ABSTRACT

 

Vali R, Miri A Reference radiographic measurements for navicular bone of Dareh-shori horses, Onl J Vet Res., 21(7):428-432, 2017. Navicular abnormalities have long been considered a common cause of forelimb lameness on horses. Hooves of 10 normal Dareh-shiri horses were marked by contrast and radiographed with a portable X- ray unit using 5MAS and 80 kVP exposure with limb in vertical position. Dorsopalmar and lateromedial radiographs were fixed onto a horizontal viewing box and lines were drawn with a fine tipped pen.  Measurements were made from each radiograph  of the proximal-distal borders of the navicular bone in lateral projection, lateral-medial and proximal-distal in dorso-palmar projection after correcting for magnification The proximal-distal borders of the navicular bone measured 14.75 ± 1.4mm, lateral-medial 44.85 ± 3.64mm and proximal-distal 24.6 ± 3.34mm. Measurements differed from those reported in other horses breeds. The values could be used as reference for diagnosis of navicular abnormalities of front feet of Dareh-shori horses.

 

KEY-WORDS: Radiographic measurements, Front feet, Dareh-shori horses, Navicular bone.
