Reasons for performing study: Lameness is highly prevalent in working horses, but published reports on the associated pathological abnormalities are lacking. With over 42 million horses in developing countries and the majority used for work, lameness has major welfare implications.

Objectives: To describe the range and prevalence of pathological abnormalities associated with lameness in working horses.

Reasons for performing study: Warmblood horse studbooks aim to breed horses with a conformation that will enable elite future sports performance, but reduce the risk of early retirement due to lameness. Negative conformational traits, such as asymmetrical or 'uneven' forefeet may possibly shorten the career of sporthorses.

Objectives: To investigate the significance of foot conformation at young age to duration of the career of sporthorses.

Reasons for performing study: Warmblood horse studbooks aim to breed horses with a conformation that will enable elite future performance, but reduce the risk of injuries and lameness. Negative conformational traits, such as asymmetrical or 'uneven' forefeet would possibly diminish performance.

Objectives: To assess the prevalence and heritability of uneven feet and its genetic relationship to other conformation traits as well as to sporting performance later in life in Warmblood riding horses.

Surgical site infections are an inherent risk in orthopaedic surgery and many of the infections that develop are likely to be non-preventable. However, a variety of measures can be undertaken to reduce the risk and impact of surgical site infections. The development and implementation of an infection control program, including surgical site infection surveillance, can be an important tool for patient management.

The aim of this article is to review current knowledge of kinetic variables of the hoof-track interaction and track properties relevant to the objective of minimizing injuries to horses at racing tracks. In each phase of the stance-primary impact, secondary impact, support, and breakover, the hoof experiences different combinations of force and acceleration. The role of each combination, and of measured track properties, in causing catastrophic and chronic injuries to the limbs of racing horses is unknown.

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.

Preview:This article describes the development of epidemiologic analyses of racetrack injury in racehorses. The risk or rate of fatal and nonfatal injury in racing and training around the world is examined. The focus is on the importance of global collaboration and the identification of modifiable risk factors. In particular, exercise-related risk factors for injury are evaluated and the potential impact of interventions discussed.

Abstract:Reasons for performing study: No data exist on the intensity of exercise required or on possible harmful effects of increasing exercise in foals over the natural level when free at pasture.  Objectives: To investigate whether an increase in workload over free pasture exercise in the period from directly after birth to the start of training is tolerated by Thoroughbred (TB) foals without increasing injury rate or producing other undesired side effects.

Abstract:Reasons for performing study: No data exist on the effects of conditioning exercise at foal age on workload and subsequent clinical injury rate during their 2- and 3-year-old racing careers.  Objectives: To investigate the effects of subjecting TB foals to conditioning exercise prior to the start of race training on: the workload required to reach a level of fitness sufficient to compete; and the prevalence of orthopaedic injury during the first 2 seasons of their racing careers.
