A Case of Depressed Skull Fracture of the Inner Table Alone
1Department of Neurosurgery, Wonkwnag University Hospital, Institute of Wonkwang Medical Science, Wonkwang University School of Medicine, Iksan, Korea.
Abstract:
A depressed skull fracture (DSF) is comminuted fractures in which the broken bones displace inward due to a blunt head trauma, such as when the broken outer table is located below the normal anatomical position of the inner table. The author presents an extremely rare case of a 38-year-old man with a DSF that affected only the inner table. In the literature, only 2 cases of DSF involving only the inner table have been reported, and the underlying mechanism remains unclear. The author believes that this phenomenon was not enough for the impact force to depress the outer table, but the tensile stress was sufficient to depress the relatively thin and weak inner table.

01:14Cranial 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,...

The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:22Sutures 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...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
