Figure 10. a) In the standard 55° navicular skyline image, sclerosis of the spongiosa is identified. The flexor cortex has decreased bone density, but a distinct defect is not visible. b) In a shallow angle (approximately 40°) navicular skyline image of the same horse, a focal irregular lucent defect is highlighted in the flexor cortex (white arrow). c) A mildly oblique upright lateromedial image catches the focal flexor cortex erosion in the distal aspect of the flexor cortex (white arrow).

A review of radiographic interpretation of the navicular bone

The navicular bone, or distal sesamoid bone, is located on the palmar aspect of the distal interphalangeal joint suspended by the collateral sesamoidean ligament, which attaches to the distal abaxial...

Figure 1. a. Lateromedial, (b) upright pedal and (c) navicular skyline radiographs of a 14-year-old Quarter Horse gelding with a normal navicular bone. Note the artifactual two linear lucent lines superimposed with proximal P2 as a result of the central sulcus of the frog in b.
