Ultrasonographic morphology of the bicipital tendon and bursa in clinically normal quarter horses.

The research article is about a study where the bicipital tendons and bursae of 25 healthy Quarter Horses were examined using ultrasonography. The images obtained provided key anatomical data and demonstrated that ultrasonography is a useful tool in evaluating the tendon, bursa, and humerus in horses.

Ultrasonographic Examination

• The researchers carried out an ultrasonographic examination on 25 healthy adult Quarter Horses. This method was chosen as ultrasound provides real-time cross-sectional images of the underlying tissues and structures which cannot be inspected visually or palpated.
• Transversal images of both the right and the left bicipital tendons of the horses were collected with the help of a 7.5-MHz transducer, which was held in the frontal plane at the shoulder point.

Observations and Measurements

• The researchers observed that in the images, the bicipital tendon at the shoulder point appeared as a bilobate or two-lobed structure overlying the echo-producing surface of the humerus (the long bone in the upper arm or forelimb).
• Using the ultrasonographic images, they measured the distances from the skin surface to the tendon in different sagittal planes and the widths of different parts of the tendon. They also measured the width of the bicipital bursa, a small fluid-filled sac that provides a cushion between bones and tendons.
• All the measurements were recorded as median values and ranges to provide a comprehensive understanding of anatomy and possible variations.

Conclusion

• The study concluded that ultrasonographic imaging was an easy and effective method for evaluating the bicipital tendon, bursa, and the surface of the humerus in Quarter Horses.
• The results of this study could provide baseline reference data for veterinary medical practitioners when diagnosing tendon or bursa disorders in horses.
