Ultrasonographic assessment of the equine palmar tendons

Abstract

Aim:The present study was conducted to evaluate the equine palmar tendon by ultrasonography (USG) in standing the position.Materials and Methods:USG of palmar tendons was performed in 40 adult horses using linear transducer having frequency of 10-18 MHz (e-soate, My Lab FIVE) and L52 linear array transducer (Titan, SonoSite) with frequencies ranging from 8 to 10 MHz. Palmar tendon was divided into 7 levels from distal to accessory carpal bone up to ergot in transverse scanning and 3 levels in longitudinal scanning.Results:The USG evaluation was very useful for diagnosis of affections of the conditions such as chronic bowed tendon, suspensory ligament desmitis, carpal sheath tenosynovitis and digital sheath effusions. The mean cross-sectional area (cm2) of affected tendons was significantly increased in affected than normal tendons. The echogenicity was also found reduced in affected tendons and ligaments along with disorganization of fiber alignment depending on the severity of lesion and injury.Conclusion:USG proved ideal diagnostic tool for diagnosis and post-treatment healing assessment of tendon injuries in horses.

Ultrasonographic‐based predictive factors influencing successful return to racing after superficial digital flexor tendon injuries in flat racehorses: A retrospective cohort study in 469 Thoroughbred racehorses in Hong Kong

“…Digitised ultrasonographic records of 1161 horses with a forelimb SDFT injury sustained while training or racing at the HKJC between 2003 and 2014 were reviewed retrospectively. Inclusion criteria for the study were: horses with images of a complete ultrasonographic examination at the primary assessment (defined as a minimum of 10 images, including transverse views at seven specific levels and three longitudinal views at three levels through the metacarpus ) and a full set of clinical data (including signalment, treatments, retirement date, and number of races before and after injury). Images were retrieved from a digital archive using an AGFA PACS system a.…”

Precision and accuracy of repeat ultrasound image acquisition and analysis of the cross-sectional areas of the equine flexor tendons of the forelimbs for follow-up assessments

“…Therefore, certain standards have been developed to increase the validity and accuracy of ultrasound imaging with regard to the examination of the equine digital flexor tendons (Denoix 1994, Miles et al 1996, van Schie et al 1998, Padaliya et al 2015. Studies have been carried out to determine quan-titative methods of evaluation such as grey scale analysis, including mean grey scale level or mean echogenicity (van .…”

Immediate effects of an artificial change in hoof angulation on the dorsal metacarpophalangeal joint angle and cross‐sectional areas of both flexor tendons

“…The probe was placed perpendicular to the most palmar surface of the metacarpal region. With this set‐up, transverse images of the SDFT and the DDFT were assessed 8 cm (zone 1B), 12 cm (zone 2A) and 16 cm (zone 2B) distal of the accessory carpal bone to obtain a good overview of the DDFT and SDFT 20 (Fig 1c). The probe was manipulated in all planes to obtain an optimal image showing the widest CSA possible of each tendon at the specific level.…”
