Scalp injuries are all caused by direct external force, and the type of injury is related to the causative object. Blunt instruments can lead to scalp contusions, irregular lacerations, or scalp hematomas, while sharp objects produce clean-cut wounds. Hair being caught in machinery may cause scalp avulsion injuries. Observing scalp injuries is helpful in the diagnosis and treatment of craniocerebral injuries because:
- The characteristics of scalp injuries can indicate the nature and magnitude of the external force. The site of scalp injury often corresponds to the point of impact, and determining this point aids in inferring the location of brain injury;
- The scalp has rich blood supply, and post-traumatic bleeding can easily lead to hemorrhagic shock, especially in children;
- Although the scalp has strong resistance to infection and healing capacity, once infected, it may cause skull osteomyelitis or intracranial infections.
