REASONS FOR PERFORMING STUDY: Ultrasound is widely used in horses with stifle lameness, yet limited information is available regarding the appearance of normal and injured lateral patellar ligaments (LPL).

OBJECTIVES: To map the normal ultrasonographic appearance of the LPL. To describe the clinical and ultrasonographic features of LPL injuries.

STUDY DESIGN: Descriptive study of healthy horses and retrospective case series.

To determine the association between ultrasonographic (US) and anatomopathologic findings, an US examination was performed postmortem on the fetlock and associated structures of 37 equine forelimb specimens. All these specimens exhibited images suggestive of lesions on the ultrasound examination. Subsequently, these limbs were dissected and underwent an anatomopathologic study.

Objective To describe an ultrasound assisted arthroscopic approach for removal of non-articular basilar sesamoid fragments in Thoroughbred yearlings. Animals Thoroughbred yearlings (n = 7). Methods Basilar sesamoid fragments identified during pre-sale radiographic examination were removed using a palmar/plantar arthroscopic approach to the fetlock joint and ultrasonographic guidance. Complete fragment removal was confirmed by ultrasonography and radiography.

Summary Reasons for performing study Accurate radiological and ultrasonographic descriptions of frontal plane fractures of the accessory carpal bone (ACB) are lacking, and implications of these fractures for the carpal sheath and its contents have not previously been reported.

Reasons for performing study

Lysis of the axial aspect of equine proximal sesamoid bones (PSBs) is a rare condition reported to have septic or traumatic origins. Limited information exists regarding imaging of nonseptic axial osteitis of a PSB.

Tendon and ligament injuries are common causes of impaired performance in equine athletes. Gray-scale ultrasonography is the current standard method for diagnosing and monitoring these injuries, however this modality only provides morphologic information. Elastography is an ultrasound technique that allows detection and measurement of tissue strain, and may provide valuable mechanical information about equine tendon and ligament injuries.

Objective—To ultrasonographically quantify experimentally induced effusion of the distal interphalangeal (DIP) joint of horses and compare results with those obtained with palpation.

Sample—8 forelimbs from equine cadavers and forelimbs of 5 mares.

Objective—To evaluate the usefulness of Doppler ultrasonography as a method to assess changes in digital vascular dynamics in horses with systemic inflammatory response syndrome (SIRS) or laminitis.

Design—Cross-sectional study.

Animals—42 adult Andalusian horses.

Previous studies have proposed that standard ultrasonography may not adequately represent the pertinent anatomic characteristics of the equine proximal suspensory ligament. The purpose of the study was to compare the use of standard ultrasonography, angle contrast ultrasonography, MRI, and histology for identification of the anatomic characteristics of the normal equine suspensory ligament in the forelimb. Horses free from forelimb lameness with no palpable abnormalities in the region of the suspensory ligament were included in the study.
