Abstract:
Previously, the shape of the inferior glenoid has been described as a circle with a bare spot being the center of that circle. This cadaveric study was done to test that statement. Forty cadaveric scapulae were used in this study. Two researchers used a digital image analysis program to assess the shape of the inferior glenoid and measured the distances from the bare spot to the anterior, inferior, and posterior cartilage and the bone rim. In 39 of 40 scapulae, the inferior glenoid had the shape of a true circle. Statistical analysis showed that the center of the bare spot is not the mathematical center of the inferior glenoid, but the differences in distances to the anterior, inferior, and posterior rims were very small (1.16-2.41 mm). Both observations can be used for further development of methods for measuring glenoid bone loss in patients with anterior glenohumeral instability.

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,...

Cranial 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...
