Traumatology

Penetrating injuries to the foot are potentially serious injuries in the horse. Diagnosis is usually straightforward and a combination of radiography (including positive contrast studies) and synoviocentesis usually is necessary to determine which structures within the foot are involved. Superficial punctures usually carry a good prognosis but involvement of deep structures such as the distal phalanx or deep digital flexor tendon and navicular bursa adversely influence this.

Objective—To determine history; clinical, radiographic, ultrasonographic, and scintigraphic features; management; and outcome associated with third trochanter fractures in horses. Design—Retrospective case series. Animals—8 horses. Procedures—Records from 2000 to 2012 were reviewed, and signalment, case history, severity and duration of lameness, results of physical and lameness examinations, imaging findings, management, and outcome were evaluated. Results—All horses had a history of acute onset of severe lameness.

The aim of this study was to identify exercise-related risk factors for carpal and metacarpo- and metatarso-phalangeal (MCP/MTP) joint injury occurrence in young Thoroughbreds in flat race training. In a 2-year prospective cohort study, daily exercise and joint injury data were collected from horses in 13 training yards in England.

Summary

Reasons for performing study:

Identification of exercise history patterns that are related to catastrophic scapular fracture will facilitate prevention of racehorse fatalities.

Objectives:

To determine if exercise patterns are associated with scapular fracture in Thoroughbred (TB) and Quarter Horse (QH) racehorses.

Objective—To identify the prevalence of fragmentation of the proximal tubercle of the talus (FPTT) in a hospital population of horses, characterize the anatomic features of the affected area and fragments, and describe clinical findings, diagnosis, treatment, and outcome for horses with FPTT.

Design—Retrospective case series.

Animals—9 horses with FPTT.

A 20-year-old Argentinian gelding was evaluated for sudden weakness, muscular tremors, tachypnea, and reluctance to move. On admission, a mild bilateral hyperextension of the carpi was noticed. On the basis of the clinical, laboratory, and ultrasonographic findings, a diagnosis of diaphragmatic hernia was made. During confinement, the hyperextension of the carpi worsened. Because radiographic examination of both carpi revealed palmar-lateral diastasis of the accessory carpal bone, bilateral rupture of the palmar carpal ligament (PCL) was suspected.

Summary

Reasons for performing study: There are no detailed studies describing the resistance of equine tibiae and radii to side impact loads, such as a horse kick and a better understanding of the general long bone impact behavioural model is required.

Objectives: To quantify the typical impact energy required to fracture or fissure an equine long bone, as well as to determine the range and time course of the impact force under conditions similar to that of a horse kick.

Summary

Reasons for performing study: Although fractures of the metacarpal and metatarsal condyles are the most common long-bone fractures of Thoroughbred horses in training, limited data on variations in morphology and incidence have been published. Additionally, grouped analyses of previous studies from the UK and USA would permit comparison between study groups and the creation of a substantial pool of international data.

Summary

Reasons for performing the study: Lateral condylar (LC) fractures of the third metacarpus (McIII) are a common reason for euthanasia in racehorses, and may be the result of repetitive overloading or cumulative pathological change. Magnetic resonance imaging (MRI) allows monitoring of bone and cartilage to detect pathological and adaptive changes that may be precursors of fracture.

Objectives: To describe bone and cartilage MRI features in the distal condyles of McIII of Thoroughbred racehorses, with and without condylar fracture.
