Scalp laceration

Introduction A scalp laceration is a type of scalp injury. Most of the violent effects in the oblique or tangential direction are caused by the scalp. The torn scalp is often tongue-like or lobed, often with a pedicle attached to the head.

Cause

Cause: The scalp is torn due to a violation of the operating procedures, the scalp is torn into the rail wheel or belt, or the head scalp is torn due to a car accident.

Diagnosis: Most of the violent effects in the oblique or tangential direction are caused by the scalp. The torn scalp is often tongue-like or lobed, often with a pedicle attached to the head. Scalp laceration is generally not associated with skull and brain damage, but not always, occasionally there are skull fractures or intracranial hemorrhage. These patients have more blood loss, but less to the extent of shock.

Differential diagnosis

Differential diagnosis:

(1) scalp simple laceration: often due to sharp stab wound or cut injury, the crack is relatively straight, the wound edge is neat and no defect, the depth of the wound varies with the injury factor, except for a few sharp instruments directly penetrating or licking Outside the cranial incision, causing open head injury, most of the simple laceration is limited to the scalp, sometimes deep into the periosteum, but the skull is often intact and not accompanied by brain damage.

(2) complicated schizophrenia: often caused by blunt injury or head collision on foreign objects, the crack is irregular, the wound edge has contusion marks, and there is still fiber connection between the internal cracks, which is not completely broken off. There is no "organizational frustration" phenomenon. In forensic identification, if there is "tissue collapse" in the scalp contusion and laceration wound, it is often suggested that it is caused by metal or angular weapons. The shape of the wound often reflects the size and shape of the wound. Such wounds are often accompanied by skull fractures or brain damage. In severe cases, comminuted sag fractures or hole fractures can be penetrated into the skull. Therefore, foreign bodies such as hair, cloth dust or sediment are often embedded, which may cause infection. When checking the wound, be careful not to remove the foreign matter embedded in the skull to avoid sudden bleeding.
