Assessment of ultrasonographic morphometric measurements of digital flexor tendons and ligaments of the palmar metacarpal region in Icelandic Horses.

The research paper provides an evaluation of ultrasonographic measurement of specific tendons and ligaments in the foot of Icelandic Horses. No significant differences were found due to age, sex, height, or body mass index, and the measurements were consistent with previous findings in other horse breeds.

Methodology

• The study involved 50 Icelandic horses in training, including two stallions, 30 geldings, and 18 mares. These horses varied in age from 4 to 20 years, and had a body mass index ranging between 149.1 to 250.11 kg/m2.
• Ultrasonographic images were captured using an 8 to 10 MHz linear transducer and a standoff pad. Images were taken in both forelimbs.
• Four specific measurements were made: cross-sectional area, circumference, dorsopalmar width, and lateromedial width. Each of these measurements was performed three times at five different regions of interest (ROIs).

Findings

• The results displayed a coefficient of variation for all measurements of each ROI less than 5%, indicating high precision in the measurements taken.
• There were no significant differences found in the measurements among horses of different ages, sexes, heights at the withers, or body mass indexes.
• A specific skin condition was noted that interfered with the ultrasonographic examination, but it did not drastically impact the overall results.

Conclusions

• The and consistency of measurements among the different horse attributes indicates a high degree of homogeneity in the structures of the horses’ flexor tendons and ligaments.
• The findings from this study align with the morphometric values obtained from similar studies in other breeds of horses. However, there were some differences noted, suggesting that measurements might slightly vary between breeds.
