| Fracture of Navicular Bone |  |
|
|
This may occur as a result of trauma or concussion to the foot or as a sequela of navicular disease (
Navicular Disease). It is much less common than pedal bone fracture but may be seen in fore- or hindfeet. Although pain is variable, hoof testers usually indicate the general site. Lameness is persistent and can be eliminated by palmar digital nerve block. Radiography confirms the diagnosis; however, care should be taken with interpretation because congenital
bipartite navicular bones can be confused with fractures.

| Treatment is prolonged rest and corrective trimming to alleviate tendon adhesions, but a satisfactory bony union at the fracture site seldom occurs. Surgical repair by lag screw has been described. Prognosis is guarded to poor. Although this is the type of malunion fracture that might respond to low-intensity magnetic field therapy, supportive evidence is lacking. |
