Name of the disease in English
Mandibular fracture
The disease in brief
A kick from a fellow animal (for example from a mother suckled by a "thief" calf) or a shock to the metal tubes of the feeding stalls are causes of fracture; the frontal fracture which divides the jaw into 2 halves deforms less than the other fractures.
Clinic & diagnosis
In a bovine that is drooling or has difficulty eating, inspection of the mouth shows traces of shock, which the edema, pain and subcutaneous crepitation opposite the bone fracture line suggest are due to a fracture of the mandible.

Confirm a suspicion?
When in doubt, radiography may be the method of choice used on calves which are frequent victims.
Prognosis and treatment
If the fracture is non-displaced in a calf, an attempt can be made to muzzle the fracture, and spontaneous healing may occur. Solutions based on external fixators have been shown to reduce and consolidate very disastrous fractures.
Prevention
No specific prevention.
