Scalp injury is the most common component of craniocerebral injury. It can provide information about the position of the head, the general direction and magnitude of the impact force and other intracranial lesions that may accompany it. There are two kinds: closed and open. The former includes all kinds of scalp hematomas, while the latter includes abrasions, lacerations (including stab wounds, lacerations, lacerations with different degrees of inactivation of surrounding tissues) and scalp avulsion injuries.
Scalp injury generally has a good prognosis. Scalp avulsion injury is prone to shock due to large wound surface and much bleeding, so don't take strenuous exercise for the time being and have a good rest.
