They are chiefly due to local distortion of skull and sudden rotation of the head resulting from blow, which cause shear strain due to the pulling apart of the constituent particles of brain.These type of injuries are caused when the moving head is suddenly de-celerated by hitting a firm surface eg stinking of head on the ground during a fall. Subdural and subarachnoid hemorrage can occur due to these type of injury.A line drawn between the centres of coup and contrecoup indicates the direction of impact relative to head.They are not seen if the head is well fixed and cannot be rotated.
