When an open head injury occurs, pieces of bone or cerebrospinal fluid may enter the substance of the brain and significantly damage the tissue. The chances of infection are also high. Fortunately, open head injuries are typically diagnosed and treated immediately.
Considerable local damage can occur in the area of the brain immediately below the impact area, as well as more widespread damage.
An open head injury is more likely to receive immediate treatment, but also poses a high risk of infection through the wound.
Primary versus Secondary Effects
The direct application of physical forces damaging nerve fibres, blood vessels and other brain tissue are commonly referred to as the “primary” mechanisms of traumatic brain injury. Further complications are often called “secondary” mechanisms of brain injury.
A large number of secondary complications may occur including: haemorrhage (bleeding), haematoma or blood clot, raised intracranial pressure, hypoxia (loss of oxygen), brain swelling and post-traumatic epilepsy. Such complications require close monitoring and medical management.

In a closed head injury which may only appear to be a case of mild concussion, secondary effects such as a build up of pressure inside the skull are often the biggest causes for concern.
