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.

Meredith L, Thomson R, Ekman R, Kovaceva J, Ekbrand H, Bálint A.Horse riding is a popular activity but has also been found to lead to many injuries and even fatalities. No reduction in the numbers of those being admitted to hospital for equestrian-related injuries have been seen in Sweden in recent years. The aim of this work was to examine injuries, fatalities, and predictors of fatalities in equestrian-related activities and to investigate the cost of these injuries to the public health system. Methods: The study is a retrospective analysis of hospital data. Methods: National Swedish hospital and mortality registers were retrospectively examined, inclusi...
Rogers CW, Dittmer KE.In mammals, play behaviour appears innate and, because of this, may provide insight into the frequency and intensity of load that is required to stimulate positive musculoskeletal development. The objective of this review was to explore the interaction between play and tissue (bone) development at a molecular through to whole-animal level, with specific focus on the horse as a model. The basis of our understanding of the response of bone to loading is the mechanostat theorem. This assumes that at a tissue level, bone attempts to keep localised strain within the physiological range of 1500-2500...
Asa N, Newton A, Sullivan L, Shi J, Wheeler K, Smith GA, Yang J.Despite inherit dangers of horseback riding (HBR), research on HBR-related injuries is sparse. This study used both quantitative and qualitative methods to (1) examine HBR-related injuries treated in emergency departments (EDs) and associated risk factors and (2) explore HBR-related injury experiences and recommendations for prevention strategies from the perspective of riders. We retrospectively analyzed data from the Nationwide Emergency Department Sample (NEDS), identifying HBR-related ED visits between 2010 and 2014. Additionally, we conducted 10 phone interviews with active horseback ride...
Fraser BS, Bladon BM.Lacerations to the digital flexor tendon sheath (DFTS) are a common injury in the horse, but little information is available in the literature regarding prognostic indicators. Objective: To ascertain whether laceration of the DFTS carried a better prognosis if treated by tenoscopic lavage, debridement and repair within 36 h of the original injury. Methods: A retrospective analysis of 39 horses treated surgically for lacerations to the DFTS was performed over a 3 year period. The injury-to-surgery interval was recorded as <36 or >36 h. The structures damaged by the injury were also recorded, as...
Quiney L, Murray R, Dyson S.This case report describes the successful management of two horses with medial carpal collateral ligament injury. This is a rare cause of forelimb lameness and existing reports indicate a poor prognosis for return to athletic function with conservative management. Both horses were treated with a combination of box rest with controlled exercise and high-intensity laser therapy (HILT). Both horses returned to previous athletic function, one at Grand Prix level dressage and one at Novice level eventing. With appropriate management, the prognosis for carpal collateral ligament injury may be good. ...
