Topic:Fractures
Fractures in horses refer to the disruption in the continuity of a bone, often resulting from trauma, excessive stress, or pathological conditions. These injuries can vary in severity, from simple, non-displaced fractures to complex, comminuted fractures involving multiple bone fragments. Fractures can affect any bone in a horse's body, but they are most commonly observed in the limbs due to the high mechanical loads these structures endure. Diagnosis typically involves clinical examination and imaging techniques such as radiography or ultrasound to assess the extent and nature of the fracture. Treatment strategies depend on the type and location of the fracture and may include rest, immobilization, surgical intervention, or a combination of these approaches. This page aggregates peer-reviewed research and scholarly articles focusing on the etiology, diagnosis, management, and outcomes of fractures in horses, providing insights into current veterinary practices and advancements in equine orthopedic care.
Analysis of horse race videos to identify intra-race risk factors for fatal distal limb fracture. The objective of this study was to identify risk factors, during racing, associated with imminent fatal distal limb fracture in Thoroughbreds. One hundred and nine cases of fatal distal limb fracture were identified from all 59 UK racecourses over a 2-year period (February 1999-January 2001). Three uninjured control horses were randomly selected from the same race as the case horse. Videos of races in which fractures occurred were viewed using a defined protocol. Fractures in flat races occurred at any time during the race, whereas 74% (45/61) of cases in national hunt type races occurred in t...
A case-control study of factors associated with pelvic and tibial stress fractures in Thoroughbred racehorses in training in the UK. Few epidemiological studies have investigated risk factors for musculoskeletal injury occurring in Thoroughbred racehorses during training, although it is the major cause of wastage in the racing industry. We recently conducted a large-scale epidemiological study to estimate the incidence of fracture in racehorses in training in the UK and to identify associated risk factors. Thirteen racehorse trainers provided data on horses in their care, with daily recording of training information and provision of details on any fractures incurred. Data were collected for 2 years, including two consecutiv...
Catastrophic fracture of the lateral condyle of the third metacarpus/metatarsus in UK racehorses – fracture descriptions and pre-existing pathology. The characteristics of, and pre-existing pathology associated with 75 cases of fatal lateral condylar fracture sustained by Thoroughbreds while racing in the UK were described. Cases were identified from 220 cases of fatal distal limb fracture submitted as part of studies designed to identify risk factors for all fatal distal limb fractures. Fractures were most common in hurdle races and affected the right forelimb twice as often as the left forelimb. Fracture dimensions were similar to previous reports, however there was a much greater prevalence of articular and diaphyseal comminution and of...

Comminuted fracture of the distal sesamoid bone and distal rupture of the deep digital flexor tendon. A 10-year-old show jumper was evaluated for an acute severe lameness (grade 4 of 5) of the right foreleg. During weight bearing, the toe of the affected limb rotated dorsally suggesting rupture of the deep digital flexor tendon (DDFT). Upon radiographic examination of the hoof, a severe erosion at the flexor surface and a parasagittal fracture of the distal sesamoid bone were found. Ultrasonographic examination confirmed rupture of the DDFT. These findings were confirmed on post-mortem examination. Prior to the acute lameness, the horse was treated with corticosteroid injections into the podot...
[Conservative treatment of open incomplete radial fracture in an adult horse]. A non-displaced radialfracture of a horse was,diagnosed. The horse had an open fracture resulting from external trauma. A diagnosis was made on radiographs taken 48h after trauma. The horse was treated conservatively by box rest and Robert-Jones bandages. After 7 days the wound was opened to let the wound drainage necrotic material and small sequesters and was washed every other day. After 7 weeks, radiographs showed complete consolidation. Four months after the injury the horse was back to work at his former level and is still working two years after the incident.

Management of neck and head injuries. The horse, a flight animal that is used extensively by man, frequently receives injuries to its neck or head that result mostly from its management and handling. Better facilities, training of the horse, and horsemanship skills of the handler could prevent many of these injuries. Because many body systems can be involved, with potentially major consequences regarding health, performance, and appearance, early recognition of trauma and competent treatment are crucial. Progress has been made in the treatment of some tracheal and esophageal injuries. Severe tracheal trauma and rupture of the esop...
Radiographic and pathologic characterization of lateral palmar intercarpal ligament avulsion fractures in the horse. In this study, the radiographic and histologic appearance of lateral palmar intercarpal ligament (LPICL) avulsion in the horse was characterized. Thirty-seven horses with radiographic evidence of avulsion fragments originating from the medial palmar aspect of the ulnar carpal bone were examined. The dorsolateral to palmaromedial projection was useful for evaluating the size and shape of the avulsed bone fragment, and the dorsopalmar projection added information on the relative proximity of the fragment to its fracture bed. Radiographic features that differentiated LPICL avulsion from subchondr...
