Age-Related Changes of Elastic Fibers in Shoulder Capsule of Patients with Glenohumeral Instability: A Pilot Study

Figure 5

Shoulder articular capsule from a subject 40 years old of control group. Very few elastic fibers are detectable; their number is dramatically reduced in comparison with the patients of the other groups (Verhoeff’s iron hematoxylin staining, original magnification x 400; elastic fibers are stained in violet or purple, whereas collagen is in red).
