Objective:
We report the morbidity and mortality associated with fractures of the clivus and discuss management approaches specific to this unique diagnostic entity.
Methods:
We performed a boolean search of our electronic medical record database to identify patients with fractures of the clivus that were diagnosed using computed tomography of the head. A retrospective imaging and chart analysis was completed to further characterize the fractures and to analyze outcomes.
Results:
Between January 1999 and December 2007, 41 patients were identified with fractures of the clivus. We found a 0.21% overall incidence among all head-injured patients presenting to our institution and a 2.3% incidence among those patients with a cranial fracture. Ten of 41 patients (24.4%) died, and neurological and vascular complications associated with central cranial base fractures were observed in 19 of 41 patients (46%). Furthermore, associated cranial fractures remote from the central cranial base and associated intracranial hemorrhages were observed in 40 of 41 (97.6%) and 33 of 41 (80.5%) patients, respectively. In terms of outcomes, 26 of 41 patients (63.5%) had a Glasgow Coma Scale score of 12 or greater at the time of discharge from the hospital.
Conclusion:
We demonstrate a lower than previously reported mortality rate in patients with clival fractures. Nevertheless, as a result of location, fractures of the clivus were frequently associated with a high rate of complications and neurological sequelae.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
