The tumour originated from the navicular bone.
However, evidence of navicular degeneration has been established in the fossil record of early horses.
Cartilage degeneration is common in navicular horses, usually along the flexor surface.
Each hind limb of the horse runs from the pelvis to the navicular bone.
The navicular bone in the horse is supported by the distal sesamoidean impar ligament and two collateral sesamoidean ligaments.
Excess tension can also cause exostoses where the ligaments attach to the navicular bone, giving the bone a canoe shape.
Tension placed on the ligaments that support the navicular bone.
The "head of talus" looks forward and medialward; its anterior articular or navicular surface is large, oval, and convex.
Strictly these should be termed the proximal sesamoid bones whereas the navicular bone should be referred to as the distal sesamoid bone.
