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.
Musculoskeletal Burden in German Equestrians: Hip-Specific Symptoms and Risk Factors. Equestrian sport is a major component of German athletics, with broad recreational participation and a strong competitive sector. In 2019, about 2.32 million people identified as active riders, and more than 60,000 competitional licences were issued in 2021, reflecting substantial competitive engagement across the Olympic disciplines and national performance levels. Hip pain is a frequent and clinically relevant complaint among athletes and can stem from structural, degenerative, or overuse-related causes. In riding, the hip joint is crucial for transmitting forces and coordinating rider-horse...
A retrospective study of morbidity and mortality in captive Przewalski’s horses (Equus przewalskii) between 1973 and 2021. Przewalski's horses (Equus przewalskii) were declared extinct in the wild in 1996, but reintroduction programmes initiated in 1997 have enabled the re-establishment of free-ranging populations. The maintenance of healthy captive populations remains essential to support these conservation efforts, yet systematic pathological investigations in captive Przewalski's horses are lacking. This study provides the first necropsy-based overview of morbidity and mortality in a captive European population. Pathology reports from 64 horses examined between 1973 and 2021 were reviewed retrospectively. Acros...
Pathology of sudden death in racehorses: a review. Sudden death (SD) is the second most important syndrome associated with death in racehorses. The cause of SD in a large number of horses remains undetermined, and, in many of these cases, causes are not found by gross or microscopic postmortem examinations. Among the known causes of SD are traumatic injuries, including fractures of skull, neck, and pelvis; intoxications (e.g., anticoagulant rodenticides); and others. For many cases of SD in which no significant lesions are found, heart failure, probably associated with arrhythmias, is suspected. Precise phenotypic characterization of SD in hor...
Evaluation of doppler indexes of the lateral palmar digital artery in lame sport horses. Although lateral palmar digital artery (LPDA) flow velocity does not differ between forelimbs, horses with lameness typically reduce loading of the affected limb during the weight-bearing phase. This study aimed to assess whether Pulsed-Wave (PW) Doppler indices of the (LPDA) blood flow differ between the two forelimbs in horses with unilateral forelimb lameness, and whether these differences correlate with lameness severity. Twenty-seven lame and 15 healthy horses were enrolled. All Doppler ultrasonographic examinations were performed by a single operator, blinded to both the presence or abse...
Outcomes and racing performance in thoroughbreds following a long-term injury sustained during a jump race in Great Britain.

The impact of barefoot racing in young Swedish trotters on career length. In several European countries, racing without shoes, i.e., barefoot, is a common strategy in trotting races to improve the speed of the horse. Why some trotters can race barefoot without damage to the hoof from excessive wear and others cannot, has been shown to partly be explained by differences in hoof composition. In particular, durable hind hooves are believed to be important to sustain racing without shoes. Also, variation in the proportion of the races the horse races with barefoot hind hooves, has been shown to be affected by genetic differences in Swedish Standardbred trotters (SB) and...
