| Research Abstract |
In this study, we clarified the distribution of elastic and oxytalan fibers in a human sternoclavicular joint [SCJ] using a color image system and in extracellular matrices using immunoperoxidase staining. Fine elastic fibers [EFs] were scattered in the fibrous layr of the sternoclavicular disk. This articular disk was composed of a collagenous bundle on the sternum side of the articular disk in the SCJ and cellular components including connective tissue on the clavicular side of the articular disk. The thickness of the disk gradually increased from the inferior to superior portion. Collagen fibers type I,III and V and other extracellular matrices [ECMs] were detected in the hypertrophic zone in the clavicular and sternum side of the SCJ and in the connective tissue of the articulatio condylar. On the cervical surface of the articular disk, cellular activity was higher than on the sternum surface.
