Which joint is part of the navicular region involved in navicular disease?

Navicular disease centers on the structures around the navicular bone in the hoof, including the coffin joint. The coffin joint, or distal interphalangeal joint, is where the second and third bones of the lower limb meet (the short pastern bone and the coffin bone). This area is intimately connected with the navicular apparatus—the navicular bone itself, the navicular bursa, and the deep digital flexor tendon—so problems in navicular disease often involve changes in this joint as well. The other joints listed—stifle, elbow, and fetlock—are located higher up the leg and are not part of the navicular region, so they aren’t the joints typically involved in navicular disease.
