was developed and applied to kinematic and kinetic data from walking and trotting horses. The forces in major tendons and joint reaction forces were calculated. The components of the joint reaction forces caused by wrapping of tendons around sesamoid bones were found to be of similar magnitude to the reaction forces between the long bones at each joint. This finding highlighted the importance of taking into account muscle...
The collateral ligaments of the distal interphalangeal joint: magnetic resonance imaging and post mortem observations in 25 lame and 12 control horses. Magnetic resonance imaging (MRI) is used with increasing frequency to diagnose injuries of the collateral ligaments (CLs) of the distal interphalangeal (DIP) joint, but the results have not been verified by histology and the mechanism of injury is poorly understood.

The pathobiology of exercise-induced superficial digital flexor tendon injury in Thoroughbred racehorses. Despite the high incidence of superficial digital flexor tendon (SDFT) injury in racehorses, the pathobiology of the condition is not clearly defined. The SDFT improves locomotor efficiency by storing elastic energy, but as a result it has low mechanical safety margins. As with the Achilles tendon in humans, rupture during athletic activity often follows accumulation of exercise and age-induced degenerative change that is not repaired by tenocytes. There is limited understanding of tenocyte biology and pathology, including responses to high mechanical strains and core temperatures during exerc...

Conservative treatment of a comminuted cervical fracture in a racehorse. The 'classical' or 'Hangman' neck fracture involves the odontoid peg (process) of the second cervical vertebra (C2), and is described as an axial, dens or odontoid peg fracture in both the veterinary and human literature. Possible surgical treatment in both foals and adult horses requires a technique that allows decompression, anatomical alignment and stabilisation of the odontoid fracture. A limited number of surgical cases in foals have been reported in literature, but never in an adult horse. A mature Irish Thoroughbred racehorse was diagnosed with a type 2a odontoid peg fracture. Clinical ...
Articular fetlock injuries in exercising horses. Articular injuries to the fetlock joint can be categorized as injuries to the soft tissues (synovium, ligaments, cartilage) or bone (third metacarpus/metatarsus, first phalanx, proximal sesamoids). This article focuses on the traumatic injuries to the cartilage and bone from anatomic, functional, and pathophysiological perspectives. An understanding of fetlock motion and loading will assist clinicians in the diagnosis, treatment, and, most importantly, prevention of fetlock injury in working horses.
The effect of early training and the adaptation and conditioning of skeletal tissues. Horses as equine athletes must be conditioned and trained to optimize the whole animal for the particular type of athletic activity. An extremely high proportion of all injuries in the equine athlete in general, and in the racehorse in particular, are associated with the skeletal system, many of which are believed to arise from a mismatch between the prevailing exercise levels and adaptation. To maximize performance, yet minimize injury, it is important to understand and apply the principles of functional adaptation of the component tissues of the skeletal system (bone, cartilage, tendons, and...
Regenerative medicine for tendinous and ligamentous injuries of sport horses. After tendon injury, the scar tissue that replaces the damaged tendon results in a substantial risk for reinjury. The goal of regenerative therapies is to restore normal structural architecture and biomechanical function to an injured tissue. Successful restoration processes for any tissue are thought to recapitulate those of development, in which there are spatial and temporal interactions between scaffold, growth factors, and cell populations.
The California Postmortem Program: leading the way. The California Postmortem Program studies disease surveillance, discovers new causes of death, and develops new diagnostic methods for disease detection. It also informs directions for research focused on elucidating the etiopathogenesis of, and risk factors for, catastrophic fractures and other causes of death. Because most fatal injuries seem to be the acute culmination of a more chronic process, intervention and prevention of injuries is possible with enhanced knowledge of the etiopathogenesis of injuries and risk factors for injuries. These advances also would facilitate development of man...
Future tools for early diagnosis and monitoring of musculoskeletal injury: biomarkers and CT. This article provides an overview of two relatively new techniques that can be used for the early detection of musculoskeletal injury: biochemical markers and CT. The emphasis in the biomarker section is on the early detection of joint disorders because these are most important clinically and most of the research has been conducted in this area. In the section on CT, bone is the target tissue.
Musculoskeletal injuries in nonracing quarter horses. Quarter horses used for western performance competitions commonly sustain a variety of musculoskeletal injuries. It is important for the veterinarian to have an understanding of some of the breed characteristics and the nature of the competitions in which individual horses are being used so as to diagnose, treat, and prevent injury as effectively as possible.
Adaptation strategies of horses with lameness. The skill to diagnose lameness in horses is paramount for every equine practitioner. Early recognition of locomotor deficiencies plays a central role in sports medicine management, preventing deterioration of the disease or catastrophic injuries. Horses use characteristic compensatory movements of specific body parts to decrease loading of the affected limb. This article describes the underlying changes in intra- and interlimb coordination and the resulting load redistribution between the limbs. This enables the practitioner to better understand the changes in movement associated with lameness...
