Radiographic assessment of normal parameters of forelimb distal phalanx in Turkmen horses.

Abstract

The Turkmen horse is one of the oldest breeds in the world with unique characteristics in agility, endurance and jump, being publicly acclaimed. Laminitis affects the limbs and decreases athletic performance. Radiographic evaluation is essential to confirm the sinking diagnosis in every breed of a horse suffering from laminitis. Since no information about distal phalanx radiographic measurements in this breed has been reported, the current study was designed and conducted. In the present study, 24 clinically sound registered Turkmen horses of both sexes (15 mares and nine stallions) were selected. Lateromedial radiographic views of both front distal phalanges were taken, focusing on the distal phalanx. After magnification correction, images were used to measure founder distances (FD) and other distal phalanx radiographic measurements using an image processing program. There was no significant difference between radiographic measurements of the left and right front feet. The FD had a significant positive correlation with weight. The horses under 3 years of age had a significantly greater U angle than the horses over the age of three. Also, palmarocortical length (PCL) in the Turkmen stallions was significantly higher than mares. In this investigation, PCL in horses under the age of three was significantly lower than horses over 3 years of age. The values determined in this study can be used as baseline data of front feet in Turkmen horses.
