Open Head Injury When the meninges and/or skull are broken and the brain penetrates one or both, that is called an open head injury. This is especially dangerous because a bone fragment or An open head injury occurs when the skull and membrane lining of the brain have been fractured, cracked or broken so that the brain is exposed or penetrated. 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. 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. © 2008 BIC |
