Ultrasonographic diagnosis of closed pedal bone fractures in bovine claws: An ex-vivo study in slaughterhouse specimens.

摘要: Abstract Pedal bone fractures are one of the most common fracture locations in adult cattle and can be diagnosed by radiographs two planes. Most bovine practitioners do not have access to such X-ray machines, but many use ultrasound units on a daily basis, primarily for reproductive medicine. For this reason, double-masked, randomized controlled study, we aimed investigate suitability ultrasonographic examination using 5 MHz linear transducer diagnosing closed pedal cattle. A total 54 hindlimb claws from slaughtered were prepared approximately 50% artificially fractured. All ultrasonographically examined twice examiners determine presence or absence their locations. Ultrasound results confirmed as reference standard method. determined ultrasonography situated within ±2 mm radiographically-determined zone. yielded calculated sensitivity 93%, specificity 91% an inter-rater reliability 0.77. The intra-rater 0.96 0.88. Examiner experience with images diagnosis could influenced diagnostic accuracy. We conclude that artificially-created ex-vivo ultrasonography; similar expected live animals. These should encourage veterinarians
