**3. Biomechanics of injury (Hunting bow concept)**

The Mandible resembles a Hunting bow which is weak at the ends and strong in the midline and the condyles are enclosed by the glenoid fossa. So any blow to the midline of the mandible can cause bilateral condylar fracture and any blow to the parasymphysis may cause a contralateral fracture. This is based on the impact of the force (**Figure 3**) [5].

The fracture of condyle following trauma to the chin is an example of contrecoup injury. This is commonly found in soldiers who remain standing for a long time and hence referred to as Parade ground/Guardsman fracture**.**
