Ultrasonographic observations of the flexor tendons and ligaments of the metacarpal region of horses

Observations were made in dorsal and sagittal planes of the ultrasonographic mean gray scale of the flexor tendons and ligaments of the metacarpal regions of 5 Thoroughbred geldings, during weight bearing and nonweight bearing. In images made when the horses were nonweight bearing, the mean gray scale of the superficial and deep digital flexor tendons and accessory ligament was significantly reduced, but that of the interosseous medius muscle (suspensory ligament) was not. When relaxed, collagen fiber bundles in the tendons and ligaments acted as diffuse, rather than specular, reflectors of ultrasonic waves leading to localized regions of hypoechogenicity and a consequent reduction in mean gray scale. The suspensory ligament, however, remained under tension during nonweight bearing and so mean gray scale was not reduced. Analyses of the ultrasonographic mean gray scale have the potential to provide quantitative data relating to the changes in echogenicity that develop in injured equine tendons and ligaments.
