Abstract:
Fractures of the capitellum account for less than 1% of all elbow fractures. Because they may be difficult to visualize on plain radiographs, the clinician must have a high index of suspicion for their diagnosis. Anatomic alignment of these fractures is imperative; slight residual displacement may result in significant loss of elbow motion. Surgical management is described with open reduction internal fixation using variable pitch headless screws, precontoured plates, or bioabsorbable pins. The optimal method of fixation depends on the fracture pattern and degree of comminution. If the fracture fragments are too small for stable fixation, excision of the fragments is recommended. Osteonecrosis, as well as, end-stage arthrosis requiring total elbow arthroplasty, has been reported as a rare, but potential, complication.

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,...
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 procedure...

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...
