Radiographic measurement from the lateromedial projection of the equine foot with navicular disease.
Radiographic measurements from the lateromedial projection of the equine foot were compared in three groups of horses. Group 1 consisted of 143 normal horses, group 2 were 60 horses with clinical navicular disease and group 3 were 161 horses with clinical and radiographic navicular disease. Several measurements tended to be larger in group 3 than group 1. An enlargement of the navicular bone was observed in proximodistal and dorsopalmar directions. Partial enlargement of the pedal bone was observed in groups 2 and 3. Few differences were observed between age classes. All horses aged four years and over had an increased length of the hoof in the dorosopalmar direction and a decrease of the cranial angle of the hoof. Enlargement of the navicular bone fits well into the concept of osteoarthrosis. The pedal bone was partly engaged. These findings may be an expression of a regional acceleratory phenomenon.
