[Ultrasonographic study of pelvic bones structures in horse]

ABSTRACT

Pelvic bones injuries may cause lameness in horses. Radiography of pelvic region in horse is usually unsatisfactory due to difficulties and dangers. Meanwhile, advanced radiographic machines are not easily available which result in delay in diagnosis and treatment. In the current study, ultrasonography of the pelvic bones in 5 healthy horses, the approaches, and normal views were evaluated using A 2-5 MHZ convex probe for transcutaneous and 5-10 MHZ rectal probe for transrectal techniques. Ultrasonographic approaches for evaluating different parts of the pelvic region were defined and the bony structures were nominated. Pelvic sonography was indicative by the smooth and strong echo of the bone surface in most parts. Iliac body showed rough surface, Ischial tuber and arch just beneath the tail. The most difficult region for evaluation was coxofemoral joint. The dorsal surface of the joint was assessed by transcutaneous approach. Our findings showed that sonography can provide useful information about possible injuries of the pelvic region. This technique can be recommended for horse pelvic evaluation either before pelvic radiography or in the absence of advanced radiographic equipments
