Skull fractures have plagued humankind throughout history [1]. They occur when forces striking the head exceed the mechanical integrity of the calvarium. Significant skull fractures are often accompanied by moderate or severe intracranial injury and extracranial injuries associated with high-energy trauma, such as cervical and other spine fractures and thoracoabdominal injuries [2-9].

The epidemiology, mechanisms, clinical presentation, associated complications, and initial management of skull fractures in adults are reviewed here. Skull fractures in children and intracranial injuries are discussed separately. (See "Skull fractures in children" and "Intracranial epidural hematoma in adults" and "Subdural hematoma in adults: Etiology, clinical features, and diagnosis" and "Nonaneurysmal subarachnoid hemorrhage" and "Concussion and mild traumatic brain injury".)


The incidence of skull fractures among head injured adults who present to emergency departments (ED) is unknown. The parietal bone is most frequently fractured, followed by the temporal, occipital, and frontal bones [10]. Linear fractures are the most common, followed by depressed and basilar skull fractures. (See 'Definition and presentation of skull fracture types' below.)

Much of the data on skull fractures in adults come from studies of traumatic brain injury (TBI). Each year, approximately 1.7 million people sustain head injuries in the United States alone, with 1.3 million undergoing emergency evaluation [11].

According to one retrospective study of 207 head-injured patients, 37 percent of those with associated intracranial pathology sustained a linear skull fracture [12]. According to another retrospective study of 2254 cases of head trauma from assault, approximately one-third sustained a skull fracture [13].
