Fracture of Navicular Bone

Summary

While degenerative disease of the navicular bone is common, actual fracture of the navicular bone is rare. Fracture usually results from direct and severe trauma. Exercise at speed over rocky ground can result in this fracture.

This fracture usually results in a very severe lameness with very slow improvement over time but poor likelihood of return to athletic performance.

DIAGNOSIS is most commonly radiographic. Radiographs must be interpreted carefully due to packing defects and cracks in the frog that can look like fractures.

TREATMENT is generally time, rest and pain management during the acute phase after injury.
