Radiographic signs of navicular disease are seen in which bone?

Navicular disease centers on the navicular apparatus, with the navicular (distal sesamoid) bone as the primary site of pathology. On radiographs, the signs of this disease appear in the navicular bone itself, reflecting changes in its structure and its articulation with the distal interphalangeal joint. Look for features like sclerosis, lucency, fragmentation, or irregular margins on the navicular bone, and possible related changes at the palmar/solar surface or joint interface. While other structures can be affected secondarily by altered biomechanics, the radiographic evidence that defines navicular disease is located in the navicular bone rather than the fetlock, pastern, or coffin bones.
